   The Vascular Solutions Duett(TM) sealing device utilizes a dual approach.
The Duett balloon catheter provides a temporary seal on the inside of the
femoral artery, while the flowable, thrombin-based procoagulant is applied
directly to the outer surface of the artery to create a permanent seal.

                               PROSPECTUS SUMMARY

   This summary highlights information contained elsewhere in this prospectus.
Because this is only a summary, it does not contain all of the information that
may be important to you. You should read the entire prospectus carefully. You
should consider the information under "Risk Factors" and in our financial
statements and the notes relating to these financial statements, together with
the information included elsewhere in this prospectus, before deciding to
invest in our common stock.

                                  Our Business

   We manufacture, market and sell the Vascular Solutions Duett sealing device,
which enables cardiologists and radiologists to rapidly seal the puncture site
following catheterization procedures such as angiography, angioplasty and
stenting. Our product combines a simple balloon catheter delivery mechanism
with a powerful, proprietary procoagulant, or blood clotting mixture. We
believe our product offers advantages over both manual compression and the
three other FDA-approved devices used to seal the puncture site following the
catheterization procedure. We began selling our product in Europe in February
1998. On June 22, 2000, we received approval from the FDA of our premarket
approval application for the sale of the Duett sealing device in the United
States. As a result, we very recently commenced selling our Duett sealing
device in the United States. Over 15,000 deployments of our device have been
performed worldwide.

   We believe that we are well-positioned to capture a substantial share of the
vascular sealing device market as our Duett sealing device offers clinical,
patient comfort and economic benefits by:

  .  completely sealing the puncture site, even in patients receiving
     powerful anti-clotting medications;

  .  leaving nothing behind in the artery that could cause an infection or
     interfere with accessing the puncture site again, if that becomes
     necessary;

  .  enabling a rapid deployment with an easy-to-use, one-size-fits-all
     device; and

  .  providing improved patient comfort and increased provider efficiencies
     by minimizing the amount of manual compression and the period of
     immobile bed rest.

   The primary factors underlying the market opportunity for vascular sealing
devices are that (1) there are a significant and growing number of
catheterization procedures being performed, and (2) the substantial majority of
the resulting puncture sites are still being sealed using manual compression.
In 1999, over seven million catheterization procedures were performed. This
number is expected to grow by more than 5% each year for the next three years
principally due to the increasing incidence of cardiovascular disease. Vascular
sealing devices were introduced in the United States in late 1995 and have been
adopted by physicians, as evidenced by the $160 million of these devices that
were sold worldwide in 1999. Nonetheless, over 85% of the arterial punctures
created in 1999 still were sealed using manual compression.

   During 1999, we had net sales of $1,429,094 and a net loss of $7.9 million.
Because of our plans to invest heavily in sales and marketing, hire additional
employees and expand our commercialization, we expect to incur significant net
losses through at least December 31, 2000. Our success will depend on the
medical community's acceptance of our Duett sealing device.

                                  RISK FACTORS

   You should carefully consider the risks described below before deciding to
purchase our common stock. The risks and uncertainties described below are not
the only ones facing our company. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial may also impair our
business operations. If any of the following risks occur, our business,
financial condition or results of operations could be seriously harmed. In such
case, the trading price of our common stock could decline, and you could lose
all or part of your investment.

Because we only began product development in February 1997, we have a limited
operating history upon which to evaluate our potential for future success

   We began product development in February 1997 and began to generate
international sales in February 1998. Accordingly, we have only three years of
operating history upon which you can evaluate our business and prospects. You
must consider the risks and uncertainties frequently encountered by early
stage, single-product medical device companies like ours in a new and evolving
market, such as the vascular sealing device market. If we are unsuccessful in
addressing these risks and uncertainties, our business will be seriously
harmed.

We have been named as the defendant in two patent infringement lawsuits and may
face additional intellectual property infringement claims in the future which
could prevent us from manufacturing and selling our product or result in our
incurring substantial costs and liabilities

   An adverse determination in any intellectual property litigation or
interference proceedings could prohibit us from selling our product, subject us
to significant liabilities to third parties or require us to seek licenses from
third parties. The costs associated with these license arrangements may be
substantial and could include ongoing royalties. Furthermore, the necessary
licenses may not be available to us on satisfactory terms, if at all. Adverse
determinations in a judicial or administrative proceeding or failure to obtain
necessary licenses could prevent us from manufacturing and selling our product.

   On July 23, 1999, we were named as the defendant in a patent infringement
lawsuit brought by Datascope Corp. in the United States District Court for the
District of Minnesota. The complaint requested a judgment that our Duett
sealing device infringes and, following FDA approval, will infringe a United
States patent held by Datascope and asks for relief in the form of an
injunction that would prevent us from selling our product in the United States
as well as an award of attorneys' fees, costs and disbursements. On March 15,
2000, the court granted summary judgment dismissing all of Datascope's claims,
subject to the right of Datascope to recommence the litigation after our
receipt of FDA approval of our Duett sealing device. On July 12, 2000, after
our receipt of FDA approval, Datascope recommenced this litigation, alleging
that the Duett sealing device infringes a United States patent held by
Datascope and requesting relief in the form of an injunction that would prevent
us from selling our product in the United States, damages caused by our alleged
infringement, and other costs, disbursements and attorneys' fees. It is not
possible to predict the timing or outcome of this lawsuit, including whether we
will be prohibited from selling our Duett sealing device in the United States
or internationally, or to estimate the amount or range of potential loss, if
any.

   On September 22, 1999, we received a letter from the Daig division of St.
Jude Medical, Inc. claiming that the manufacture, use, marketing and sale of
our Duett sealing device infringes upon certain United States patents licensed
by Daig. The letter referenced a prior letter dated August 18, 1998 from us to
the prior licensee of those patents in which we made a proposal intended to
avoid

                                       5
<PAGE>

the anticipated litigation over those patents. The proposed license was
rejected. On July 3, 2000, we were named as the defendant in a patent
infringement lawsuit brought by St. Jude Medical and Daig Corporation in the
United States District Court for the District of Minnesota. The complaint
requests a judgment that our Duett sealing device infringes a series of four
patents held by St. Jude Medical and asks for relief in the form of an
injunction that would prevent us from selling our product in the United States,
damages caused by the manufacture and sale of our product, and other costs,
disbursements and attorneys' fees. It is not possible to predict the timing or
outcome of this lawsuit, including whether we will be prohibited from selling
our Duett sealing device in the United States or internationally, or to
estimate the amount or range of potential loss, if any.

   The interventional cardiology industry is characterized by numerous patent
filings and frequent and substantial intellectual property litigation.
Companies in the interventional cardiology industry in general, and in vascular
sealing in particular, have employed intellectual property litigation in an
attempt to gain a competitive advantage. We are aware of many United States
patents issued to other companies in the vascular sealing field which describe
vascular sealing devices. Each of the three vascular sealing products with
which our Duett sealing device competes has been subject to infringement
litigation. It is likely that we will become the subject of additional
intellectual property claims in the future related to our Duett sealing device.
Intellectual property litigation in recent years has proven to be very complex,
and the outcome of such litigation is difficult to predict.

   Our defense of the Datascope claim, the St. Jude Medical claim and any other
intellectual property claims filed in the future, regardless of the merits of
the complaint, could divert the attention of our technical and management
personnel away from the development and marketing of the Duett sealing device
for significant periods of time. The costs incurred to defend the Datascope
claim, the St. Jude Medical claim and other future claims could be substantial
and seriously harm us, even if our defense is ultimately successful.

We will not be successful if the vascular sealing device market does not adopt
our new sealing methodology

   We have sold only a limited number of our Duett sealing devices to date and
have only very recently commenced sales of our product in the United States,
which we believe represents the largest market for vascular sealing devices.
Our success will depend on the medical community's acceptance of our Duett
sealing device. We cannot predict how quickly, if at all, the medical community
will accept our Duett sealing device, or, if accepted, the extent of its use.
Our potential customers must:

  .  believe that our device offers benefits compared to the methodologies
     and/or devices that they are currently using to seal vascular punctures;

  .  believe that our device is worth the price that they will be asked to
     pay; and

  .  be willing to commit the time and resources required to change their
     current methodology.

   If we encounter difficulties introducing our Duett sealing device into the
United States market or expanding our presence in markets outside the United
States, our business will be seriously harmed.

We currently rely on the Duett sealing device as our sole source of revenue

   We have developed only one product which is being sold in a limited number
of international markets and have only very recently received FDA approval for
sale in the United States. Even if we were to develop additional products, FDA
approval would be required in order to sell them in the United States.
Preparation of the requisite materials to seek FDA approval and the approval
process itself require a substantial amount of time and money. Therefore, we do
not expect to be in a position

                                       6
<PAGE>

to sell additional products in the foreseeable future. As a result, our success
is solely dependent on the success of our Duett sealing device. If our Duett
sealing device is not successful, our business will be seriously harmed.

We have incurred losses and we may not be profitable in the future

   Since we commenced operations in February 1997, we have incurred net losses
from costs relating to the development and commercialization of our Duett
sealing device. At March 31, 2000, we had an accumulated deficit of $16.6
million. We expect to continue to significantly increase our sales and
marketing, research and development and general and administrative expenses. In
particular, we are in the process of hiring, training and deploying a direct
sales force to sell our Duett sealing device in the United States. Because of
our plans to invest heavily in sales and marketing, hire additional employees
and expand our commercialization, we expect to incur significant net losses
through at least December 31, 2000. Our business strategies may not be
successful and we may not be profitable in any future period. If we do become
profitable, we cannot be certain that we can sustain or increase profitability
on a quarterly or annual basis.

Our future operating results are difficult to predict and may vary
significantly from quarter to quarter, which may adversely affect the price of
our common stock

   The very recent FDA approval of our Duett sealing device and history of
losses make prediction of future operating results difficult. You should not
rely on our past revenue growth as any indication of future growth rates or
operating results. The price of our common stock will likely fall in the event
that our operating results do not meet the expectations of analysts and
investors. Comparisons of our quarterly operating results are an unreliable
indication of our future performance because they are likely to vary
significantly based on many factors, including:

  .  the results of the introduction of our Duett sealing device into the
     United States market;

  .  the effect of intellectual property disputes;

  .  the demand for and acceptance of our Duett sealing device;

  .  the success of our competition and the introduction of alternative means
     for vascular sealing;

  .  our ability to command favorable pricing for our Duett sealing device;

  .  the growth of the market for vascular sealing devices;

  .  the expansion and rate of success of our direct sales force in the
     United States and our independent distributors internationally;

  .  actions relating to ongoing FDA compliance;

  .  the size and timing of orders from independent distributors or
     customers;

  .  the attraction and retention of key personnel, particularly in sales and
     marketing, regulatory, manufacturing and research and development;

  .  unanticipated delays or an inability to control costs with respect to
     our Duett sealing device;

  .  our ability to introduce new products and enhancements in a timely
     manner;

                                       7
<PAGE>

  .  general economic conditions as well as those specific to our customers
     and markets; and

  .  seasonal fluctuations in revenue due to the elective nature of some
     procedures.

Our direct sales efforts may not be successful because we have no operating
history with a direct sales force

   Because we have only very recently received regulatory approval to sell our
Duett sealing device in the United States, we have no operating history with a
direct sales force. We are in the process of hiring a direct sales force,
including clinical specialists to perform physician training, to commercialize
our Duett sealing device in the United States. We currently anticipate spending
approximately $18.5 million during the period from April 1, 2000 through
December 31, 2001 to hire, train and deploy our direct sales force. We believe
that our new salespeople and clinical specialists will require approximately
three months from their hiring date to become productive selling and training
physicians to use our Duett sealing device. Furthermore, we believe that there
is significant competition for direct sales personnel and clinical specialists
with the advanced sales skills and technical knowledge we require. We may not
be able to obtain, train and retain direct sales personnel and the future sales
efforts of our direct sales force may not be successful.

We may face product liability claims that could result in costly litigation and
significant liabilities

   The manufacture and sale of medical products entail significant risk of
product liability claims. The medical device industry in general has been
subject to significant medical malpractice litigation. Any product liability
claims, with or without merit, could result in costly litigation, reduced
sales, cause us to incur significant liabilities and divert our management's
time, attention and resources. Because of our limited operating history and
lack of experience with these claims, we cannot be sure that our product
liability insurance coverage is adequate or that it will continue to be
available to us on acceptable terms, if at all.

The market for vascular sealing devices is highly competitive and will likely
become more competitive, and our competitors may be able to respond more
quickly to new or emerging technologies and changes in customer requirements
that may render our Duett sealing device obsolete

   The existing market for vascular sealing devices is intensely competitive.
We expect competition to increase further as additional companies begin to
enter this market and/or modify their existing products to compete directly
with ours. Our primary competitors are Abbott Laboratories (through its
subsidiary Perclose, Inc.), Datascope Corp. and St. Jude Medical, Inc., which
sells a product developed by Kensey Nash Corporation. These companies have:

  .  better name recognition;

  .  broader product lines;

  .  greater sales, marketing and distribution capabilities;

  .  significantly greater financial resources;

  .  larger research and development staffs and facilities; and

  .  existing relationships with some of our potential customers.

                                       8
<PAGE>

   We may not be able to effectively compete with these companies. In addition,
broad product lines may allow our competitors to negotiate exclusive, long-term
supply contracts and offer comprehensive pricing for their products. Broader
product lines may also provide our competitors with a significant advantage in
marketing competing products to group purchasing organizations and other
managed care organizations that are increasingly seeking to reduce costs
through centralized purchasing. Greater financial resources and product
development capabilities may allow our competitors to respond more quickly to
new or emerging technologies and changes in customer requirements that may
render our Duett sealing device obsolete.

We currently depend on the international marketing and sales efforts of a
limited number of independent distributors

   Our Duett sealing device is sold internationally through independent
distributors in Germany, Norway, Italy, Austria, the United Kingdom, Denmark,
Switzerland, Finland, Sweden, Greece, Belgium, Spain, the Netherlands, Taiwan
and Hong Kong. Our international sales are largely dependent on the marketing
efforts of, and sales by, these distributors. Sales through distributors are
subject to several risks, including the risk of financial instability of
distributors and the risk that distributors will not effectively promote our
Duett sealing device. Loss or termination of these distribution relationships
could seriously harm our international sales efforts and could result in our
repurchasing unsold inventory from former distributors by virtue of local laws
applicable to distribution relationships, provisions of distribution agreements
or negotiated settlements entered into with our distributors. Sales to our
German, Norwegian and Italian distributors accounted for 29%, 20% and 12% of
net sales for the year ended December 31, 1999.

Our international sales are subject to a number of risks that could seriously
harm our ability to successfully commercialize our Duett sealing device in any
international market

   Substantially all of our sales to date have been outside the United States.
Our international sales are subject to several risks, including:

  .  the impact of recessions in economies outside the United States;

  .  greater difficulty in collecting accounts receivable and longer
     collection periods;

  .  unexpected changes in regulatory requirements, tariffs or other trade
     barriers;

  .  weaker intellectual property rights protection in some countries;

  .  potentially adverse tax consequences; and

  .  political and economic instability.

   The occurrence of any of these events could seriously harm our future
international sales and our ability to successfully commercialize our Duett
sealing device or any future product in any international market.

