                                                               EXHIBIT 10.1


PORTIONS OF THIS EXHIBIT HAVE BEEN OMITTED AND SEPARATELY FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
TREATMENT.  THE OMITTED PORTIONS ARE IDENTIFIED BY ASTERIKS WITHIN
BRACKETS ([**]).


                               HEADS OF AGREEMENT
                                       for
       Plastic Surgery and Cosmetic Dermatology Tissue Engineered Products


     This Agreement is entered into effective as of May 10, 1999, by and between
Advanced Tissue Sciences, Inc., a Delaware corporation ("ATS"), and INAMED
Corporation, a Delaware corporation ("IMDC"), with respect to the following
facts:
                                    RECITALS

     A.  ATS owns certain patents, intellectual property and know-how
(collectively, the "Intellectual Property Rights") which can be applied toward
developing the following commercial products in the following fields of use or
"Product Categories":

          (1)  "Burn treatment product," which would be a non-viable human
dermal matrix and fibroblast coated biocompatible scaffold (e.g.,
"TransCyte(TM)") for use in cosmetic surgery for the enhancement of normal skin
in connection with procedures such as chemical peels, laser resurfacing or
other aesthetic treatments.

          (2)  "Reconstructive cartilage product," which would be an allogeneic
collagen-based product for use in plastic and reconstructive surgery to provide
human cartilage for aesthetic, cosmetic or other reasons; the primary
anticipated application being rhinoplasty.

          (3)  "Breast reconstruction product," which would be a collagen- and
living cells-based, human matrix product grown outside the body for use in
reconstructive surgery of the human breast, whether following a mastectomy or
lumpectomy, or to treat deformities.

          (4)   "Human collagen product," which would be a collagen-based, human
matrix injectable product for use in the correction of wrinkles and lip
enhancement.

          (5)  "Urinary incontinence product," which would be a collagen-based,
human matrix bulking product for use in the treatment of urinary incontinence.

Taken together, these products, Product Categories, and fields of use are
referred to as the "Product Portfolio."  The Product Categories listed in (1),
(2) and (3) above shall sometimes be called the "First Phase Product
Categories".  The Product Categories listed in (4) and (5) above shall sometimes
be called the "Second Phase Product Categories".

     B.  IMDC desires (1) to collaborate with ATS in the research and
development which is necessary to develop and to identify and formalize the
specifications for each product which comprises the Product Portfolio, (2) to
obtain the appropriate FDA approvals which are necessary to bring the Product
Portfolio to commercial fruition, and (3) to become the exclusive worldwide
licensee authorized to sell, market and distribute the products listed in the
Product Categories.

                                   1

<PAGE>


     C.  IMDC desires to expand its current business as the leading company in
plastic and reconstructive surgery, primarily breast implants, by acquiring and
developing a broad range of collagen-based products (whether bovine-based or
human-based, such as those included within the Product Portfolio).  Toward
that end, IMDC is seeking to acquire Collagen Aesthetics, Inc. (CGEN)
through a friendly, negotiated transaction.

     D.  The parties intend this Agreement to be binding and enforceable on the
parties in accordance with the terms of this Agreement.  The parties understand
and intend that there will be some follow-on implementing agreements to be
drafted, mutually approved and signed by the parties, as further set forth in
this Agreement, for the purpose of implementing the terms of this Agreement.  If
any disputes arise with respect to finalizing the terms of said implementing
agreements, the parties hereby agree that the disputes shall be resolved by
binding arbitration pursuant to Section 7(d) of this Agreement, so that the
implementing agreements can be finalized and signed.  All payments made pursuant
to this Agreement shall be nonrefundable, and this Agreement shall not be
subject to rescission in the event of any dispute with respect to any of the
implementing agreements.

     WHEREFORE, the parties hereto mutually agree to the following principle
terms and agreements:

     1.  GRANT OF LICENSE RIGHT.  ATS hereby grants to IMDC a non-transferable,
exclusive, worldwide license, without sublicense rights, under the Intellectual
Property Rights necessary to make, use and sell products in the First Phase
Product Categories.  A customary form of license agreement containing the
substantive terms from this Agreement and other customary and reasonable terms
shall be drafted, mutually approved and signed by both parties promptly after
the date hereof.

