                   SUBJECT TO COMPLETION, DATED AUGUST 6, 1997



                                ATS MEDICAL, INC.

                                1,568,940 Shares

                                  Common Stock

     This Prospectus relates to 1,568,940 shares (the "Shares") of common stock,
$.01 par value (the "Common Stock"), of ATS Medical, Inc. ("ATS" or the
"Company") offered for the account of Itochu Corporation (the "Selling
Shareholder"). The Shares may be sold from time to time by the Selling
Shareholder. The Company will not receive any of the proceeds from the sale of
the Shares. The Company has agreed to pay expenses incurred in registering the
Shares, including legal and accounting fees.

     The Shares were acquired by the Selling Shareholder in a private
transaction on February 7, 1997 pursuant to a Stock Purchase Agreement. The
Shares are "restricted securities" under the Securities Act of 1933, as amended
(the "Act"), prior to their sale hereunder. This Prospectus has been prepared
for the purpose of registering the Shares under the Act to allow for future
sales by the Selling Shareholder to the public without restriction. To the
knowledge of the Company, the Selling Shareholder has made no arrangement with
any brokerage firm for the sale of the Shares. The Selling Shareholder may be
deemed to be an "underwriter" within the meaning of the Act. Any commissions
received by a broker or dealer in connection with resales of the Shares may be
deemed to be underwriting commissions or discounts under the Act. See "Plan of
Distribution."

     The Shares have not been registered under the securities laws of any state
or other jurisdiction as of the date of this Prospectus. Brokers or dealers
should confirm the existence of an exemption from registration or effectuate
such registration in connection with any offer and sale of the Shares.

     The Common Stock is traded on the Nasdaq National Market under the symbol
"ATSI." On August 5, 1997, the closing sale price of the Common Stock reported
by Nasdaq was $6.00 per share.


          THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
           SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
                 COMMISSION NOR HAS THE SECURITIES AND EXCHANGE
                  COMMISSION OR ANY STATE SECURITIES COMMISSION
                  PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
                      PROSPECTUS. ANY REPRESENTATION TO THE
                         CONTRARY IS A CRIMINAL OFFENSE.

ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

       Minnesota Statutes Section 302A.521 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; (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) reasonably believed that the conduct was in the best interests
of the corporation in the case of acts or omissions in such person's official
capacity for the corporation or reasonably believed that the conduct was not
opposed to the best interests of the corporation in the case of acts or
omissions in such person's official capacity for other affiliated organizations.
The Bylaws of ATS provide that ATS shall indemnify officers and directors under
such circumstances and to the extent permitted by Section 302A.521 as now
enacted or hereafter amended.

       The Company has established a Self-Insurance Trust Agreement to assist in
funding indemnification of its directors and officers to the extent permissible
under Minnesota Law. The Company has contributed $300,000, plus accrued interest
thereon, to an irrevocable trust (the "Trust") to be invested in government
issued or insured obligations by an independent trustee. The Trust funds may be
used only for indemnification of the Company's officers or directors or, at the
direction of the Company and with the consent of the beneficiaries under the
Trust, to pay directors' and officers' liability insurance premiums. The rights
of the beneficiaries under the Trust are contract rights enforceable against the
Company and the trustee. In addition to the Trust, beginning on November of
1995, the Company has maintained a liability insurance policy for its directors
and officers.

ITEM 17.  UNDERTAKINGS

       The undersigned registrant hereby undertakes:

              (1) To file, during any period in which offers or sales are being
       made, a post-effective amendment to this registration statement:

                     (i) To include any prospectus required by section 10(a)(3)
              of the Securities Act of 1933;

                     (ii) To reflect in the prospectus any facts or events
              arising after the effective date of the registration statement (or
              the most recent post-effective amendment thereof) which,
              individually or in the aggregate, represent a fundamental change
              to such information in the registration statement. Notwithstanding
              the foregoing, any increase or decrease in volume of securities
              offered (if the total dollar value of securities offered would not
              exceed that which was registered) and any deviation from the low
              or high end of the estimated maximum offering range may be
              reflected in the form of prospectus filed with the Commission
              pursuant to Rule 424(b) under the Securities Act if, in the
              aggregate, the changes in volume and price represent no more than
              a 20% change in the maximum aggregate offering price set forth in
              the "Calculation of Registration Fee" table in the effective
              registration statement; and

                     (iii) To include any material information with respect to
              the plan of distribution not previously disclosed in the
              registration statement or any material change in the information
              set forth in the registration statement;

              Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
              apply if the registration statement is on Form S-3 or Form S-8,
              and the information required to be included in a post- effective
              amendment by those paragraphs is contained in periodic reports
              filed by the registrant pursuant to section 13 or section 15(d) of
              the Securities Exchange Act of 1934 that are incorporated by
              reference in the registration statement.

              (2) That, for the purpose of determining any liability under the
       Securities Act of 1933, each such post-effective amendment 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.

              (3) To remove from registration by means of a post-effective
       amendment any of the securities being registered which remain unsold at
       the termination of the offering.

       The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement 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.

       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 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.

                  Re:  Registration Statement on Form S-3

Ladies and Gentlemen:

                  We have acted as counsel to ATS Medical, Inc., a Minnesota
corporation (the "Company"), in connection with a Registration Statement on Form
S-3 (the "Registration Statement") to be filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, relating to the sale of
up to 1,568,940 shares of common stock of the Company, par value $.01 per share
("Common Stock"), of which all such shares will be sold from time to time by the
Selling Shareholder named in the Registration Statement, on the Nasdaq National
Market or otherwise, directly or through underwriters, brokers or dealers.

                  We have examined such documents and have reviewed such
questions of law as we have considered necessary and appropriate for the
purposes of our opinions set forth below. In rendering our opinions set forth
below, we have assumed the authenticity of all documents submitted to us as
originals, the genuineness of all signatures and the conformity to authentic
originals of all documents submitted to us as copies. We have also assumed the
legal capacity for all purposes relevant hereto of all natural persons and, with
respect to all parties to agreements or instruments relevant hereto other than
the Company, that such parties had the requisite power and authority (corporate
or otherwise) to execute, deliver and perform such agreements or instruments,
that such agreements or instruments have been duly authorized by all requisite
action (corporate or otherwise), executed and delivered by such parties and that
such agreements or instruments are the valid, binding and enforceable
obligations of such parties. As to questions of fact material to our opinions,
we have relied upon certificates of officers of the Company and of public
officials.

                  Based on the foregoing, we are of the opinion that the shares
of Common Stock to be sold by the Selling Shareholder pursuant to the
Registration Statement have been duly authorized by all requisite corporate
action and, are validly issued, fully paid and nonassessable.

                  Our opinions expressed above are limited to the laws of the
State of Minnesota.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement, and to the reference to our firm under the
heading "Legal Matters" in the Prospectus constituting part of the Registration
Statement.

Dated:  August 5, 1997


                                       Very truly yours,

                                       /s/ Dorsey & Whitney LLP