We have limited manufacturing experience and may encounter difficulties in
expanding our manufacturing operations which could seriously harm our business

   We have limited experience in manufacturing our Duett sealing device. Until
very recently, we have manufactured the Duett sealing device in limited
quantities for international sales and clinical studies in the United States.
We do not have experience in manufacturing our Duett sealing device in

                                       9
<PAGE>

substantial commercial quantities. We believe our current facilities are
adequate for our projected production of our Duett sealing device for the next
year, but future facility requirements will depend largely on future sales of
our product in the United States. We may encounter unforeseen difficulties in
expanding our production of our Duett sealing device and new products,
including problems involving production yields, quality control and assurance,
component supply and shortages of qualified personnel, compliance with FDA
regulations and requirements regarding good manufacturing practices, and the
need for further regulatory approval of new manufacturing processes.
Difficulties encountered by us in expanding our manufacturing capabilities
could seriously harm our business.

Our business and results of operations may be seriously harmed by changes in
third-party reimbursement policies

   We could be seriously harmed by changes in reimbursement policies of
governmental or private healthcare payors, particularly to the extent any
changes affect reimbursement for catheterization procedures in which our Duett
sealing device is used. Failure by physicians, hospitals and other users of our
Duett sealing device to obtain sufficient reimbursement from healthcare payors
for procedures in which our Duett sealing device is used or adverse changes in
governmental and private third-party payors' policies toward reimbursement for
such procedures would seriously harm our business.

   In the United States, healthcare providers, including hospitals and clinics
that purchase medical devices such as our Duett sealing device, generally rely
on third-party payors, principally federal Medicare, state Medicaid and private
health insurance plans, to reimburse all or part of the cost of catheterization
procedures. We believe that in a prospective payment system, such as the system
currently used by Medicare, and in many managed care systems used by private
healthcare payors, the cost of the Duett sealing device will be incorporated
into the overall cost of the procedure and that there will be no separate,
additional reimbursement for our product. The Health Care Financing
Administration is in the process of implementing a new Medicare prospective
payment system for hospital outpatient services, scheduled to be effective on
August 1, 2000. It is uncertain what impact this new system may have on sales
of our product.

   In international markets, acceptance of our Duett sealing device is
dependent in part upon the availability of reimbursement within prevailing
healthcare payment systems. However, we are unaware of any hospitals that
receive specific, cost-based, direct reimbursement for the use of our Duett
sealing device. Reimbursement and healthcare payment systems in international
markets vary significantly by country. Our failure to receive international
reimbursement approvals could have a negative impact on market acceptance of
our Duett sealing device in the markets in which these approvals are sought.

Our Duett sealing device and our manufacturing activities are subject to
extensive governmental regulation that could prevent us from selling our Duett
sealing device in the United States or introducing new and improved products

   Our Duett sealing device and our manufacturing activities are subject to
extensive regulation by a number of governmental agencies, including the FDA
and comparable international agencies. We are required to:

  .  obtain the approval of the FDA and international agencies before we can
     market and sell our products;

                                       10
<PAGE>

  .  satisfy these agencies' content requirements for all of our labeling,
     sales and promotional materials; and

  .  undergo rigorous inspections by these agencies.

   Compliance with the regulations of these agencies may delay or prevent us
from introducing any new model of our Duett sealing device or other products.
Furthermore, we may be subject to sanctions, including temporary or permanent
suspension of operations, product recalls and marketing restrictions if we fail
to comply with the laws and regulations pertaining to our business.

   We are also required to demonstrate compliance with the FDA's quality system
regulations. The FDA enforces its quality system regulations through pre-
approval and periodic post-approval inspections. These regulations relate to
product testing, vendor qualification, design control and quality assurance, as
well as the maintenance of records and documentation. If we are unable to
conform to these regulations, the FDA may take actions which could seriously
harm our business.

   We are currently conducting two post approval studies of our Duett sealing
device as required by the FDA. It is likely that we will conduct further
studies on the use of our Duett sealing device for the foreseeable future. The
FDA and international regulatory agencies may restrict or withdraw their
approval of our Duett sealing device if additional information becomes
available to support this action through these studies or otherwise.

The loss of, or interruption of supply from, key vendors, including single
source suppliers, could limit our ability to manufacture our Duett sealing
device

   We purchase components used in our Duett sealing device from various
suppliers and rely on single sources for the collagen and thrombin components
of our Duett sealing device procoagulant. There are currently no FDA-approved
alternative suppliers of thrombin and very few FDA-approved alternative
suppliers of collagen. Because it requires FDA approval, establishing
additional or replacement suppliers for thrombin would require a lead-time of
at least two years and would involve significant additional costs. Any supply
interruption from key vendors or failure by us to engage alternative vendors
may limit our ability to manufacture our Duett sealing device and could
therefore seriously harm our business.

Our failure to expand our management systems and controls to support
anticipated growth could seriously harm our business

   Our operations are growing rapidly and we expect this expansion to continue
as we execute our business strategy. Our total number of employees grew from 48
on April 1, 1999 to 86 on June 1, 2000. We anticipate further increases in the
number of our employees. Sustaining our growth has placed significant demands
on management and our administrative, operational, personnel and financial
resources. Accordingly, our future operating results will depend on the ability
of our officers and other key employees to continue to implement and improve
our operational, client support and financial control systems, and effectively
expand, train and manage our employee base. We may not be able to manage our
growth successfully and inability to sustain or manage our growth could
seriously harm our business.

                                       11
<PAGE>

We may be required to delay, reduce or eliminate some or all of our research
and development activities or sales and marketing efforts if we fail to obtain
additional funding that may be required to satisfy our future capital
expenditure needs

   We plan to continue to spend substantial funds to expand our sales and
marketing activities, our research and development activities and our inventory
requirements. Our future liquidity and capital requirements will depend upon
numerous factors, including actions relating to regulatory matters, the costs
and timing of expansion of sales and marketing, manufacturing and research and
development activities, the extent to which our Duett sealing device gains
market acceptance and competitive developments. Any additional required
financing may not be available on satisfactory terms, if at all. If we are
unable to obtain financing, we may be required to delay, reduce or eliminate
some or all of our research and development activities or sales and marketing
efforts.

Concentration of ownership of our company may give some shareholders
substantial influence and may prevent or delay a change in control of our
company

   We anticipate that our executive officers and directors, together with their
affiliates, will, in the aggregate, own approximately 5,774,114 shares, or
47.3%, of our outstanding common stock following the completion of this
offering. These shareholders may be able to exercise substantial influence over
all matters requiring shareholder approval, including the election of directors
and approval of significant corporate transactions. This concentration of
ownership may also have the effect of delaying or preventing a change in
control of our company.

Entities affiliated with Stephens Inc. may be able to control our management,
operations and affairs

   Entities affiliated with Stephens Inc. will own approximately 2,717,180
shares, or 22.5% of our outstanding common stock following the completion of
this offering. These entities have contributed their shares of our common stock
to a voting trust, which must vote the shares "for" or "against" proposals
submitted to our shareholders in the same proportion as votes cast "for" and
"against" those proposals by all other shareholders. As long as these shares
are held in the voting trust, these affiliates of Stephens Inc. cannot control
our business. However, if the voting trust were terminated, Stephens Inc.
might, depending on the number of shares voted on a particular matter,
effectively be able to exercise substantial influence over all matters
requiring shareholder approval, including the election of directors and
approval of significant corporate transactions. If the voting trust were
terminated, Stephens Inc. might also be prohibited from making a market in our
common stock.

Our articles of incorporation and Minnesota law may discourage an acquisition
of our company

   Provisions of our articles of incorporation and Minnesota law could make it
more difficult for a third party to acquire us, even if doing so would be
beneficial to our shareholders.

Management could spend or invest the proceeds of this offering in ways with
which the shareholders may not agree, including the possible pursuit of other
market opportunities

   Our management can spend or invest the proceeds from this offering in ways
with which the shareholders may not agree. The investment of these proceeds may
not yield a favorable return. Furthermore, because the market for vascular
sealing devices is new and emerging, we may in the

                                       12
<PAGE>

future discover new opportunities that are more attractive. As a result, we may
commit resources to these alternative market opportunities. This action may
require us to limit or abandon our current focus on developing, manufacturing
and marketing our Duett sealing device. If we change our product focus we may
face risks that may be different from the risks associated with the vascular
sealing device market.

The price of our common stock could be highly volatile due to a number of
factors

   An active trading market for our common stock may not develop or be
sustained after completion of this offering. The initial public offering price
of our common stock may not be indicative of the prices that will prevail in
the public market after the offering, and the market price of our common stock
could fall below the initial public offering price.

   The trading price of our common stock may fluctuate widely as a result of a
number of factors, including:

  .  performance of our Duett sealing device in the United States market;

  .  actions taken by the FDA concerning our products;

  .  market perception and customer acceptance of vascular sealing devices;

  .  increased competition;

  .  litigation concerning intellectual property rights;

  .  the loss of significant orders;

  .  general conditions in the medical device industry; and

  .  changes in earnings estimates by analysts.

   In addition, the stock market for medical device companies has experienced
extreme price and volume fluctuations, which have often been unrelated to the
operating performance of the companies experiencing these fluctuations.

Future sales of our common stock in the public market could cause our stock
price to fall

   If our shareholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could fall. Upon completion of the offering, we will have 12,055,168
outstanding shares of common stock, assuming no exercise of outstanding options
or warrants after June 1, 2000. Other than the shares sold in this offering
which will be freely tradeable, 302,250 shares will become freely tradeable as
of the date of this prospectus, an additional 87,800 shares will be freely
tradeable 90 days after the date of this prospectus and 8,665,118 shares will
become freely tradeable at varying dates beginning 180 days after the date of
this prospectus upon the expiration of lock-up agreements between our existing
shareholders and the underwriters.

If holders of our common stock that have registration rights require us to
register a large number of their shares for sale into the public market, the
market price of our common stock and our ability to raise needed capital could
be significantly harmed

   One hundred eighty days after the date of this prospectus, the holders of
3,777,777 shares of our common stock, which represent 31% of our outstanding
common stock after this offering, and the

                                       13
<PAGE>

holders of warrants to purchase 168,000 shares of our common stock will be
entitled to have the resale of their shares registered under the Securities Act
of 1933. If these holders cause a large number of shares to be registered and
sold in the public market, such sales could seriously harm the market price for
our common stock. In addition, if we include in a company-initiated
registration shares held by these holders pursuant to the exercise of their
registration rights, such sales may have a negative impact on our ability to
raise needed capital.

                                USE OF PROCEEDS

   We estimate the net proceeds to us from the sale of the 3,000,000 shares of
our common stock offered pursuant to this offering to be approximately $33.1
million, or approximately $38.2 million if the underwriters' over-allotment
option is exercised in full, based on an assumed initial public offering price
of $12.00 per share less the underwriting discount and estimated offering
expenses we expect to pay.

   We intend to use the net proceeds from this offering primarily for operating
expenses, including increased sales and marketing expenses associated with the
very recent commercial launch of our Duett sealing device in the United States.
We currently anticipate spending approximately $18.5 million during the period
from April 1, 2000 through December 31, 2001 to hire, train and deploy a direct
sales force in the United States. Any remaining proceeds will be used for
working capital and other general corporate purposes. The amounts that we
actually spend for each of these purposes will vary significantly depending on
a number of factors, including the amount of cash we generate from operations
and the progress of our regulatory and sales and marketing efforts. As a
result, we will retain broad discretion in the allocation of the net proceeds
from this offering.

   Pending these uses, we intend to invest the net proceeds from this offering
in short-term, investment-grade, interest-bearing securities.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our capital stock and
do not anticipate paying any cash dividends in the foreseeable future. We
currently intend to retain future earnings to fund the development and growth
of our business.

                                 CAPITALIZATION

   The following table describes our capitalization as of March 31, 2000:

  .  on a pro forma basis to give effect to the automatic conversion of all
     shares of preferred stock into an aggregate of 3,777,777 shares of
     common stock upon the closing of this offering; and

                                    DILUTION

   If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock after this offering. Net tangible book value dilution per
share represents the difference between the amount per share paid by purchasers
of shares of common stock in this offering and the pro forma, adjusted net
tangible book value per share of common stock immediately after completion of
this offering.

   Our pro forma, net tangible book value as of March 31, 2000, after giving
effect to the conversion of our outstanding preferred stock into common stock
in connection with this offering, was $9,281,589 or $1.03 per share of common
stock. Net tangible book value per share as of a specified date is equal to
total tangible assets less total liabilities, divided by the number of
outstanding shares of common stock at such date. After giving effect to our
sale of the 3,000,000 shares of common stock offered hereby at an assumed
initial public offering price of $12.00 per share and after deducting the
underwriting discount and estimated offering expenses we expect to pay, our pro
forma, adjusted net tangible book value as of March 31, 2000 would have been
$42,411,589 or $3.52 per share of common stock. This represents an immediate
increase in pro forma, adjusted net tangible book value to existing
shareholders of $2.49 per share and an immediate dilution to new investors of
$8.48 per share. The following table illustrates the per share dilution:

   The tables and calculations above assume no exercise of the underwriters'
over-allotment option to purchase up to an additional 450,000 shares of common
stock. This information also assumes no exercise of options outstanding under
our stock option plan or other outstanding options or warrants to purchase
shares of our common stock. On March 31, 2000, there were options outstanding
to purchase 943,551 shares of common stock under our stock option plan and
268,000 shares of common stock issuable upon exercise of outstanding stock
option and warrant agreements. To the extent that any of these options or
warrants are exercised, there will be further dilution to new investors.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   You should read the following discussion and analysis in conjunction with
"Selected Financial Data" and our financial statements and the related notes
included elsewhere in this prospectus. This discussion contains forward-looking
statements that involve risks and uncertainties. Our actual results may differ
significantly from those anticipated in these forward-looking statements as a
result of various factors, including, but not limited to, those described under
"Risk Factors" and elsewhere in this prospectus.

Overview

   Since we commenced operations in February 1997, we have been engaged in the
design, development, clinical testing and, more recently, the manufacture and
sale in international markets of the Vascular Solutions Duett sealing device.
Our Duett sealing device is designed to seal the entire puncture site following
catheterization procedures such as angiography, angioplasty and stenting. We
have received regulatory approvals to market the Duett sealing device in
several international markets, principally in Europe. On June 22, 2000, we
received approval from the FDA of our PMA application for the sale of our Duett
sealing device in the United States. As a result, we very recently commenced
sales of our product in the United States with a direct sales force.

   We have a limited history of operations and have experienced significant
operating losses since inception. As of March 31, 2000, we had an accumulated
deficit of $16.6 million. We commenced international sales in February 1998. To
date, we have generated substantially all of our revenue from sales to
international distributors who resell the device to hospitals.

   Although we have experienced revenue growth in recent periods, this growth
may not be sustainable and, therefore, these recent periods should not be
considered indicative of future performance. We may never achieve significant
revenues or profitability, or if we achieve significant revenues they may not
be sustained in future periods.

Results of Operations

 Three months ended March 31, 2000 compared to three months ended March 31,
 1999

   Net sales increased 210% to $642,545 for the three months ended March 31,
2000 from $207,000 for the three months ended March 31, 1999. This increase in
net sales was the result of increased shipments of the Duett sealing device to
our distributors for sale in Europe. Sales to our German, Norwegian, Italian
and Austrian distributors accounted for approximately 26%, 26%, 18% and 10% of
net sales for the three months ended March 31, 2000.