     2.  OPTION TO ACQUIRE LICENSE RIGHTS.  Subject to IMDC completing the
acquisition of at least 50% of CGEN by September 30, 1999, IMDC agrees to
acquire from ATS and ATS agrees to grant IMDC a non-transferable, exclusive,
worldwide license under the Intellectual Property Rights necessary to make, use
and sell products in the Second Phase Product Categories.  This license does not
include any right to sub-license except for the Product Category listed in
clause (5) of Recital A.  Accordingly, until September 30, 1999, with respect to
every aspect of the Second Phase Product Categories, ATS and IMDC will deal
exclusively only with each other; provided, however, that in the event CGEN
is acquired by a third party prior to that date, ATS may give a written notice
that ATS no longer wishes to be bound by this Section 2; and in the event ATS
does give said written notice, then IMDC shall still be entitled to acquire the
exclusive license for the Second Phase Product Categories if IMDC makes payment
to ATS within 30 days after IMDC's receipt of said written notice in the amounts
as specified in Section 3(d) below, notwithstanding the fact that IMDC did not
acquire CGEN.  Upon IMDC so paying for this additional license right, the
license agreement shall be amended to include the Second Phase Product
Categories.

                                    2

<PAGE>


         d.   $4 million cash if IMDC acquires at least 50% of CGEN by
September 30, 1999, payable within ten days after acquisition, or $4 million
cash if IMDC makes the election and pays said $4 million within the 30-day
period specified in Section 2.  $2 million of said payment shall be a license
fee; and the remaining $2 million shall be a capital investment by IMDC, with
IMDC receiving (i) a number of shares of ATS common stock such that the shares
are valued at the greater of (aa) the average closing price per share of ATS

The exercise price of the warrant will be two times the per share price paid
for the shares as calculated according to the formula in this Section 3(d)(i).
The warrant will have a five-year term from the date of $4 million payment.

         e.   A milestone payment of $2 million, payable within 30 days after
the FDA approves a PMA, for each PMA received for each product within the
Product Portfolio, but in no event will these milestone payments exceed an
aggregate of $10 million during the term of this Agreement.

         f.   [**]% basic royalty payment on the net sales of any of the commer-
cialized products comprising the Product Portfolio.

         g.   For each calendar year, an additional royalty payment shall be
paid based on the aggregate net sales of all of the commercialized products
comprising the Product Portfolio, as follows:

              $25 million to $50 million               [**]%
              $50 million to $100 million              [**]%
              $100 million to $150 million             [**]%
              $150 million to $200 million             [**]%
              Above $200 million                       [**]%

         h.   For each calendar year in which the aggregate net sales of all
of the products manufactured by ATS (or its affiliate) and comprising the
Product Portfolio exceed $[**] million, an additional royalty payment equal to
[**]% of the amount by which IMDC's gross profit margin (to be defined in
accordance with GAAP) on such aggregate products is more than [**]%.

                                    4


<PAGE>


         i.   Commencing with the calendar year in which the FDA approves the
first PMA for the first product within a particular Product Category, a minimum
basic royalty payment shall be paid annually for that particular Product
Category according to the following schedule, against which IMDC shall receive
a credit toward any amounts paid under Section 3(f) above for that particular
Product Category for such calendar year:

              Year one          $[**] million*
              Year two          $[**] million
              Year three        $[**] million
              Year four         $[**] million
              After year four   $[**] million
____________________
*   If FDA approval of the first PMA in a Product Category occurs prior to July
1, the minimum royalty payment due shall be $[**] million.