   Gross profit as a percentage of net sales increased to 46% for the three
months ended March 31, 2000 from 10% for the three months ended March 31, 1999.
This increase as a percentage of net sales resulted from a decrease in cost of
goods sold due to the conversion to the Duett Model 2000 for international
sales in the fourth quarter of 1999 and improved manufacturing processes. Cost
of goods sold consists primarily of direct material component costs, personnel
expenses and manufacturing equipment and overhead related to the production of
our Duett sealing device. The Duett Model 2000 incorporates minor modifications
to the procoagulant components and different vendors for certain components,
resulting in lower cost of goods compared to the original Duett

                                       19
<PAGE>

Model 1000. The approval we recently received from the FDA applies to the Duett
Model 1000. We will not be able to sell the Duett Model 2000 in the United
States until we receive approval of a PMA supplement. We do not expect to
receive FDA approval of a PMA supplement for the Duett Model 2000 prior to
late-2001, at the earliest. We expect gross profit as a percentage of net sales
to continue to increase as we increase our manufacturing volume, improve our
manufacturing processes, and enter the United States market.

   Research and development expenses decreased 3% to $691,723 for the three
months ended March 31, 2000 from $713,271 for the three months ended March 31,
1999. This slight decrease was attributable to the increased absorption of
additional capacity by manufacturing and the transition of the Duett Model 2000
to production. We expect our research and development expenses to increase
through the remainder of 2000 as we hire additional development personnel,
continue work on product improvements and explore new product opportunities.

   Clinical and regulatory expenses decreased 67% to $189,904 for the three
months ended March 31, 2000 from $579,596 for the three months ended March 31,
1999. These expenses consist of payments to clinics for participation in
clinical studies, company personnel related to clinical study administration
and payments to regulatory agencies as part of the product approval process.
The decrease was primarily the result of the completion of our 695-patient
multi-center clinical study in 1999. During the three months ended March 31,
1999, payments related to this clinical study totaled $346,000. We expect our
clinical and regulatory expenses to continue to decrease during the remainder
of 2000 compared to 1999 as additional clinical studies are expected to be
smaller in scope than the multi-center clinical study.

   Sales and marketing expenses increased 157% to $901,315 for the three months
ended March 31, 2000 from $350,065 for the three months ended March 31, 1999.
This increase was due primarily to additional personnel and travel for the
international distribution of our Duett sealing device. We currently anticipate
spending $18.5 million during the period from April 1, 2000 through December
31, 2001 to hire, train and deploy a direct sales force in the United States.
These increases will be principally related to hiring additional sales and
marketing personnel, expanding marketing efforts and training new physicians.

   General and administrative expenses increased 189% to $563,572 for the three
months ended March 31, 2000 from $195,077 for the three months ended March 31,
1999. This increase was primarily attributable to a $235,900 increase in
litigation expenses and $124,900 increase in personnel costs. See Note 11 of
Notes to the Financial Statements. We anticipate that general and
administrative expenses will increase for the foreseeable future as we continue
to add personnel and infrastructure. It is also likely that we will continue to
incur substantial litigation expenses related to patent infringement claims.

   Interest income increased to $121,699 for the three months ended March 31,
2000 from $102,874 for the three months ended March 31, 1999 primarily as a
result of higher cash balances resulting from the exercise of an option and
warrant by an existing investor during the fourth quarter of 1999.

 Year ended December 31, 1999 compared to year ended December 31, 1998

   Net sales increased 189% to $1,429,094 for the year ended December 31, 1999
from $494,150 for the year ended December 31, 1998. This increase in net sales
was the result of increased shipments of our Duett sealing device to our
existing independent international distributors and

                                       20
<PAGE>

shipments to new independent international distributors covering other
territories. International sales of our Duett sealing device commenced in
February 1998. Sales to our German, Norwegian and Italian distributors
accounted for approximately 29%, 20% and 12% of net sales for the year ended
December 31, 1999.

   Gross profit as a percentage of net sales increased to 25% for the year
ended December 31, 1999 from 10% for the year ended December 31, 1998. This
increase as a percentage of net sales resulted from improvements in
manufacturing efficiencies and increases in the number of Duett sealing devices
manufactured.

   Research and development expenses increased 31% to $3,067,897 for the year
ended December 31, 1999 from $2,348,281 in the year ended December 31, 1998.
This increase was attributable to a $301,100 increase for additional personnel
required for the continued development of the Duett sealing device, $240,000 of
materials associated with the development of our next generation sealing device
and $45,900 in prototyping costs.

   Clinical and regulatory expenses decreased 4% to $1,323,972 for the year
ended December 31, 1999 from $1,375,595 for the year ended December 31, 1998.
The decrease was primarily the result of costs associated with the 695-patient
multi-center clinical study of our Duett sealing device which commenced in
August 1998 and was completed in March 1999. In addition to the payments to the
clinical centers for patient enrollment and data collection, we contracted with
a third party to perform data analysis and computation for the study. We also
contracted with a third party to perform a cost outcomes study of the patient
data from this multi-center study.

   Sales and marketing expenses increased 114% to $2,301,603 for the year ended
December 31, 1999 from $1,075,250 for the year ended December 31, 1998. This
increase was due primarily to a $611,500 increase in personnel costs and
$277,800 associated with travel, marketing and physician training for the
international distribution of the Duett sealing device.

   General and administrative expenses increased 185% to $1,903,946 for the
year ended December 31, 1999 from $667,522 in the year ended December 31, 1998.
This increase was primarily the result of $453,500 in initial public offering
costs that were expensed in the fourth quarter of 1999 due to the delay of the
offering and $422,500 in legal expenses in 1999 associated with intellectual
property claims.

   Interest income increased to $371,066 for the year ended December 31, 1999
from $273,877 for the year ended December 31, 1998 primarily as a result of
higher cash balances resulting from our private equity financing completed in
the fourth quarter of 1998.

 Year ended December 31, 1998 compared to the year ended December 31, 1997

   Net sales of $494,150 in 1998 were the result of shipments to international
distributors, with 65% of the sales attributable to our German distributor and
16% of the sales attributable to our Austrian distributor. We commenced
international sales in February 1998 and, accordingly, had no revenues in 1997.

   Gross profit as a percentage of net sales was 10% in 1998. Cost of goods
sold reflected the commencement of manufacturing and assembly operations as
well as manufacturing, engineering and support functions.

                                       21
<PAGE>

   Research and development expenses increased 206% to $2,348,281 in 1998 from
$766,176 in 1997. This increase was attributable to a $577,000 increase
associated with the hiring of additional personnel required to develop our
Duett sealing device, a $146,000 increase in legal costs related to patent
applications and approximately $425,000 of materials associated with the
development of our Duett sealing device.

   Clinical and regulatory expenses increased 430% to $1,375,595 in 1998 from
$259,503 in 1997. The increase was primarily the result of costs associated
with our clinical studies that commenced in January 1998.

   Sales and marketing expenses increased 294% to $1,075,250 in 1998 from
$273,089 in 1997. The increase was due primarily to the international
commercial launch of our Duett sealing device in February 1998, resulting in
increases in costs associated with travel, marketing and physician training.

   General and administrative expenses increased 57% to $667,522 in 1998 from
$425,596 in 1997. The increase was primarily the result of additional
administrative personnel and facilities costs.

   Interest income increased to $273,877 in 1998 from $72,546 in 1997 primarily
as a result of higher cash balances resulting from our December 1997 private
equity financings.

Income Taxes

   We have not generated any pre-tax income to date and therefore have not paid
any federal income taxes since inception in December 1996. No provision or
benefit for federal and state income taxes has been recorded for net operating
losses incurred in any period since our inception.

   As of March 31, 2000, we had $14,585,000 of federal net operating loss
carryforwards available to offset future taxable income which begin to expire
in the year 2013. As of March 31, 2000, we also had federal and state research
and development tax credit carryforwards of $339,000 which begin to expire in
the year 2013. Under the Tax Reform Act of 1986, the amounts of and benefits
from net operating loss carryforwards may be impaired or limited in certain
circumstances, including significant changes in ownership interests. Future use
of our existing net operating loss carryforwards may be restricted due to
changes in ownership or from future tax legislation.

   We have established a valuation allowance against the entire amount of our
deferred tax asset because we have not been able to conclude that it is more
likely than not that we will be able to realize the deferred tax asset, due
primarily to our history of operating losses.

Liquidity and Capital Resources

   We have financed all of our operations since inception through the issuance
of equity securities. Through March 31, 2000, we have sold common stock and
preferred stock generating aggregate net proceeds of $25.4 million. At March
31, 2000, we had $8.1 million in cash and cash equivalents on-hand. During the
three-month period ended March 31, 2000, we used $2.3 million of cash and cash
equivalents in operating activities. The cash used in operating activities was
primarily used to fund our net loss for the period of $1.9 million and
increases in accounts receivable and inventories to support our increased
operations and a decrease in accounts payable as a result of the timing of
certain vendor payments. For the year ended December 31, 1999, we used $7.2
million of cash in

                                       22
<PAGE>

operating activities. This was primarily used to fund our net loss for the
period of $7.9 million and increases in accounts receivable and inventories.
Cash used in operating activities was partially offset by an increase of
$746,000 in accounts payable. Cash used in operating activities for the year
ended December 31, 1998 was $5.2 million. This was primarily used to fund our
net loss for the year of $5.1 million and increases in accounts receivable and
inventories. Our other use of cash in each of these periods was investing
activities to acquire manufacturing and office equipment. Our equipment
acquisitions totaled $159,000 during the three-month period ended March 31,
2000, $316,000 for the year ended December 31, 1999 and $582,000 for the year
ended December 31, 1998.

   We do not have any significant cash commitments related to supply
agreements, nor do we have any commitments for capital expenditures.

   We currently anticipate that we will continue to experience significant
growth in our expenses for the foreseeable future and our expenses will be a
material use of our cash resources. We anticipate that our operating losses
will continue through at least December 31, 2000, because we plan to spend
substantial amounts hiring and training a direct United States sales force,
funding sales and marketing activities and creating and expanding research and
development initiatives. We believe that current cash balances along with cash
generated from the future sales of products and the proceeds of this offering
will be sufficient to meet our operating and capital requirements for at least
the next 12 months. Our liquidity and capital requirements beyond the next 12
months will depend on numerous factors, including the extent to which our Duett
sealing device gains market acceptance and competitive developments.

   If cash generated from operations is insufficient to satisfy our cash needs,
we may be required to raise additional funds. We currently have no commitments
for additional funding and so our ability to meet our long-term liquidity needs
is uncertain. If we raise additional funds through the issuance of equity
securities, our shareholders may experience significant dilution. Furthermore,
additional financing may not be available when needed or, if available,
financing may not be on terms favorable to us or our shareholders. If financing
is not available when required or is not available on acceptable terms, we may
be unable to develop or market our products or take advantage of business
opportunities or respond to competitive pressures.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No.133,
"Accounting for Derivative Instruments and Hedging Activities." This statement
changes the previous accounting definition of derivative which focused on
freestanding contracts, including, for example, options and forwards, and
futures and swaps, expanding it to include embedded derivatives and many
commodity contracts. Under the statement, every derivative is recorded in the
balance sheet as either an asset or liability measured at its fair value. The
statement requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. SFAS
133 is effective for fiscal years beginning after June 15, 1999. We do not
anticipate that the adoption of SFAS 133 will have a material impact on our
financial position or results of operations. We do not currently hold
derivative instruments or engage in hedging activities.

                                    BUSINESS

Overview

   We are a medical device company. We manufacture, market and sell the
Vascular Solutions Duett sealing device, which enables cardiologists and
radiologists to rapidly seal the entire puncture site following catheterization
procedures such as angiography, angioplasty and stenting. A catheterization
procedure involves the insertion of a catheter through a patient's skin and
into an artery to perform minimally invasive medical procedures. In order to
gain access to an artery for a catheter, the artery must first be punctured. At
the end of the procedure, the puncture must be sealed in order to prevent
bleeding. Traditionally, manual compression has been used to seal the puncture
site. Increasingly, vascular sealing devices are used, with three competitors
currently selling FDA-approved devices.

   Our Duett sealing device combines an easy-to-use balloon catheter delivery
mechanism with a biological procoagulant mixture, which we believe offers
advantages over both manual compression and the three other FDA-approved
vascular sealing devices. We began selling our product in Europe in February
1998. On June 22, 2000, we received approval from the FDA of our PMA
application for the sale of the Duett sealing device in the United States. As a
result, we very recently commenced selling our Duett sealing device in the
United States. Over 15,000 Duett sealing devices have been sold and deployed
worldwide. While the vascular sealing device market has developed quickly, it
represents less than 15% of the more than $1 billion potential annual market,
based on the current number of catheterization procedures performed.

   We believe that we are well-positioned to capture a substantial share of the
vascular sealing device market opportunity as our Duett sealing device offers
the following benefits:

  Clinical Benefits

  .  complete closure of the entire puncture site, consisting of the arterial
     puncture and the tissue tract--the tissue between the skin surface and
     the artery;

  .  effective in patients receiving anti-clotting medications, such as
     ReoPro(R), which are increasingly used in therapeutic catheterization
     procedures, through the use of thrombin in our biological procoagulant;

  .  nothing is left behind in the artery to cause an infection or to
     interfere with accessing the site again, if that becomes necessary;

  .  rapid deployment of an easy-to-use, one-size-fits-all device through the
     existing introducer sheath;

  Patient Comfort Benefits

  .  the pain associated with the use of manual compression on the puncture
     site is minimized;

  .  patients are ambulated earlier, thereby minimizing the pain associated
     with immobile bed rest;

  Economic Benefits

  .  the scheduling of patients and utilization of the catheterization
     laboratory can be more efficient due to reduced recovery time and care;
     and

  .  recovery beds and staff can be better utilized through early ambulation
     of patients.

Industry Background

   Over 60 million Americans have one or more types of cardiovascular
disease--diseases of the heart and blood vessels. Cardiovascular disease is
the number one cause of death in the United States and is replacing infectious
disease as the world's pre-eminent health risk. Advances in medicine have
enabled physicians to perform an increasing number of diagnostic and
therapeutic treatments of cardiovascular disease using minimally invasive
methods, such as catheters placed inside the arteries, instead of highly
invasive open surgery. Cardiologists and radiologists use diagnostic
procedures, such as angiography, to confirm, and interventional procedures,
such as angioplasty and stenting, to treat, diseases of the coronary and
peripheral arteries. Based on industry statistics, we estimate that
cardiologists and radiologists performed over seven million diagnostic and
interventional catheterization procedures worldwide in 1999. The number of
catheterization procedures performed is expected to grow by more than 5% each
year for the next three years as the incidence of cardiovascular disease
continues to increase.

   Each procedure using a catheter requires a puncture in an artery, usually
the femoral artery in the groin area, of the patient to gain access for the
catheter, which is deployed through an introducer sheath. Upon removal of the
catheter, the physician must seal this puncture in the artery and the tissue
tract that leads from the skin surface to the artery to stop bleeding. The
traditional method for sealing the puncture site has been a manual process
whereby a healthcare professional applies direct pressure to the puncture
site, sometimes using a sand bag or a large C-clamp, for 20 minutes to an hour
in order to form a blood clot. The healthcare professional then monitors the
patient, who must remain immobile in order to prevent dislodging of the clot,
for an additional four to 48 hours.

   Patients subjected to manual compression generally experience significant
pain and discomfort during compression of the puncture site and during the
period in which they are required to be immobile. Many patients report that
this pain is the most uncomfortable aspect of the catheterization procedure.
In addition, patients usually develop a substantial coagulated mass of blood,
or hemotoma, around the puncture site, limiting patient mobility for up to six
weeks following the procedure. Finally, the need for healthcare personnel to
provide compression and the use of hospital beds during the recovery period
results in substantial costs to the institution which, under virtually all
current healthcare payment systems, are not separately reimbursed.

   In addition to this discomfort and cost, manual compression can result in
major complications at the puncture site. These major complications can
include a pseudo-aneurysm, or the continuation of blood flow from the artery
into the coagulated blood mass at the puncture site, collapse of the femoral
artery or femoral nerve damage from the extended compression. Additional
procedures may be required to correct these major complications.

   The increasing use of medications to prevent blood clot formation during
interventional catheterization procedures has increased the difficulty in
sealing the puncture site using manual compression. During and following the
catheterization procedure, physicians are concerned with the formation of
blood clots in the coronary or peripheral arteries. To prevent clots from
forming, the physician typically administers heparin, an anticoagulant, during
the interventional catheterization procedure. More recently, drugs which
prevent blood clotting by inhibiting platelet aggregation, such as ReoPro(R),
are also being used in interventional catheterization procedures. Because
these platelet inhibitor drugs limit the ability of blood to clot, they also
increase the difficulty of sealing the puncture site using manual compression
and the natural clotting process following the catheterization procedure.

                                      25
<PAGE>

   Until 1996, manual compression was used following virtually all
catheterization procedures. In late 1995, the first vascular sealing device
which did not rely on compression was introduced in the United States. In
addition to the Duett sealing device, three devices have received FDA approval
and are currently being marketed around the world.

  .  One device places a dry collagen plug in the tissue tract adjacent to
     the puncture in the artery. The plug seals the tissue tract, however,
     the clotting effect of collagen at the puncture in the artery is
     limited, particularly if anticoagulants or platelet inhibitors are
     present in the bloodstream. As a result, manual pressure may be required
     for an additional period of time in order to achieve closure of the
     puncture in the artery.

  .  The second device inserts a collagen plug into the tissue tract
     connected by a suture to a biodegradable anchor which is inserted into
     the artery. This device is held in place for approximately 20 minutes to
     seal the puncture in the artery. The presence of the anchor prohibits
     reaccess to the puncture site for up to 90 days. The reliance on
     collagen as the clotting agent limits the effectiveness of this device
     in patients being treated with anticoagulants or platelet inhibitors.

  .  The third device is a mechanical device that employs remotely controlled
     needles to suture the puncture in the artery but leaves the tissue tract
     unsealed. The non-absorbable suture permanently remains at the arterial
     puncture. This device is more complicated to learn and use than the
     collagen-based devices.

   In aggregate, $160 million of these three FDA-approved devices were sold
worldwide in 1999 compared to less than $20 million in 1996. Based on the
number of catheterization procedures performed annually by cardiologists and
radiologists, industry sources report that the total market opportunity for
vascular sealing devices is more than $1 billion. Accordingly, the market
opportunity for vascular sealing devices is less than 15% penetrated.

The Vascular Solutions Duett Sealing Device

   We believe our product (1) offers a complete seal of the puncture site with
nothing left behind in the artery, (2) is an easy-to-use system and (3)
minimizes patient discomfort and permits early ambulation. Our product uses a
balloon catheter, a device already familiar to cardiologists and radiologists,
which is inserted through the introducer sheath that is already in the patient.
The inflated balloon serves as a temporary mechanical seal, preventing the flow
of blood from the artery. Our biological procoagulant, which is a proprietary
mixture of collagen, thrombin and diluent, is then delivered to the puncture
site, stimulating rapid clotting and creating a complete seal of both the
arterial puncture and the tissue tract from the artery to the skin surface. The
blood-clotting speed and strength of thrombin enable the use of the Duett
sealing device even in the presence of powerful anti-clotting medications, such
as ReoPro(R), increasingly used in interventional catheterization procedures.
With our Duett sealing device, nothing is left behind in the artery, so
immediate reaccess of the site, if necessary, is possible, and the potential
for infection is minimized.

Business Strategy

   Our primary objective is to establish our Duett sealing device as the
leading product in the rapidly growing vascular sealing device market. The key
steps in achieving our primary objective are the following:


                                       26
<PAGE>

  .  Hire, Train and Deploy a Direct Sales Force in the United States. We
     very recently commenced sales of our Duett sealing device in the United
     States through a direct sales force that includes clinical specialists
     who train interventional cardiologists, radiologists and catheterization
     laboratory administrators on the use of our product. We believe that
     effective training is a key factor in promoting use of our Duett sealing
     device. We have created and will continue to work to improve an in-the-
     field training and certification program for the use of our Duett
     sealing device. We have hired our initial United States direct sales
     force consisting of 28 employees, which we expect to grow to
     approximately 60 employees by the end of 2001. We currently anticipate
     spending approximately $18.5 million during the period from April 1,
     2000 through December 31, 2001 to hire, train and deploy our direct
     sales force.

  .  Promote the Duett Sealing Device's Benefits Compared to Manual
     Compression and Other Devices. We believe that the primary benefits of
     the Duett sealing device are improved patient outcomes and provider
     efficiencies. We intend to use our existing and growing body of clinical
     results to initiate use of our Duett sealing device by physicians
     currently using manual compression and to convert physicians from other
     vascular sealing devices to our product. Through our marketing staff, we
     plan on building market awareness of our Duett sealing device using a
     wide range of programs, materials and events, including conference and
     trade show appearances and the dissemination of sales literature and
     promotional materials.

  .  Capitalize on the Large and Growing Vascular Sealing Market. While the
     market for vascular sealing devices has developed quickly, it represents
     less than 15% of the more than $1 billion potential annual market, based
     on the current number of catheterization procedures performed. The
     primary factors underlying the market opportunity for vascular sealing
     devices are the significant and growing number of catheterization
     procedures being performed and the substantial majority of the resulting
     puncture sites still being sealed through manual compression. The growth
     in catheterization procedures by cardiologists and radiologists reflects
     an increasing incidence of cardiovascular disease and the growing number
     of catheterization laboratories worldwide. In 1999, over seven million
     catheterization procedures were performed. This number is expected to
     increase by more than 5% each year for the next three years. Although
     the market for vascular sealing devices has grown rapidly, over 85% of
     the arterial punctures in 1999 were sealed using manual compression. We
     believe that our device offers benefits that position it well to capture
     a significant share of the market for vascular sealing devices.

  .  Develop Duett Sealing Product Line Extensions and Explore New Product
     Opportunities. In addition to developing next generation versions of our
     Duett sealing device, we are evaluating enhancements that will allow our
     product to be used in interventional procedures that result in larger
     arterial punctures that are greater than nine French or three
     millimeters in diameter. Furthermore, we intend to leverage our
     knowledge and experience in the vascular sealing market into other
     interventional cardiology and radiology products.

Clinical Results

   To date, over 15,000 deployments of our Duett sealing device have been
performed worldwide. A total of 31 scientific publications and presentations
have been made on our Duett sealing device at interventional cardiology and
radiology meetings, reporting the results of over 2,500 deployments.

   Six separate clinical studies of our Duett sealing device have been
performed to date, each of which produced very favorable clinical results.

   The Simple and Effective Arterial cLosure ("SEAL") clinical study was a
randomized, controlled study to support our PMA application with the FDA. In
the SEAL study, the Duett sealing device demonstrated, as compared to manual
compression, the three primary endpoints of (1) reduced time to the cessation
of bleeding, (2) reduced time to ambulation of the patient and (3) no
statistically significant increase in major complications.

Sales, Marketing and Distribution

   Our international sales and marketing strategy has been to sell to
interventional cardiologists and radiologists through established independent
distributors in major international markets, subject to required regulatory
approvals. Our Duett sealing device is currently marketed through independent
distributors in Germany, Norway, Italy, Austria, the United Kingdom, Denmark,
Switzerland, Finland, Sweden, Greece, Belgium, Spain, the Netherlands, Taiwan
and Hong Kong. We intend to add independent distributors in other countries as
our sales and marketing efforts are expanded. Under multi-year written
distribution agreements with each of our independent distributors, we ship our
Duett sealing device to these distributors upon receipt of purchase orders.
Each of our independent distributors has the exclusive right to sell our Duett
sealing device within a defined territory. These distributors also market other
medical products, although they have agreed not to sell other vascular sealing
devices. Our independent distributors purchase our Duett sealing device from us
at a discount from list price and resell the device to hospitals and clinics.
Sales to international distributors are denominated in United States dollars.
The end-user price is determined by the distributor and varies from country to
country.

   Substantially all of our revenues through March 31, 2000 were derived from
sales to international distributors, primarily in Europe, none of which is
affiliated with us. Sales in Europe constituted 90% and 97% of our net sales
for the year ended December 31, 1999 and the three months ended March 31, 2000.
Sales to Cardiologic G.m.b.H., our German distributor, accounted for 29% of our
net sales for the year ended December 31, 1999. Sales to MicroMed A.S., our
Norwegian distributor, accounted for 20% of net sales and sales to N.G.C.
Medical S.p.A., our Italian distributor, accounted for 12% for the same period.
Sales to our German, Norwegian, Italian and Austrian distributors accounted for
approximately 26%, 26%, 18% and 10% of net sales for the three months ended
March 31, 2000. Our Austrian distributor is EuroMed.

   Upon receipt of FDA approval of our PMA application on June 22, 2000, we
commenced sales of our Duett sealing device in the United States through our
direct sales organization. We have hired our initial direct sales force
consisting of 28 employees, which we expect to grow to approximately 60
employees by the end of 2001. We believe that the majority of interventional
catheterization procedures in the United States are performed in high volume
catheterization laboratories, and that these institutions can be served by our
focused direct sales force. While we intend to initially focus

                                       28
<PAGE>

on these high volume laboratories, we believe that our Duett sealing device's
ease of use and relatively short training time will also make our product
attractive to lower volume laboratories.

   As part of our sales force, we have hired clinical specialists to train
physicians and other healthcare personnel on the use of the Duett sealing
device. We believe that effective training is a key factor in encouraging
physicians to use our Duett sealing device. We have created, and will continue
to work to improve an in-the-field training and certification program for the
use of our Duett sealing device. We will seek to develop and maintain close
working relationships with our customers to continue to receive input
concerning our product development plans.

   We are focused on building market awareness and acceptance of our Duett
sealing device. Our marketing organization provides a wide range of programs,
materials and events that support our sales force. These include product
training, conference and trade show appearances and sales literature and
promotional materials. Members of our medical advisory board also aid in
marketing our Duett sealing device by publishing articles and making
presentations at physicians' meetings and conferences.

Product Technology

   The components of our proprietary Duett sealing device consist of a very
thin balloon catheter and a procoagulant mixture. The balloon catheter consists
of a balloon made of polyethylene connected to a wire, covered by a sleeve. The
procoagulant is a proprietary mixture of collagen, thrombin and a diluent. Both
collagen and thrombin have been approved for use as blood clotting agents in
the human body by the FDA for over ten years. The mixture of thrombin, a very
rapid blood clotting agent, and collagen, which allows the procoagulant to
assume a gel-like viscosity, provides a highly effective clotting agent when
delivered directly to the puncture site. The diluent is a liquid used to create
the desired viscosity and neutralize the pH of the mixture. The procoagulant is
mixed before use and the Duett sealing device is deployed in the following
steps:

                               Introducer Sheath

   The Duett catheter can be deployed through any commonly used introducer
sheath from five French to nine French in diameter. Therefore, the sheath that
is already in the femoral artery is left in place and no replacement of the
sheath is required.

   The Duett catheter is then inserted through the introducer sheath and into
the femoral artery and the syringe containing the Duett procoagulant is
attached to the sidearm of the introducer sheath.

                         Inflated Duett Baloon Catheter

   Using a syringe, the balloon is inflated and positioned against the inner
surface of the artery where the arterial pressure and gentle traction result in
the balloon acting as a temporary seal of the puncture.

                             Procoagulant Delivery

   Next, the procoagulant is delivered directly to the top of the arterial
puncture and the tissue tract through the sidearm of the introducer sheath. The
procoagulant stimulates rapid clotting through the powerful action of thrombin
and collagen. The introducer sheath is removed from the body as the
procoagulant agent is being delivered.

                             Duett Catheter Sleeve

   Immediately after the delivery of the procoagulant to the tissue tract, the
balloon is deflated and covered by the sleeve. The slippery nature of the
sleeve as well as its low profile (approximately one millimeter in diameter)
allows for removal of the balloon catheter from the artery without disruption
of the procoagulant.

         [Schematic drawing of artery labeling the item listed below:]

                         Complete Seal of puncture Site

   After removal of the Duett catheter from the artery, manual pressure is
maintained for a short time, usually two to five minutes, to assure the seal.
We recommend ambulation of patients generally one to two hours after diagnostic
catheterizations and two to four hours after interventional catheterization
procedures.

Research and Development

   Our research and development staff is currently focused on improving our
Duett sealing device and reducing our cost of goods sold. We incurred expenses
of $2,348,281 in 1998 and $3,067,897 in 1999 for research and development
activities. To further reduce our costs, our research and development group is
in the process of developing the in-house capability to manufacture some of the
components currently produced by outside vendors.

   We intend to research and develop new sealants in the future for use in our
Duett sealing device as well as to apply our core closure technology to other
catheterization procedures, including cardio-pulmonary support procedures,
treatment of abdominal aortic aneurysms and treatment of pseudo-aneurysms. The
large size of the punctures in these procedures makes closure of the puncture
site very difficult using conventional compression methods. We believe that
modifications of our delivery system will allow our sealing technology to be
useful in larger punctures of the femoral artery that are greater than nine
French, as well as in cases of abnormalities such as pseudo-aneurysms.

   We expect our research and development activities to expand to include
evaluation of new concepts and products beyond vascular sealing in the
interventional cardiology and radiology field. We believe that there are many
potential new interventional products that would fit within the development,
clinical, manufacturing and distribution network we have created for our Duett
sealing device.

Manufacturing

   We manufacture our Duett sealing device in our facility in a suburb of
Minneapolis, Minnesota. The catheter manufacturing and packaging processes
occur under a controlled clean room environment. Our manufacturing facility and
processes were certified in July 1998 as compliant with the European
Community's ISO 9001 standards and was audited in September 1999 for compliance
with the FDA's good manufacturing practices with no deficiencies noted.

   We purchase components from various suppliers and rely on single sources for
several parts of the Duett sealing device. In September 1998, we entered into a
ten year, sole-source, supply

                                       32
<PAGE>

agreement with our collagen supplier, Davol Inc., that provides for a fixed
price based on volume purchases which is adjusted annually for increases in the
Department of Labor's employer's cost index. In June 1999, we entered into a
five year, sole-source, supply agreement with our thrombin supplier, GenTrac,
Inc., a subsidiary of Jones Pharma, Incorporated, that provides for a fixed
price with a price adjustment formula based on increased costs and wholesale
price increases. To date, we have not experienced any significant adverse
effects resulting from shortages of components.

   The manufacture and sale of our Duett sealing device entail significant risk
of product liability claims. Although we have product liability insurance
coverage in an amount which we consider reasonable, it may not be adequate to
cover potential claims. Any product liability claims asserted against us could
result in costly litigation, reduced sales and significant liabilities and
divert the attention of our technical and management personnel away from the
development and marketing of the Duett sealing device for significant periods
of time.

Competition

   Competition in the vascular sealing market is intense, and we believe that
it will increase. We believe that the primary bases of competition in the
vascular sealing market are clinical efficacy, ease of use, patient comfort,
minimization of complications and cost-effectiveness. On these bases, we
believe that our product is well-positioned.