In the event IMDC makes payments under Section 3(g) or 3(h) above, the
obligation to make minimum royalty payments under this Section 3(i) will be
canceled for both that calendar year and the subsequent calendar year.  This
schedule applies to each and every particular Product Category listed in Recital
A.

         j.   IMDC shall sell all products at a commercially reasonable sales
price; and if IMDC elects to sell any of the products at less than a commer-
cially reasonable sales price (e.g., as a "loss leader"), then the royalties
shall be paid on the commercially reasonable sales price, rather than on the
lower actual reduced price.

         k.   All shares issued and shares to be issued on the exercise of
warrants shall (i) be sold and issued pursuant to a customary stock purchase
agreement, (ii) not be resold until after October 1, 2002, at which time the
shares shall be subject to resale restrictions and rights pursuant to Rule 144
promulgated by the Securities and Exchange Commission, and (iii) after
October 1, 2002, have customary stock registration rights for "piggyback"
rights and one "demand" right.  All stock warrants shall be evidenced by a
customary form of stock warrant agreement.

         l.   In the event that any of the payments in clauses (a), (b) and
(c) of this Section 3 are not paid, then all prior payments made by IMDC to
ATS shall remain with ATS, and all rights to the Product Portfolio shall
automatically revert to ATS, and this Agreement shall terminate with the
effects listed in Section 6(d).  In the event that the payment in part (d) of
this Section 3 is not received according to this Agreement, then all rights
related to the Phase Two Products Categories shall be retained by ATS and the
remainder of the rights and obligations of the parties under this Agreement
shall continue in full force and effect.

                                    5

     4.  RESEARCH, DEVELOPMENT AND REGULATORY EFFORTS.

         a.   ATS will be responsible for conducting activities related to
designing the products and manufacturing processes for the Product Portfolio.
A research, development, and regulatory plan (the "R&D Plan") will be jointly
developed on the commencement of activities related to each product.  A
reasonable limit on ATS's expenditures per year for its work under the R&D Plan
is to be determined by the parties hereto, on a product by product basis,
which limit, during the first 18 months of the R&D plan, shall not exceed 50%
of the amount of payments made by IMDC to ATS described in Section 3 (excluding
any capital investment payments) during such 18 month period.  Thereafter,
the parties will in good faith negotiate the future allocation of expenses and
limitations on ATS expenditures, if any, under the R&D Plan.  ATS shall design
such products (including, without limitations, the package size for the
products, the projected shelf life of the products, and the methods for use of
the products) based on specifications that reflect the needs of the marketplace
and reflect the collaborative spirit between IMDC and ATS.

         b.   IMDC will be responsible for planning, conducting and funding all
of the clinical trials and regulatory submissions necessary to obtain commercial
clearance to sell the products comprising the Product Portfolio.  The parties
will fully cooperate in all such research, development and regulatory efforts,
including sharing all data.  However, IMDC will own the clinical study data and
regulatory approvals; provided, that ATS shall have access to such information
for purposes of marketing the Intellectual Property Rights to other parties for
use in products other than those comprising the Product Portfolio.  In the event
of any termination of this Agreement for reasons other than a breach by ATS,
rights to regulatory filings, data and approvals for the Product Portfolio
will automatically be granted to and vested in ATS, and IMDC shall execute and
deliver any and all appropriate documents to evidence and implement said rights.

         c.   ATS and IMDC shall each use commercially reasonable and diligent
efforts to perform its respective activities and responsibilities under the
R&D Plan, in order to develop products and obtain regulatory approvals for
products on a reasonably prompt and diligent basis.

         d.   If the parties are not able to promptly reach mutual agreement
for the R&D Plan for a particular product, then either (i) the unresolved
aspects for said R&D Plan shall be resolved by a decision made jointly by the
Scientific Advisory Boards of ATS and IMDC, (ii) IMDC may make the decision as
to the unresolved aspect for said R&D Plan so long as IMDC shall provide all
of the funding for implementing such unresolved aspect of the R&D Plan for the
particular product, or (iii) the particular product shall be removed from the
license granted to IMDC, and thereafter ATS shall have the sole right to pursue
research development and commercialization efforts to said product.