   Because the substantial majority of vascular sealing is performed through
manual compression, this represents our primary competition. Manual compression
usually requires a healthcare professional to manually apply pressure to the
puncture site for 20 minutes to one hour following which the patient is
confined to bed rest for between four and 48 hours. Often manual compression
involves the use of mechanical devices, including C-clamps and sandbags, or
pneumatic devices. Manual compression is considered to be uncomfortable for the
patient.

   Our Duett sealing device also competes with three vascular sealing devices,
none of which had over 40% of the vascular sealing device market in 1999. These
three competitive devices are:

  .  The VasoSeal device, manufactured and marketed by Datascope Corp., seals
     the tissue tract by placing a dry collagen plug in the tissue tract
     adjacent to the puncture in the artery.

  .  The Angio-Seal device, sold by the Daig division of St. Jude Medical,
     Inc. and developed by Kensey Nash Corporation, seals the puncture site
     through the use of a collagen plug on the outside of the artery
     connected by a suture to a biodegradable anchor which is inserted into
     the artery.

  .  The third device, developed and marketed under the ProStar(TM),
     TechStar(TM) and Closer(TM) names by Perclose, Inc., a subsidiary of
     Abbott Laboratories, seals the puncture site through the use of a
     mechanical device that enables a physician to perform a minimally
     invasive replication of open surgery.

   We believe that several other companies are developing arterial closure
devices, however, we are unaware of any new sealing device or company that has
entered U.S. clinical studies. The medical device industry is characterized by
rapid and significant technological change as well as the frequent emergence of
new technologies. There are likely to be research and development projects
related to vascular sealing devices of which we are currently unaware. A new
technology or product may emerge that results in a reduced need for vascular
sealing devices or results in a product that renders our product
noncompetitive.

Regulatory Requirements

 United States

   Our Duett sealing device is regulated in the United States as a medical
device by the FDA under the FDC Act, and required premarket approval by the FDA
prior to being sold. In May 1997, the FDA determined that the review of the
Duett sealing device would be delegated to the Center for Devices and
Radiological Health area of the FDA, with a consulting review by the Center for
Biologic Evaluation and Research. During 1998 and 1999, we received approval of
our investigational device exemption, or IDE, application to start our
feasibility clinical study, filed our IDE Supplement to begin our multi-center
clinical study, completed the SEAL multi-center clinical study and filed our
PMA application with the FDA. In September 1999 our manufacturing facility was
audited by the FDA, with no deficiencies or non-compliances noted by the
inspector. In December 1999, we received the FDA's review letter of our PMA
application, and we submitted an amendment to our PMA to the FDA in January
2000. On June 22, 2000, we received approval from the FDA of our PMA
application to sell the Duett sealing device in the United States.

   The FDA classifies medical devices into one of three classes based upon
controls the FDA considers necessary to reasonably ensure their safety and
effectiveness. Class I devices are subject to general controls such as
labeling, premarket notification and adherence to good manufacturing practices.
Class II devices are subject to the same general controls and also are subject
to special controls such as performance standards, postmarket surveillance,
patient registries and FDA guidelines, and may also require clinical testing
prior to approval. Class III devices are subject to the highest level of
controls because they are used in life-sustaining or life-supporting
implantable devices. Class III devices require rigorous clinical testing prior
to their approval. Our Duett sealing device is classified as a Class III
device.

   Manufacturers must file an IDE application if human clinical studies of a
device are required and if the device presents what the FDA considers to be a
significant risk. The IDE application must be supported by data, typically
including the results of animal and mechanical testing of the device. If the
IDE application is approved by the FDA, human clinical studies may begin at a
specific number of investigational sites with a maximum number of patients, as
approved by the FDA. The clinical studies must be conducted under the review of
an independent institutional board at the hospital performing the clinical
study. Our Duett sealing device is subject to the IDE requirements. We received
approval of our IDE application and performed our feasibility clinical study at
two United States centers in January to March 1998. Based on the results of
this feasibility clinical study, we received approval and performed our 695
patient multi-center SEAL clinical study from August 1998 through March 1999.

   Generally, upon completion of these human clinical studies, a manufacturer
seeks approval of a Class III medical device from the FDA by submitting a PMA
application. A PMA application must be supported by extensive data, including
the results of the clinical studies, as well as literature to establish the
safety and effectiveness of the device. The FDA allowed us to submit our PMA
application in segments prior to completion of our clinical studies. Upon
completion of the follow up and data analysis of the SEAL clinical study, we
submitted the final two segments of our PMA application to the FDA in June
1999. Under the FDC Act, the FDA has 180 days to review a PMA application,
although the review of such an application more often occurs over a longer time
period and may require additional information. In December 1999, we received
the FDA's review letter of our PMA application, and we submitted an amendment
to our PMA to the FDA in January 2000. On June 22, 2000, we received approval
from the FDA of our PMA application for the sale of the Duett sealing device in
the United States. Our PMA approval was conditioned on our agreeing to

                                       34
<PAGE>

perform a post approval study of the immunogenic response to the Duett
procoagulant and a post approval animal study of the 30 day resorbtion of the
Duett procoagulant, both of which we agreed to conduct and intend to complete
by the end of 2000. In our worldwide clinical experience to date, we have not
observed any evidence of elevated immunogenic response to the Duett
procoagulant or any substantial infections caused by the resorbtion of the
Duett procoagulant. Nevertheless, the FDA or international regulatory agencies
could restrict or withdraw their approval of our Duett sealing device if one of
the post approval studies produces adverse results that would support such an
action.

   We also are subject to FDA regulations concerning manufacturing processes
and reporting obligations. These regulations require that manufacturing steps
be performed according to FDA standards and in accordance with documentation,
control and testing standards. We also are subject to inspection by the FDA on
an on-going basis. We are required to provide information to the FDA on adverse
incidents as well as maintain a documentation and record keeping system in
accordance with FDA guidelines. The advertising of the Duett sealing device
also is subject to both FDA and Federal Trade Commission jurisdiction. If the
FDA believes that we are not in compliance with any aspect of the law, it can
institute proceedings to detain or seize products, issue a recall, stop future
violations and assess civil and criminal penalties against us, our officers and
our employees.

 International

   The European Union has adopted rules which require that medical products
receive the right to affix the CE mark, an international symbol of adherence to
quality assurance standards and compliance with applicable European medical
device directives. As part of the CE compliance, manufacturers are required to
comply with the ISO 9000 series of standards for quality operations. We
received the CE mark approval for our Duett sealing device and ISO 9001
certification in July 1998.

   International sales of the Duett sealing device are subject to the
regulatory requirements of each country in which we sell our product. These
requirements vary from country to country but generally are much less stringent
than those in the United States. Our Duett sealing device is currently marketed
in Germany, Norway, Italy, Austria, the United Kingdom, Denmark, Switzerland,
Finland, Sweden, Greece, Belgium, Spain, the Netherlands, Taiwan and Hong Kong.
We have obtained regulatory approvals where required. Through our Japanese
distributor, we are pursuing the regulatory approval for commercial sale in
Japan.

Third Party Reimbursement

   In the United States, healthcare providers that purchase medical devices,
such as vascular sealing devices, generally rely on third-party payors,
principally the Health Care Financing Administration, or HCFA, and private
health insurance plans, to reimburse all or part of the cost of therapeutic and
diagnostic catheterization procedures. We believe that in the current United
States reimbursement system, the cost of vascular sealing devices is
incorporated into the overall cost of the catheter procedure.

   We are working to establish the cost benefit of the Duett sealing device,
relying on shortened hospital stays and decreased use of healthcare
professionals, to justify the increased cost of using our Duett sealing device
in the United States. As part of our 695-patient, 15-center SEAL clinical
study, we retained the Emory Cost Outcomes Research Center to perform an
analysis of the costs and benefits of the use of the Duett sealing device in a
randomized, controlled comparison to manual compression. Using the results of
this study, we believe that we are able to demonstrate that the use of our
Duett sealing device can result in cost savings in healthcare personnel and
hospital resources.

                                       35
<PAGE>

   The Health Care Financing Administration is in the process of implementing a
new Medicare prospective payment system for hospital outpatient services,
scheduled to be effective on August 1, 2000. One aspect of the new system
involves the recognition of new technology items and services as discrete
payment groups under the prospective payment system. Under this new system,
hospitals will receive separate payments for the use of new medical devices
that are recognized by HCFA. Two competitive vascular sealing devices have
recently received recognition as new technology items and a discrete payment
group. With our recent receipt of FDA approval, we are applying for the same
recognition for our Duett sealing device. The next date for inclusion of new
technology items by HCFA is October 1, 2000.

   Market acceptance of the Duett sealing device in international markets is
dependent in part upon the availability of reimbursement from healthcare
payment systems. Reimbursement and healthcare payment systems in international
markets vary significantly by country. The main types of healthcare payment
systems in international markets are government sponsored healthcare and
private insurance. Countries with government sponsored healthcare, such as the
United Kingdom, have a centralized, nationalized healthcare system. New devices
are brought into the system through negotiations between departments at
individual hospitals at the time of budgeting. In most foreign countries, there
are also private insurance systems that may offer payments for alternative
therapies.

   We have pursued reimbursement for our Duett sealing device internationally
through our independent distributors. We have initially focused on the markets
of Germany, Austria, Switzerland, Norway, Denmark, Finland, Sweden, Belgium,
Spain, Greece, the Netherlands, the United Kingdom, Taiwan, Italy and Hong
Kong. While the healthcare financing issues in these countries are substantial,
we have been able to sell the Duett sealing device to private clinics or
nationalized hospitals in each of these countries.

Patents and Intellectual Property

   We file patent applications to protect technology, inventions and
improvements that are significant to the development of our business, and use
trade secrets and trademarks to protect other areas of our business.

   Prior to the formation of our company, Dr. Gary Gershony filed a number of
patent applications in the United States and other countries directed to
proprietary technology used in our Duett sealing device. Upon the commencement
of our operations in February 1997, Dr. Gershony assigned all patents and
patent applications relating to the Duett sealing device to us on a worldwide,
perpetual, royalty-free basis. At the time of assignment, there existed one
United States patent issued that is directed to a balloon catheter sealing
device and method and which expires in May 2013, three United States patents
pending and an international patent application pending which designated
numerous foreign countries and regions.

   Since commencing operations, we have continued the prosecution of the
pending United States patent applications and filed new patent applications. A
second United States patent has issued that is directed to a balloon catheter
and procoagulant sealing device and method and which expires in October 2015. A
third United States patent has also issued that contains method claims
concerning the use of a balloon catheter and flowable procoagulant and which
expires in October 2015. A fourth United States patent has issued concerning
the procoagulant mixture and which expires in October 2015. A fifth United
States patent has issued concerning a balloon catheter sealing device and which
expires in May 2013. Finally, a sixth United States patent has issued
concerning a balloon catheter and procoagulant sealing device and which expires
in October 2015. We currently have six additional

                                       36
<PAGE>

United States patents pending concerning aspects of our Duett sealing device
and other interventional products. We also have pursued international patent
applications, which designate the key developed nations with substantive patent
protection systems.

   The interventional cardiology market in general, and the vascular sealing
device field in particular, is characterized by numerous patent filings and
frequent and substantial intellectual property litigation. Each of the three
vascular sealing products with which our Duett sealing device competes has been
subject to infringement litigation. We are aware of many United States patents
issued to other companies in the vascular sealing field which describe vascular
sealing devices. After consultation with our intellectual property counsel, we
believe that our Duett sealing device does not infringe any of these existing
United States issued patents. The interpretation of patents, however, involves
complex and evolving legal and factual questions. Intellectual property
litigation in recent years has proven to be complex and expensive, and the
outcome of such litigation is difficult to predict.

   On July 23, 1999, we were named as the defendant in a patent infringement
lawsuit brought by Datascope Corp. in the United States District Court for the
District of Minnesota. The complaint requested a judgment that our Duett
sealing device infringes and, following FDA approval will infringe, a United
States patent held by Datascope and asks for relief in the form of an
injunction that would prevent us from selling our product in the United States
as well as an award of attorneys' fees, costs and disbursements. On March 15,
2000, the court granted summary judgment dismissing all of Datascope's claims,
subject to the right of Datascope to recommence the litigation after our
receipt of FDA approval of our Duett sealing device. On July 12, 2000, after
our receipt of FDA approval, Datascope recommenced this litigation, alleging
that the Duett sealing device infringes a United States patent held by
Datascope and requesting relief in the form of an injunction that would prevent
us from selling our product in the United States, damages caused by our alleged
infringement, and other costs, disbursements and attorneys' fees. We believe
the allegations included in the complaint are without merit, and we intend to
defend this litigation vigorously. It is not possible to predict the timing or
outcome of the Datascope litigation, including whether we will be prohibited
from selling our Duett sealing device in the United States or internationally,
or to estimate the amount or range of potential loss, if any.

   On September 22, 1999, we received a letter from the Daig division of St.
Jude Medical, Inc. claiming that the manufacture, use, marketing and sale of
our Duett sealing device infringes upon certain United States patents licensed
by Daig. The letter referenced a prior letter dated August 18, 1998 from us to
the prior licensee of those patents in which we made a proposal intended to
avoid the anticipated litigation over those patents. The proposed license was
rejected. On July 3, 2000, we were named as the defendant in a patent
infringement lawsuit brought by St. Jude Medical and Daig in the United States
District Court for the District of Minnesota. The complaint requests a judgment
that our Duett sealing device infringes a series of four patents held by St.
Jude Medical and asks for relief in the form of an injunction that would
prevent us from selling our product in the United States, damages caused by the
manufacture and sale of our product, and other costs, disbursements and
attorneys' fees. We have previously consulted with our intellectual property
counsel regarding St. Jude Medical's United States patents and do not believe
that we infringe them. We believe the allegations included in the complaint are
without merit, and we intend to defend this litigation vigorously. It is not
possible to predict the timing or outcome of the St. Jude Medical litigation,
including whether we will be prohibited from selling our Duett sealing device
in the United States or internationally, or to estimate the amount or range of
potential loss, if any.

                                       37
<PAGE>


   We may become the subject of additional intellectual property claims in the
future related to our Duett sealing device. Our defense of the Datascope claim,
the St. Jude Medical claim and any other intellectual property claims filed in
the future, regardless of the merits of the complaint, could divert the
attention of our technical and management personnel away from the development
and marketing of the Duett sealing device for significant periods of time. The
costs incurred to defend the Datascope claim, the St. Jude Medical claim and
other future claims could be substantial and adversely affect us, even if we
are ultimately successful. An adverse determination in the Datascope matter,
the St. Jude Medical matter or in other litigation or interference proceedings
in the future could prohibit us from selling our product, subject us to
significant liabilities to third parties or require us to seek licenses from
third parties.

   We also rely on trade secret protection for certain aspects of our
technology. We typically require our employees, consultants and vendors for
major components to execute confidentiality agreements upon their commencing
services with us or before the disclosure of confidential information to them.
These agreements generally provide that all confidential information developed
or made known to the other party during the course of that party's relationship
with us is to be kept confidential and not disclosed to third parties, except
in special circumstances. The agreements with our employees also provide that
all inventions conceived or developed in the course of providing services to us
shall be our exclusive property.

   We also intend to register the trademarks and trade names through which we
conduct our business. To date, we have applied for registration in the United
States of the mark "Vascular Solutions Duett" and the Duett logo.

Facilities

   Our principal offices are in approximately 24,000 square feet of leased
space in a suburb of Minneapolis, Minnesota. These facilities include
approximately 8,200 square feet used for manufacturing activities,
approximately 3,300 square feet used for research and laboratory activities,
with the remainder used for administrative offices. Our lease for these
facilities expires March 31, 2003 and includes both an option to renew for an
additional five-year term and an option to terminate after April 1, 2001. We
believe that these facilities will be adequate to meet our needs through at
least the end of 2000.

Employees

   As of June 1, 2000, we had 86 full time employees. Of these employees, 30
were in manufacturing activities, 30 were in sales and marketing activities,
seven were in research and development activities, eight were in regulatory,
quality assurance and clinical research activities and 11 were in general and
administrative functions. We have never had a work stoppage and none of our
employees are covered by collective bargaining agreements. We believe our
employee relations are good.

Legal Proceedings

   On July 23, 1999, we were named as the defendant in a patent infringement
lawsuit brought by Datascope Corp. in the United States District Court for the
District of Minnesota. The complaint requested a judgment that our Duett
sealing device infringes and, following FDA approval will infringe, a United
States patent held by Datascope and asks for relief in the form of an
injunction that would prevent us from selling our product in the United States
as well as an award of attorneys' fees, costs and disbursements. On August 12,
1999, we filed our answer to this lawsuit and brought a

                                       38
<PAGE>


counterclaim alleging unfair competition and tortious interference. On August
20, 1999, we moved for summary judgement to dismiss Datascope's claims. On
March 15, 2000, the court granted summary judgment dismissing all of
Datascope's claims, subject to the right of Datascope to recommence the
litigation after our receipt of FDA approval of our Duett sealing device. On
July 12, 2000, after our receipt of FDA approval, Datascope recommenced this
litigation, alleging that the Duett sealing device infringes a United States
patent held by Datascope and requesting relief in the form of an injunction
that would prevent us from selling our product in the United States, damages
caused by our alleged infringement, and other costs, disbursements and
attorneys' fees. We believe the allegations included in the complaint are
without merit, and we intend to defend this litigation vigorously. It is not
possible to predict the timing or outcome of the Datascope litigation,
including whether we will be prohibited from selling our Duett sealing device
in the United States or internationally, or to estimate the amount or range of
potential loss, if any.

   On September 22, 1999, we received a letter from the Daig division of St.
Jude Medical, Inc. claiming that the manufacture, use, marketing and sale of
our Duett sealing device infringes upon certain United States patents licensed
by Daig. The letter referenced a prior letter dated August 18, 1998 from us to
the prior licensee of those patents in which we made a proposal intended to
avoid the anticipated litigation over those patents. The proposed license was
rejected. On July 3, 2000, we were named as the defendant in a patent
infringement lawsuit brought by St. Jude Medical and Daig in the United States
District Court for the District of Minnesota. The complaint requests a judgment
that our Duett sealing device infringes a series of four patents held by St.
Jude Medical and asks for relief in the form of an injunction that would
prevent us from selling our product in the United States, damages caused by the
manufacture and sale of our product, and other costs, disbursements and
attorneys' fees. We have previously consulted with our intellectual property
counsel regarding St. Jude Medical's United States patents and do not believe
that we infringe them. We believe the allegations included in the complaint are
without merit, and we intend to defend this litigation vigorously. It is not
possible to predict the timing or outcome of the St. Jude Medical litigation,
including whether we will be prohibited from selling our Duett sealing device
in the United States or internationally, or to estimate the amount or range of
potential loss, if any.

   Other than the Datascope and St. Jude Medical claims, there are no legal
proceedings pending against us.

Benefit Plans

 Stock Option and Stock Award Plan

   Our stock option and stock award plan was approved by our board of directors
and shareholders and provides for the granting of the following to employees
and non-employees of Vascular Solutions:

  .  stock options, including incentive stock options and non-qualified stock
     options;

  .  stock appreciation rights; and

  .  restricted stock.

   We have reserved 1,400,000 shares of common stock for issuance under the
stock option and stock award plan. The stock option and stock award plan was
amended in February 2000 to provide for an automatic annual increase in the
number of shares available under the plan, beginning in 2001 and ending in
2006, equal to the lesser of:

  .  500,000 shares;

  .  5% of the common-equivalent shares outstanding at the end of the prior
     fiscal year; or

  .  a smaller amount determined by the board of directors or the committee
     administering the plan.

The application of these automatic annual increase provisions will result in a
maximum total authorized pool of 4,400,000 shares.

   The plan is administered by the compensation committee of the board of
directors. The committee has the discretion to select the optionees and
grantees and to establish the terms and conditions of each stock option and
award, subject to the provisions of the plan. The exercise price for an
incentive stock option granted under the plan must not be less than the fair
market value of our common stock on the date the option is granted. The
exercise price of a non-qualified option granted under the plan must not be
less than 50% of the fair market value of our common stock on

                                       45
<PAGE>

the date the option is granted. The term of each incentive stock option is
determined by the committee but may not exceed ten years from the date the
option is granted. Options may be exercised by tendering cash, by tendering
shares of our common stock already owned by the optionee or, in the discretion
of the committee, by the issuance of a promissory note. The plan may be amended
or discontinued by our board of directors at any time.

   In connection with any option granted under the plan, the committee may
grant a stock appreciation right. A stock appreciation right is a right to
receive, in lieu of the exercise of an option, the difference between the fair
market value of the common stock subject to the option and the exercise price
of the option. A stock appreciation right may be exercised as an alternative,
but not in addition to, the exercise of the option. A stock appreciation right
may be paid in cash or shares of our common stock, in the discretion of the
committee. The committee has not granted any stock appreciation rights.

   The stock option and stock award plan also permits the award of restricted
stock to employees or non-employees who perform valuable services for us.
Restricted stock awards are a grant to an individual of a fixed number of
shares of our common stock which vest over a specific period of time. The
committee has the authority to determine the amount of any award and the
conditions and timing of the vesting of the shares. No restricted stock awards
have been made.

   The stock option and stock award plan also provides for the automatic grant
to each director who is not also our employee an option to purchase 10,000
shares of our common stock upon first being elected as a member of the board of
directors and additional options to purchase 10,000 shares of common stock at
each annual meeting of shareholders at which the director is re-elected. The
exercise price of the options granted to directors under the stock option and
stock award plan is equal to the fair market value of the common stock on the
date of grant. The options expire upon the earlier of ten years from the date
of grant or the date the director no longer serves on the board of directors.
All options granted to non-employee directors under the stock option and stock
award plan are nonqualified stock options.

   As of June 1, 2000, options to purchase an aggregate of 950,211 shares of
common stock, at an average exercise price of $4.41 per share, were outstanding
under the stock option and stock award plan and a total of 331,029 shares were
available for future option grants.

 Employee Stock Purchase Plan

   Our employee stock purchase plan was adopted by the board of directors in
May 2000 and we intend to submit the plan to our shareholders for approval at
our annual meeting in March 2001. If the shareholders do not approve the
employee stock purchase plan, it will be terminated and all contributions
returned to the participants without the purchase of any shares. A total of
500,000 shares of common stock were reserved for issuance under the employee
stock purchase plan, none of which have been issued as of the date of this
offering. The number of shares authorized and reserved for issuance under the
employee stock purchase plan will be subject to an automatic annual increase on
the first day of each of our fiscal years beginning in 2002, equal to the
lesser of:

  .  200,000 shares;

  .  2% of our outstanding common stock on the last day of the immediately
     preceding fiscal year; or

  .  a lesser number of shares as the board of directors may determine.

                                       46
<PAGE>

   The application of these provisions will result in a total pool of a maximum
of 2,300,000 shares authorized and reserved. The employee stock purchase plan
becomes effective upon the date of this offering. Unless terminated earlier by
the board of directors, the employee stock purchase plan shall terminate in May
2010.

   The employee stock purchase plan, which is intended to qualify under Section
423 of the Internal Revenue Code, will be implemented by a series of
overlapping offering periods of approximately 24 months' duration, with new
offering periods (other than the first offering period) commencing on May 1 and
November 1 of each year. Each offering period will generally consist of four
consecutive purchase periods of six months' duration, at the end of which an
automatic purchase will be made for participants. The initial offering period
is expected to commence on the date of this offering and end on April 30, 2002;
the initial purchase period is expected to begin on the date of this offering
and end on April 30, 2001. The employee stock purchase plan will be
administered by the board of directors or by a committee appointed by the
board. Our employees (including officers and employee directors), and employees
of any majority-owned subsidiary designated by the board, are eligible to
participate in the employee stock purchase plan if they are employed by us or
any such subsidiary for at least 20 hours per week. The employee stock purchase
plan permits eligible employees to purchase common stock through payroll
deductions, which in any event may not exceed 10% of an employee's eligible
compensation per offering period. The purchase price is equal to 85% of the
lower of the fair market value of the common stock at the beginning of each
offering period or at the end of each purchase period. Employees may end their
participation in the employee stock purchase plan at any time during an
offering period, and participation ends automatically on termination of
employment.

   An employee cannot be granted an option under the employee stock purchase
plan if immediately after the grant the employee would own stock and/or hold
outstanding options to purchase stock equaling 5% or more of the total voting
power or value of all classes of our stock or stock of our subsidiaries, or if
the option would permit an employee's rights to purchase stock under the
employee stock purchase plan at a rate that exceeds $25,000 of fair market
value of such stock for each calendar year in which the option is outstanding.
In addition, no employee may purchase more than 2,000 shares of common stock
under the employee stock purchase plan in any one purchase period. If the fair
market value of the common stock on a purchase date of an offering period
(other than the final purchase date) is less than the fair market value at the
beginning of the offering period, each participant in that offering period
shall automatically be withdrawn from the offering period after purchasing
shares on the purchase date and be re-enrolled in a new 24 month offering
period beginning on the first business day following the purchase date.

   If we merge or consolidate with or into another corporation or sell all or
substantially all of our assets to another corporation, each right to purchase
stock under the employee stock purchase plan will be assumed or an equivalent
right substituted by the successor corporation. However, the board of directors
will shorten any ongoing offering period so that employees' rights to purchase
stock under the employee stock purchase plan are exercised prior to the
transaction in the event that the successor corporation refuses to assume each
purchase right or to substitute an equivalent right. The board of directors has
the power to amend or terminate the employee stock purchase plan and to change
or terminate offering periods as long as such action does not adversely affect
any outstanding rights to purchase stock thereunder. However, the board of
directors may amend or terminate the employee stock purchase plan or an
offering period even if it would adversely affect outstanding options in order
to avoid incurring adverse accounting charges.

 401(k) Plan

   We have established a tax-qualified employee savings and retirement plan
(the "401(k) Plan") for all of our employees who satisfy eligibility
requirements, including requirements relating to age and length of service.
Pursuant to the 401(k) Plan, employees may elect to reduce their current
compensation by up to the lower of 18% or the statutorily prescribed limit and
have the amount of such reduction contributed to the 401(k) Plan. The 401(k)
Plan permits us to make additional discretionary matching contributions. The
401(k) Plan is intended to qualify under Section 401 of the Internal Revenue
Code so that contributions by employees or by us to the 401(k) Plan, and income
earned on plan contributions, are not taxable to employees until withdrawn from
the 401(k) Plan, and so that our contributions, if any, will be deductible by
us when made. Currently, we match 25% of the employee's contribution up to 5%
of current compensation.

Medical Advisory Board

   We have assembled a medical advisory board consisting of practicing
interventional cardiologists to assist in the review of the Duett sealing
device, formulation of appropriate clinical studies and future product
developments. In addition to our Medical Director, Dr. Gary Gershony, our
medical advisory board is comprised of:

   Dr. Donald Baim, who is Professor of Medicine at Harvard Medical School and
Director, Center for Minimally Invasive Therapy, at Brigham and Women's
Hospital in Boston, Massachusetts.

   Dr. Stephen Ellis, who is the Director of the Sones Cardiac Catheterization
Laboratory at The Cleveland Clinic Foundation in Cleveland, Ohio.

   Dr. Martin Leon, who is the Chief Executive Officer of the Cardiology
Research Foundation at Lenox Hill Hospital in New York, New York.

   Dr. Michael Mooney, who is the Director of Interventional Cardiology at the
Minneapolis Heart Institute in Minneapolis, Minnesota.

   Prof. Dr. Sigmund Silber, who is an interventional cardiologist at Muller
Hospital in Munich, Germany and performed the first clinical study of the Duett
sealing device.

   Dr. Arne Tofte, who is an interventional radiologist with The National
Hospital of the University of Oslo in Norway.

   Dr. James Wilentz, who is an interventional cardiologist at the Beth Israel
Medical Center in New York, New York.

                              CERTAIN TRANSACTIONS

   In December 1998, we issued 1,777,777 shares of Series B preferred stock at
$4.50 per share. Of this amount, Stephens Vascular Preferred, LLC, an affiliate
of Stephens Inc., purchased 1,221,466 shares. Mr. James Jacoby Jr., one of our
directors, is a Managing Director of Stephens Inc. Affiliates of Olympic
Venture Partners, a 5% beneficial shareholder, purchased a total of 100,000
shares of Series B preferred stock. Mr. Langeler, one of our directors, is a
general partner of Olympic Venture Partners and possesses voting control of the
entities noted above. TGI Fund II, LC, an affiliate of Tredegar Investments and
a 5% beneficial shareholder, purchased a total of 100,000 shares of Series B
preferred stock.

   In connection with the Series B preferred stock purchase agreement, we
entered into a put and option agreement with Stephens Vascular Preferred, LLC.
Under this agreement, we have the right to sell to Stephens Vascular Preferred,
LLC, and Stephens Vascular Options, LLC has the right to purchase from us, up
to 600,000 shares of our common stock at $5.00 per share. On June 30, 1999 we
exercised our right under this agreement and issued 600,000 shares of common
stock to Stephens Vascular Preferred, LLC in exchange for $3,000,000. On
December 28, 1999, Stephens Vascular Options, LLC exercised its right under
this agreement and purchased 600,000 shares of common stock in exchange for
$3,000,000.

   Also in connection with the Series B preferred stock purchase agreement, we
granted Stephens Vascular Options, LLC the option to purchase from us up to
285,714 shares of our common stock at $7.00 per share. On December 28, 1999,
Stephens Vascular Options, LLC exercised its right under this agreement and
purchased 285,714 shares of common stock in exchange for $2,000,000.

   All shares of our preferred stock will convert into shares of common stock
upon the closing of our initial public offering. Some of these shares were sold
or issued to 5% shareholders and entities affiliated with directors. We sold
these shares pursuant to preferred stock purchase agreements on substantially
similar terms as were sold to nonaffiliated purchasers. We believe that the
shares issued in these transactions were sold at the then fair market value of
the shares and that the terms of these transactions were no less favorable than
we could have obtained from unaffiliated third parties. The following table
summarizes the Series A and Series B preferred stock purchased by 5%
shareholders and entities affiliated with our directors and their affiliates:

                             PRINCIPAL SHAREHOLDERS

   The following table provides information concerning beneficial ownership of
our common stock as of June 1, 2000 for:

  .  each person or group that we know owns more than 5% of our outstanding
     common stock;

  .  each of our named executive officers;

  .  each of our directors; and

  .  all of our directors and executive officers as a group.