                                    6

     5.  MANUFACTURING.

         a.   ATS (or an affiliate of ATS) shall have the first right to
manufacture each and every one of the products comprising the Product Portfolio;
and ATS shall sell those products (for which IMDC has obtained and maintained
exclusive license rights pursuant to this Agreement) exclusively to IMDC during
the term of this Agreement, based on forecasts and purchase orders submitted
by IMDC and its affiliated entities or sub-licensees, as outlined below.  ATS
shall elect whether to so manufacture a product by delivering written notice
of election to IMDC at least six months prior to IMDC received PMA approval
for the particular product.

         b.   If ATS elects to manufacture the product, ATS shall charge IMDC a
"transfer price" which reflects commercially reasonable rates. IMDC shall have
customary rights to audit the costs for ATS to manufacture the product.
Recognizing that until ATS achieves a higher utilization rate of its
manufacturing facilities the transfer price may not reflect a realistic price at
which IMDC can sell to its customers, the transfer price plus royalties
payable under Section 3 shall not exceed [**]% of the commercially reasonable
selling price which IMDC charges its customers, except as otherwise noted below.
If said [**]% price would result in a transfer price which is less than [**]
times the direct costs for ATS to manufacture the product, then the parties
shall pursue good faith negotiations for a mutually agreeable transfer price.
If no such agreement is reached, then ATS shall not be obligated to manufacture
and sell product at a transfer price less than [**] times the ATS direct costs
for manufacture; and any such refusal of ATS to manufacture and sell at a
lower price shall not activate the "royalty holiday" referenced in Section 5(d)
below.  Any such inability of IMDC to obtain the product shall excuse IMDC
from its obligation to pay the minimum royalty for the particular Product
Category as specified in Section 3(i) above.

         c.   If ATS (or an affiliate of ATS) exercises its right to manu-
facture, then within 30 days after regulatory approval for the product in the
first market, IMDC will provide a 6-month forecast with estimated monthly
purchase quantities.  IMDC will provide an updated forecast monthly on a
rolling basis.  The first three months of each forecast will be binding on
IMDC and will be treated as a legally binding and firm purchase order.  ATS
agrees to use commercially reasonable and diligent efforts to support any
demand that is higher than the forecast.

         d.   In the event in any calendar month ATS is out of stock with
respect to more than 10% of IMDC's forecasts for a particular product, IMDC
will receive a "royalty holiday", in which case all royalty payments under
Section 3 (including any pro-rata allocation of annual payments) shall be
reduced by [**]% for that month for that particular product.

         e.   The parties will work together from time to time to develop
comprehensive plans for a secondary manufacturing source, and/or adequate
inventory stockpiles, to ensure an adequate level of supply of the commer-
cialized products to suit IMDC's anticipated needs.

                                    7

     6.  TERM OF AGREEMENT; TERMINATION.

         a.   This Agreement shall continue for the later of 15 years or the
expiration of the last of the patents included within the Intellectual
Property Rights (including any improvements, extensions or modifications).

         b.   Subject to the terms of this Section 6, IMDC shall have the
right to extend the term of this Agreement for successive annual renewal terms
by giving to ATS written notice of renewal at least one year in advance.  In
the event of such an extension, the minimum annual royalty payment under
Section 3(i) shall be re-set, on a Product Category-by-Product Category basis,
at 70% of the average annual royalty payment under Section 3(f) for the prior
three years for the particular Product Category.  ATS shall have the right to
reject IMDC's notice of extension for the particular Product Category if the
actual earned royalties paid by IMDC for the particular Product Category have
not exceeded the minimum royalty payment under Section 3(i) for at least three
of the prior five years.