   The following table lists the applicable percentage of beneficial ownership
based on 9,055,168 shares of common stock outstanding as of June 1, 2000, as
adjusted to reflect the conversion of the outstanding shares of preferred stock
upon completion of this offering. The table also lists the applicable
percentage of beneficial ownership based on 12,055,168 shares of common stock
outstanding upon completion of this offering, assuming no exercise of the
underwriters' overallotment option.

   Beneficial ownership is determined in accordance with rules of the
Securities and Exchange Commission, and generally includes voting power and/or
investment power with respect to the securities held. The fourth column shows
separately shares of common stock subject to options currently exercisable or
exercisable within 60 days after June 1, 2000 by the directors and named
executive officers individually and all directors and executive officers as a
group. These shares are included in the first column of the table below. Shares
of common stock which may be acquired by exercise of stock options are deemed
outstanding for purposes of computing the percentage beneficially owned by the
persons holding such options but are not deemed outstanding for purposes of
computing the percentage beneficially owned by any other person. Except as
otherwise noted, the persons or entities named have sole voting and investment
power with respect to all shares shown as beneficially owned by them.

                          DESCRIPTION OF CAPITAL STOCK

   Our authorized capital stock consists of 40,000,000 shares of capital stock,
par value $.01 per share. Unless otherwise designated by our board of
directors, all issued shares are deemed common stock with equal rights and
preferences.

Common Stock

   As of June 1, 2000, there were 5,277,391 shares of common stock outstanding,
held by 158 shareholders of record.

   Holders of our common stock do not have cumulative voting rights and are
entitled to one vote for each share held of record on all matters submitted to
a vote of the shareholders, including the election of directors. Holders of our
common stock are entitled to receive ratably such dividends, if any, as may be
declared by the board of directors out of funds legally available therefor,
subject to the prior rights of any preferred stock then outstanding. See
"Dividend Policy."

   Upon a liquidation, dissolution or winding up of Vascular Solutions, the
holders of our common stock will be entitled to share ratably in the net assets
legally available for distribution to shareholders after the payment of all
debts and other liabilities of Vascular Solutions, subject to the prior rights
of any preferred stock then outstanding. Holders of our common stock have no
preemptive or conversion rights or other subscription rights and there are no
redemption or sinking funds provisions applicable to the common stock. All
outstanding shares of common stock are, and the common stock outstanding upon
completion of this offering will be, fully paid and nonassessable.

Preferred Stock

   Upon the closing of this offering, all of our outstanding shares of
preferred stock will convert into 3,777,777 shares of common stock. These
shares of preferred stock will no longer be authorized, issued or outstanding
after completion of this offering.

   Our board of directors has the authority, without further action by the
shareholders, to issue from time to time shares of preferred stock in one or
more series and to fix the number of shares, designations and preferences,
powers and relative, participating, optional or other special rights and the
qualifications or restrictions thereof. The preferences, powers, rights and
restrictions of different series of preferred stock may differ with respect to
dividend rates, amounts payable on liquidation, voting rights, conversion
rights, redemption provisions, sinking fund provisions and purchase funds and
other matters.

   The issuance of preferred stock could decrease the amount of earnings and
assets available for distribution to holders of common stock or adversely
affect the rights and powers, including voting rights, of the holders of common
stock. It may have the effect of delaying, deferring or preventing a change in
control of Vascular Solutions. We currently do not plan to issue any shares of
preferred stock.

Registration Rights

   After this offering, the holders of 3,777,777 shares of common stock will be
entitled to rights with respect to the registration of these shares under the
Securities Act as follows:

   Demand Registration Rights: At any time after six months from the date of
   this prospectus, the holders of at least 51% of these shares of common stock
   can request that we register all or a

                                       52
<PAGE>

   portion of their shares. Upon such a request, we must, subject to
   restrictions and limitations, use our best efforts to cause a registration
   statement covering the number of shares of common stock that are subject to
   the request to become effective. The holders may only require us to file
   two registration statements in response to their demand registration
   rights.

   Piggyback Registration Rights: The holders of these shares can request that
   we register their shares anytime we are filing a registration statement to
   register securities for our own account. These registration opportunities
   are unlimited but the number of shares that can be registered may be cut
   back in limited situations by the underwriters.

   Form S-3 Registration Rights: The holders of over 20% of these shares can
   request that we register their shares if we are eligible to file a
   registration statement on Form S-3. The holders may only require us to file
   one registration statement on Form S-3 per twelve-month period.

   In addition, the holders of warrants to purchase 168,000 shares of common
stock are entitled to rights with respect to the registration of the shares
underlying their warrants under the Securities Act. At any time after the
closing of our initial public offering, the holders of at least 51% of these
warrants can request that we register the shares of common stock underlying
these warrants. In addition, the holders of these warrants can request that we
register the shares underlying these warrants anytime we are filing a
registration statement to register securities for our own account. The
registration rights of the warrant holders are subject to restrictions and
limitations.

   All of these registration rights terminate when the shares may be sold
under Rule 144(k) under the Securities Act.

Warrants and Stock Options

   We currently have outstanding warrants to purchase 268,000 shares of common
stock. Of this amount, warrants to purchase 100,000 shares of common stock
have an exercise price of $1.50 per share and expire in January and February
2007, warrants to purchase 68,000 shares of common stock have an exercise
price of $3.00 per share and expire in December 2007, and warrants to purchase
100,000 shares of common stock have an exercise price of $5.00 per share and
expire in June 2004.

Provisions of our Articles and State Law Provisions with Potential
Antitakeover Effects

   The existence of authorized but unissued preferred stock, described above,
and certain provisions of Minnesota law, described below, could have an anti-
takeover effect. These provisions are intended to provide management with
flexibility, to enhance the likelihood of continuity and stability in the
composition of our board of directors and the policies of our board and to
discourage an unsolicited takeover of Vascular Solutions, if our board of
directors determines that such a takeover is not in the best interests of
Vascular Solutions and our shareholders. However, these provisions could have
the effect of discouraging attempts to acquire Vascular Solutions, which could
deprive our shareholders of opportunities to sell their shares of common stock
at prices higher than prevailing market prices.

   Section 302A.671 of the Minnesota Business Corporation Act applies, with
exceptions, to any acquisition of our voting stock from a person other than
us, and other than in connection with certain mergers and exchanges to which
we are a party, that results in the beneficial ownership of 20% or more of the
voting stock then outstanding. Section 302A.671 requires approval of any such
acquisitions by a majority vote of our shareholders before its consummation.
In general, shares acquired in the absence of such approval are denied voting
rights and are redeemable at their then

                                      53
<PAGE>

fair market value by us within 30 days after the acquiring person has failed
to give a timely information statement to us or the date the shareholders
voted not to grant voting rights to the acquiring person's shares.

   Section 302A.673 of the Minnesota Business Corporation Act generally
prohibits any business combination by us, or by any of our subsidiaries, with
any shareholder that purchases ten percent or more of our voting shares within
four years following that interested shareholder's share acquisition date. The
business combination may be permitted if it is approved by a committee of all
of the disinterested members of our board of directors before the interested
shareholder's share acquisition date.

Listing

   We have applied for quotation of our common stock on the Nasdaq National
Market under the symbol "VASC."

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is Wells Fargo Bank
Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Upon the closing of this offering, we will have 12,055,168 shares of common
stock outstanding, assuming (1) the conversion of all outstanding shares of our
preferred stock into shares of common stock, (2) no exercise of the
underwriters' over-allotment option and (3) no exercise of outstanding options
or warrants to purchase common stock after June 1, 2000. Of these shares, the
3,000,000 shares of common stock being sold in this offering will be freely
tradeable without restriction or further registration under the Securities Act,
except for shares held by our "affiliates," as such term is defined in Rule 144
under the Securities Act. These shares may generally only be sold in compliance
with the limitations of Rule 144 described below.

   The remaining 9,055,168 shares were issued and sold by us in private
transactions, are restricted securities and may be sold in the public market
only if registered under the Securities Act or if exempt from registration
under Rules 144, 144(k) or 701 under the Securities Act, which rules are
summarized below. Subject to the agreements between our shareholders and the
underwriters, described below, and the provisions of Rules 144, 144(k) and 701,
additional shares will be available for sale in the public market, subject in
the case of shares held by affiliates to compliance with volume restrictions,
as follows:

  .  302,250 shares will be available for immediate sale in the public market
     on the date of this prospectus;

  .  87,800 shares will be available for sale beginning 90 days after the
     date of this prospectus; and

  .  8,665,118 shares will be available for sale upon the expiration of
     agreements between our shareholders and the underwriters at varying
     dates beginning 180 days after the date of this prospectus.

   In general, under Rule 144, beginning 90 days after the date of this
prospectus, a person or persons whose shares are aggregated, including an
affiliate, who has beneficially owned restricted shares for at least one year,
is entitled to sell these shares. However, the number of these shares sold
within any three-month period may not exceed the greater of 1% of the then
outstanding shares of common stock, approximately 120,000 shares immediately
after this offering, or the average weekly trading volume of our common stock
on the Nasdaq National Market during the four calendar weeks preceding the date
of such sale. Sales under Rule 144 also are subject to requirements pertaining
to the manner and notice of such sales and the availability of current public
information concerning Vascular Solutions.

   Under Rule 144(k), a person who is not deemed to have been an affiliate of
Vascular Solutions at any time during the 90 days before a sale and who has
beneficially owned the shares proposed to be sold for at least two years would
be entitled to sell these shares without regard to the requirements described
above. To the extent that shares were acquired from an affiliate of Vascular
Solutions, the transferee's holding period for the purpose of effecting a sale
under Rule 144(k) commences on the date of transfer from the affiliate.

   Rule 701 provides that, beginning 90 days after the date of this prospectus,
persons other than affiliates may sell shares of common stock acquired from us
in connection with written compensatory benefit plans, such as our stock option
and stock award plan, subject only to the manner of sale provisions of Rule
144. Beginning 90 days after the date of this prospectus, affiliates may sell
these shares of common stock subject to all provisions of Rule 144 except the
one-year minimum holding period.

   Approximately six months after the date of this prospectus, we intend to
file a registration statement on Form S-8 under the Securities Act to register
all shares of common stock issuable under our stock option and stock award
plan. See "Management--Benefit Plans." This Form S-8 registration statement is
expected to become effective immediately upon filing and shares covered by that
registration statement will then be eligible for sale in the public markets,
subject to the Rule 144 limitations applicable to affiliates.

   Prior to this offering there has been no public market for our common stock,
and no predictions can be made regarding the effect, if any, that sales of
shares in the open market or the availability of shares for sale will have on
the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of our common stock in the public market could adversely
affect the prevailing market price.

   All of our directors and executive officers and substantially all of our
shareholders have agreed that they will not, without the prior written consent
of Salomon Smith Barney Inc. sell or otherwise dispose of any shares of common
stock or options to acquire shares of common stock during the 180-day period
following the closing of this offering. See "Underwriting."

   After the closing of this offering, the holders of 3,777,777 shares of our
common stock will be entitled to rights with respect to the registration of
such shares under the Securities Act. See "Description of Capital Stock--
Registration Rights." Registration of these shares under the Securities Act
would result in these shares becoming freely tradeable without restriction
under the Securities Act, except for shares purchased by affiliates,
immediately upon the effectiveness of registration.

   The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of certain legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the shares (other than those
covered by the over-allotment option described below), if they purchase any of
the shares.

   The underwriters, for whom Salomon Smith Barney Inc., Stephens Inc. and
William Blair & Company, L.L.C. are acting as representatives, propose to offer
some of the shares directly to the public at the public offering price set
forth on the cover page of this prospectus and some of the shares to certain
dealers at the public offering price less a concession not in excess of $
per share. The underwriters may allow, and such dealers may reallow, a
concession not in excess of $    per share on sales to certain other dealers.
If all of the shares are not sold at the initial offering price, the
representatives may change the public offering price and the other selling
terms. The representatives have advised us that the underwriters do not intend
to confirm any sales to any accounts over which they exercise discretionary
authority.

   We have granted the underwriters an option, exercisable for 30 days from the
date of this prospectus, to purchase up to 450,000 additional shares of common
stock at the public offering price less the underwriting discount. The
underwriters may exercise such option solely for the purpose of covering over-
allotments, if any, in connection with this offering. To the extent such option
is exercised, each underwriter will be obligated, subject to certain
conditions, to purchase a number of additional shares approximately
proportionate to such underwriter's initial purchase commitment.

   At our request, the underwriters have reserved up to five percent of the
common stock offered by this prospectus for sale to our employees and their
friends and family members and to our business associates at the initial public
offering price set forth on the cover page of this prospectus. This directed
share program will be administered by Salomon Smith Barney Inc. These persons
must commit to purchase no later than the close of business on the day
following the date of this prospectus. The number of shares available for sale
to the general public will be reduced to the extent these persons purchase the
reserved shares.

   We, our officers, directors and our existing shareholders, who own an
aggregate of 8,665,118 shares of our common stock prior to this offering, have
agreed that, for a period of 180 days from the date of this prospectus, we and
they will not, without the prior written consent of Salomon Smith Barney Inc.,
dispose of or hedge any shares of common stock or any securities convertible
into or exchangeable for shares of our common stock, except that we may issue
shares upon the exercise of options granted prior to the date of this
prospectus, and may grant additional options under our share option plan.
Salomon Smith Barney Inc. in its sole discretion may release any of the
securities subject to these lock-up agreements at any time without notice.

   Prior to this offering, there has been no public market for the common
stock. Consequently, the initial public offering price for the shares was
determined by negotiations between us and the representatives. Among the
factors considered in determining the initial public offering price were our
record of operations, our current financial condition, our future prospects,
our markets, the economic conditions in and future prospects for the industry
in which we compete, our management and currently prevailing general conditions
in the equity securities markets, including current market valuations of
publicly traded companies considered comparable to us. There can be no
assurance, however, that the prices at which the shares will sell in the public
market after this offering will not be lower than the price at which they are
sold by the underwriters or that an active trading market in the common stock
will develop and continue after this offering.

   We have applied to have the common stock included for quotation on the
Nasdaq National Market under the symbol "VASC."

   The following table shows the underwriting discounts and commissions to be
paid to the underwriters by us in connection with this offering. These amounts
are shown assuming both no exercise and full exercise of the underwriters'
option to purchase additional shares of common stock.

</TABLE>

   In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell shares of common stock in the open market.
These transactions may include short sales, syndicate covering transactions and
stabilizing transactions. Short sales involve syndicate sales of common stock
in excess of the number of shares to be purchased by the underwriters in the
offering, which creates a syndicate short position. "Covered" short sales are
sales of shares made in an amount up to the number of shares represented by the
underwriters' over-allotment option. Transactions to close out the covered
syndicate short position involve either purchases of the common stock in the
open market after the distribution has been completed or the exercise of the
over-allotment option. In determining the source of shares to close out the
covered syndicate short position, the underwriters will consider, among other
things, the price of shares available for purchase in the open market as
compared to the price at which they may purchase shares through the over-
allotment option. The underwriters may also make "naked" short sales of shares
in excess of the over-allotment option. The underwriters must close out any
naked short position by purchasing shares of common stock in the open market. A
naked short position is more likely to be created if the underwriters are
concerned that there may be downward pressure on the price of the shares in the
open market after pricing that could adversely affect investors who purchase in
the offering. Stabilizing transactions consist of bids for or purchases of
shares in the open market while the offering is in progress.