         c.   ATS shall have the right to terminate IMDC's license rights with
respect to any particular Product Category comprising the Product Portfolio if:

              i.    IMDC fails to exceed the minimum annual royalty payments
under Section 3(i) for that particular Product Category for any two years,
commencing after year four as defined in Section 3(i); or

              ii.   Within the time periods agreed upon by the parties from
time to time in the R&D workplan under Section 4,  IMDC does not use
commercially reasonable efforts to obtain PMA approval for (i) 3 of the 5
Product Categories if the option to license the Second Phase Product Categories
under Section 2 is exercised, or (ii) 2 of 3 of the First Phase Product
Categories if the option to licenses the Second Phase Product Categories is
not exercised; provided, however, that in the event ATS retakes the licensing
rights to a Product Category pursuant to Section 4(d), then the thresholds
specified above shall be appropriately reduced in a manner which does not
increase the percentage of Product Categories for which a PMA must be obtained;
or

              iii.  IMDC fails to comply with the R&D Plan mutually agreed at
commencement of such activities for the particular product or Product Category,
and said failure is not cured by IMDC within 30 days after written notice of
the failure is delivered to IMDC; or

              iv.   IMDC is in material breach of any of its other obligations
with respect to the particular Product Category, and said breach is not cured
within 30 days after written notice of the breach is delivered to IMDC; or

              v.    IMDC  enters into an agreement with any tissue engineering
or similar company for the development and/or sale of any product related to a
given Product Category while IMDC still retains exclusive license rights to such
Product Category under the terms of this Agreement.

In the event of any of these events, all rights for the particular Product
Category shall revert to ATS upon ATS delivering written notice thereof to
IMDC.

         d.   The effect of any termination of this Agreement (rather than the
termination of IMDC's rights to a particular Product Category) shall be that:

              i.    all license rights granted from ATS to IMDC shall terminate;

              ii.   all payments made by IMDC to ATS shall be retained by ATS
and be non-refundable;

              iii.  all ATS stock issued to IMDC and all stock warrants granted
to IMDC shall remain outstanding and in full force and effect;

              iv.   all intellectual property rights belonging to each party
shall be retained by that party, with neither party having any license rights
to use the other party's intellectual property rights (excepting, however, as
to the regulatory matters as set forth at the end of Section 4(b) above); and

              v.    all claims for damages caused by any breach occurring
prior to the termination shall survive and remain enforceable.

     7.  MISCELLANEOUS.

         a.   This Agreement shall not be terminable due to a change of
control, sale or merger of either ATS, IMDC, or any of their respective
affiliates or subsidiaries.

         b.   The parties agree to use diligent and reasonable efforts to
maintain the confidentiality of any information received from the other party,
and to seek confidential treatment from the SEC of the substantive portions of
all agreements between them.  The parties agree to provide the other party
with a reasonable opportunity to review all press releases relating to the
agreements between them.

         c.   Each party will maintain adequate product liability insurance, at
reasonable levels to be agreed upon from time to time, such that each party
bears responsibility for its own defects and negligence.  ATS will accept
product liability responsibility for any and all defects related to the ATS
manufacturing of products which ATS elects to manufacture.  In the event that
ATS elects not to manufacture, then ATS and IMDC will jointly ensure that the
party who conducts the manufacturing processes will accept responsibility for
its own defects and negligence.  IMDC accepts product liability responsibility
related to promotion of the Product Portfolio.  IMDC shall monitor customer
complaints and will be responsible for corrections, withdrawal or alert notices.

         d.   Any disputes arising from this Agreement (other than validity of
the Intellectual Property Rights) shall be resolved through final and binding
arbitration under the rules of the AAA by one arbitrator in the state and county
of the party which does not originate the request for arbitration.  The
parties will share the costs of the arbitration, and each party will bear its
own expenses unless the arbitrator determines that a party has acted in bad
faith.  The decision of the arbitrator shall be final and non-appealable and may
be enforced in any court

                                    9

of competent jurisdiction.  The parties consent to jurisdiction in any federal
or state court located in Los Angeles, California.

         e.   This Agreement may only be revised in writing, and shall be
governed by California law.  This Agreement may be executed in facsimile
counterparts.  Any notices under this Agreement shall be sent to the executives
and law firms as designated by the parties from time to time.

         f.   This Agreement is not assignable, other than to a party which
acquires substantially all of the assets of the assignor party.

     WHEREFORE, the parties have executed and delivered this Agreement as of
May 10, 1999.