   The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

   Any of these activities may have the effect of preventing or retarding a
decline in the market price of the common stock. They may also cause the price
of the common stock to be higher than the

                                       58
<PAGE>

price that would otherwise exist in the open market in the absence of these
transactions. The underwriters may conduct these transactions on the Nasdaq
National Market or in the over-the-counter market, or otherwise. If the
underwriters commence any of these transactions, they may discontinue them at
any time.

   In addition, in connection with this offering, certain of the underwriters
(and selling group members) may engage in passive market making transactions in
the common stock on the Nasdaq National Market, prior to the completion of the
offering. Passive market making consists of displaying bids on the Nasdaq
National Market no higher than the bid prices of independent market makers and
making purchases at prices no higher than those independent bids and effected
in response to order flow. Net purchases by a passive market maker on each day
are limited to a specified percentage of the passive market maker's average
daily trading volume in the common stock during a specified period and must be
discontinued when such limit is reached. Passive market making may cause the
price of the common stock to be higher than the price that otherwise would
exist in the open market in the absence of such transactions. If passive market
making is commenced, it may be discontinued at any time.

   A prospectus in electronic format may be made available on the websites
maintained by one or more of the underwriters. The underwriters may agree to
allocate a number of shares to underwriters for sale to their online brokerage
account holders. The representatives will allocate shares to underwriters that
may make Internet distributions on the same basis as other allocations.

   We estimate that our total expenses for this offering will be $350,000.

   We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

   The rules of the National Association of Securities Dealers, Inc. (the
"NASD") provide that an NASD member may not participate in a public offering of
an issuer's securities if more than 10% of the issuer's common stock is
beneficially owned by the member participating in the distribution of the
offering, unless a "qualified independent underwriter" has been engaged as
required by the rules of the NASD. Stephens Inc. beneficially owns more than
10% of our common stock and is participating in the distribution of this
offering.

   In view of this ownership, this offering is being conducted in accordance
with rule 2720(d)(2) of the NASD conduct rules, and Salomon Smith Barney Inc.
is acting as "qualified independent underwriter" within the meaning of these
rules. In connection with this offering, Salomon Smith Barney Inc. has
participated in the preparation of the registration statement of which this
prospectus forms a part. It has exercised its usual standards of "due
diligence" during its participation and has recommended the maximum price at
which the common stock may be offered.

                                 LEGAL MATTERS

   Dorsey & Whitney LLP, Minneapolis, Minnesota, will pass upon the validity of
the issuance of shares of common stock offered by this prospectus for Vascular
Solutions. Certain legal matters will be passed on for the underwriters by
Katten Muchin Zavis, Chicago, Illinois.

                         Report of Independent Auditors

Board of Directors and Shareholders
Vascular Solutions, Inc.

   We have audited the balance sheets of Vascular Solutions, Inc. as of
December 31, 1998 and 1999, and the related statements of operations, changes
in shareholders' equity and cash flows for each of the three years in the
period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Vascular Solutions, Inc. at
December 31, 1998 and 1999, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999, in
conformity with accounting principles generally accepted in the United States.

Impairment of Long-Lived Assets

   The Company will record impairment losses on long-lived assets used in
operations when indicators of impairment are present and the undiscounted cash
flows estimated to be generated by those assets are less than the assets'
carrying amount. The amount of impairment loss recorded will be measured as the
amount by which the carrying value of the assets exceeds the fair value of the
assets.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

Pro Forma Shareholders' Equity

   Upon the closing of the Company's planned initial public offering, all
outstanding shares of Series A and B preferred stock will automatically convert
into 3,777,777 shares of common stock. The pro forma effects of these
transactions are unaudited and have been reflected in the accompanying pro
forma balance sheet at March 31, 2000.

Revenue Recognition

   The Company generally sells its products to international distributors which
subsequently resell the products to hospitals and clinics. The Company has
agreements with each of its distributors which provide that title and risk of
loss pass to the distributor upon shipment of the products to the distributor.
The Company warrants that its products are free from manufacturing defects at
the time of shipment to the distributor. Revenue is recognized upon shipment of
products to distributors following the receipt and acceptance of a
distributor's purchase order. Allowances are provided for estimated warranty
costs at the time of shipment. To date, warranty costs have been insignificant.

Research and Development Costs

   All research and development costs are charged to operations as incurred.

Stock-Based Compensation

   The Company follows Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees ("APB 25"), and related interpretations in
accounting for its stock options. Under APB 25, when the exercise price of
stock options equals the market price of the underlying stock on the date of
grant, no compensation expense is recognized.

   The Company determines the fair value of stock options granted to non-
employees for services using the Black-Scholes valuation method. The fair value
of the stock options granted is expensed over the time period the services are
rendered.

Income Taxes

   Income taxes are accounted for under the liability method. Deferred income
taxes are provided for temporary differences between the financial reporting
and the tax bases of assets and liabilities.

Concentrations of Credit Risk

   Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash and cash equivalents and accounts
receivables. The Company maintains its accounts for cash and cash equivalents
principally at one major bank in the United States. The Company has a formal
written investment policy that restricts the placement of investments to
issuers evaluated as creditworthy. The Company has not experienced any losses
on its deposits of its cash and cash equivalents.

   With respect to accounts receivable, the Company performs credit evaluations
of its customers and does not require collateral. Four customers accounted for
100% of total accounts receivable as of

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

December 31, 1998. Two customers accounted for 51% of total accounts receivable
as of December 31, 1999. Three customers accounted for 69% of total accounts
receivable as of March 31, 2000 (unaudited).

Net Loss Per Share

   Under Financial Accounting Standards Board Statement No. 128, Earnings per
Share, basic earnings per share is based on the weighted average shares of
common stock outstanding during the period. Diluted earnings per share includes
any dilutive effects of options, warrants and convertible securities. Diluted
loss per share as presented is the same as basic loss per share as the effect
of outstanding options, warrants and convertible securities is antidilutive.

Pro Forma Net Loss Per Share

   Pro forma net loss per share for the year ended December 31, 1999 and the
three months ended March 31, 2000 is computed using the weighted average number
of common shares outstanding, including the pro forma effects of the automatic
conversion of the Company's Series A and B preferred stock into shares of the
Company's common stock as if such conversion occurred on January 1, 1999, or at
the date of original issuance, if later. The resulting pro forma adjustment
includes an increase in the weighted average shares used to compute basic and
diluted net loss per share of approximately 3,777,777 shares for the year ended
December 31, 1999 and for the three months ended March 31, 2000. The pro forma
effects of these transactions are unaudited.

Interim Financial Statements

   The interim financial statements for the three months ended March 31, 1999
and 2000, are unaudited and have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles. In the opinion of the Company's management, the
unaudited interim financial statements contain all adjustments, consisting of
normal recurring adjustments, considered necessary for a fair presentation. The
results of operations for the interim periods are not necessarily indicative of
the results of the entire year.

Reclassifications

   Certain prior years' balances were reclassified to conform to the current
year presentation.

4. Leases

   The Company leases a 24,000 square foot office and manufacturing facility
under an operating lease agreement, which expires in March 2003. The Company
may terminate the lease agreement at any time after March 2001 with a six-month

upon liquidation. The holders of Series B preferred stock are also entitled to
receive dividends prior and in preference to the Series A preferred stock and
the common stock at the rate of $.36 per share per annum when, as and if
declared by the Board of Directors. Such dividends shall be cumulative.

   In connection with the Series B preferred stock Purchase Agreement, the
Company entered into a Put and Option Agreement (the "Agreement") with one of
the Series B investors (the "Investor"). The Agreement provided the Company
with the right to sell, and the Investor the obligation to purchase, up to
$3,000,000 of common stock at $5.00 or $6.00 per share based on the Company
attaining certain milestones. The Company exercised its right and sold 600,000
shares of common stock to the Investor at $5.00 per share on June 30, 1999. In
addition, the Agreement provided the Investor with the right to buy, and the
Company the obligation to sell, up to $3,000,000 common stock at $5.00 or $6.00
per share based on the Company attaining certain milestones. The Investor
exercised its right and purchased 600,000 shares of common stock from the

a five year supply agreement. The warrant is exercisable at any time and
expires on June 10, 2004. Using the Black-Scholes valuation model, the Company
determined a fair value of $257,000 for the warrant and expensed this amount
during the year ended December 31, 1999. The amount was classified as research
and development expense because it related to product development activities.

   On December 31, 1999, the Company had 168,000 warrants outstanding at a
weighted average exercise price of $2.11 per share.

7. Stock Options

 Stock Option Plan

and nonqualified stock options to employees, directors and consultants. As of
December 31, 1999, the Company reserved 1,400,000 shares of common stock under
the Stock Option Plan. Under the Stock Option Plan, incentive stock options
must be granted at an exercise price not less than the fair market value of the
Company's common stock on the grant date. The exercise price of a non-qualified
option granted under the Stock Option Plan must not be less than 50% of the
fair market value of the Company's common stock on the grant date. The Board of
Directors determined the fair value of the common shares underlying options by
assessing the business progress of the Company as well as the market conditions
for medical device companies and other external factors. The options expire on
the date determined by the Board of Directors but may not extend more than ten
years from the grant date. The Stock Option Plan also permits the granting of
stock appreciation rights; restricted stock and

other stock based awards. The incentive stock options generally become
exercisable over a four-year period and the non-qualified stock options

   For purposes of calculating the above required disclosure, the fair value of
each option grant is estimated on the date of grant using the Black-Scholes
option pricing model. The fair value of the Company's stock options was
estimated assuming no expected dividends and the following weighted average
assumptions:

</TABLE>

   The weighted average fair value of options granted with an exercise price
equal to the deemed stock price on the date of grant during 1997, 1998 and 1999
was $1.21, $1.97 and $3.82 per share.

   For the years ended December 31, 1997, 1998 and 1999, the Company recorded
compensation expense of $25,440, $78,400 and $22,660 in connection with non-
qualified stock options granted to board of directors' members, medical
advisory board members and outside consultants.

 Deferred Compensation

   During 1999, the Company recorded $140,625 of deferred compensation for
certain stock options granted for the excess of the deemed value for accounting
purposes of common stock issuable upon exercise of such options over the
aggregate exercise price of such options. The weighted average fair value of
these options was $2.74. Deferred compensation recorded is amortized ratably
over the period that the options vest and is adjusted for options which have
been canceled. Deferred compensation expense was $49,694 for the year ended
December 31, 1999.

8. Employee Retirement Savings Plan

   In February 1998, the Company implemented an employee retirement savings
plan (the "401(k) Plan") which qualifies under Section 401(k) of the Internal
Revenue Code. The 401(k) Plan provides eligible employees with an opportunity
to make tax-deferred contributions into a long-term investment and savings
program. All employees over the age of 21 are eligible to participate in the
401(k) Plan beginning with the first quarterly open enrollment date following
start of employment. The 401(k) Plan allows eligible employees to contribute up
to 18% of their annual compensation with the Company contributing an amount
equal to 25% of the first 5% contributed to the 401(k)

Plan. No employer contributions were made for the year ended December 31, 1998.
The Company recorded an expense of $21,573 for contributions to the 401(k) Plan
for the year ended December 31, 1999.

9. Concentrations of Credit and Other Risks

   The Company operates in a single industry segment and sells its product to
distributors who, in turn, sell to medical clinics. The Company sells its
product in foreign countries through independent distributors denominated in
United States dollars. Loss, termination or ineffectiveness of distributors to
effectively promote the Company's product could have a material adverse effect
on the Company's financial condition and results of operations.

   Sales to significant customers as a percentage of total revenues are as
follows for the years ended December 31, 1998 and 1999:

   The Company performs ongoing credit evaluations of its customers but does
not require collateral. There have been no material losses on customer
receivables.

10. Dependence on Key Suppliers

   The Company purchases certain key components from single source suppliers.
Any significant component delay or interruption could require the Company to
qualify new sources of supply, if available, and could have a material adverse
effect on the Company's financial condition and results of operations.

11. Commitments and Contingencies

   In July 1999, the Company was named as a defendant in a patent infringement
lawsuit brought by a competitor. The complaint requested a judgment that the
Company's device infringes and, following FDA approval will infringe, a United
States patent held by the competitor and asks for relief in the form of an
injunction that would prevent the Company from selling its product in the
United States as well as an award of attorney's fees, costs and disbursements.
On August 12, 1999, the Company filed its answer to this lawsuit and brought a
counterclaim alleging unfair competition and tortious interference against
Datascope. On August 20, 1999, the Company moved for summary judgment to
dismiss Datascope's claims. On March 15, 2000, the court granted summary
judgment dismissing all of Datascope's claims, subject to the right of
Datascope to recommence the litigation after our receipt of FDA approval of our
Duett sealing device. On July 12, 2000, after the Company received FDA
approval, Datascope recommenced this litigation, alleging that the Duett
sealing device infringes a United States patent held by Datascope and
requesting relief in the form of an injunction that would prevent the Company
from selling its product in the United States, damages caused by the

alleged infringement, and other costs, disbursements and attorneys' fees. The
Company believes the allegations included in the complaint are without merit,
and it intends to defend the lawsuit vigorously. It is not possible to predict
the timing or outcome of the Datascope litigation, including whether the
Company will be prohibited from selling the Duett sealing device in the United
States or internationally, or to estimate the amount or range of potential
loss, if any.

   On September 22, 1999, the Company received a letter from the Daig division
of St. Jude Medical, Inc. claiming that the manufacture, use, marketing and
sale of our Duett sealing device infringes upon certain United States patents
licensed by Daig. The letter referenced a prior letter dated August 18, 1998
from the Company to the prior licensee of those patents in which the Company
made a proposal intended to avoid the anticipated litigation over those
patents. The proposed license was rejected. On July 3, 2000, the Company was
named as the defendant in a patent infringement lawsuit brought by St. Jude
Medical and Daig in the United States District Court for the District of
Minnesota. The complaint requests a judgment that the Company's Duett sealing
device infringes a series of four patents held by St. Jude Medical and asks for
relief in the form of an injunction that would prevent the Company from selling
its product in the United States, damages caused by the manufacture and sale of
the Company's product, and other costs, disbursements and attorneys' fees. The
Company believes the allegations included in the complaint are without merit,
and it intends to defend the lawsuit vigorously. It is not possible to predict
the timing or outcome of the St. Jude Medical litigation, including whether the
Company will be prohibited from selling the Duett sealing device in the United
States or internationally, or to estimate the amount or range of potential
loss, if any.

Item 14. Indemnification of Directors and Officers

   Section 302A.521 of the Minnesota Statutes provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan for the same judgments, penalties or
fines; (2) acted in good faith; (3) received no improper personal benefit and
Section 302A.255 (with respect to director conflicts of interest), if
applicable, has been satisfied; (4) in the case of a criminal proceeding, had
no reasonable cause to believe the conduct was unlawful; and (5) in the case of
acts or omissions in such person's official capacity for the corporation,
reasonably believed that the conduct was in the best interests of the
corporation, or in the case of acts or omissions in such person's official
capacity for other affiliated organizations, reasonably believed that the
conduct was not opposed to the best interests of the corporation. Section
302A.521 also requires payment by a corporation, upon written request, of
reasonable expenses in advance of final disposition of the proceeding in
certain instances. A decision as to required indemnification is made by a
disinterested majority of the Board of Directors present at a meeting at which
a disinterested quorum is present, or by a designated committee of the Board,
by special legal counsel, by the shareholders or by a court.

   Provisions regarding indemnification of officers and directors of Vascular
Solutions to the extent permitted by Section 302A.521 are contained in Vascular
Solutions' bylaws.

Item 17. Undertakings

   The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.


                                      II-4

   The undersigned registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.
