                              TERMINATION AGREEMENT
                                     BETWEEN
                        VISTA MEDICAL TECHNOLOGIES, INC.
                                       AND
                                 MEDTRONIC, INC.


This Termination Agreement is made, effective as of the 27th day of March, 2000,
(the "Effective Date") by and between Vista Medical Technologies, Inc. ("Vista")
and Medtronic, Inc. ("Medtronic"). As used in this Termination Agreement, the
term "Medtronic" shall include Medtronic, Inc. and its subsidiaries, affiliates,
and divisions including Medtronic Sofamor Danek, Inc. ("MSD") (successor in
interest to Sofamor Danek Group, Inc.) and the Medtronic Cardiac Surgery
business unit ("Medtronic Cardiac Surgery").

         Background:


          A.   Vista and Medtronic entered into an Amended and Restated Sales
               Agreement dated June 26, 1998 (the "Cardiac Surgery Agreement")
               by which Medtronic was to distribute Vista products.

          B.   Vista and MSD entered into a Cooperative Technology Agreement,
               effective January 6, 1998, and an Exclusive Distribution
               Agreement, as amended, effective January 6, 1998 (referenced
               jointly as the "Sofamor Danek Agreements"), by which MSD was to
               distribute Vista products.

          C.   The parties now wish to terminate the Cardiac Surgery Agreement
               and the Sofamor Danek Agreements.

In consideration of the mutual promises contained herein, the parties agree as
follows:

1.   TERMINATION OF AGREEMENT. Vista and Medtronic mutually agree that the
     Cardiac Surgery Agreement and the Sofamor Danek Agreements are hereby
     terminated. All provisions relating to protection of intellectual property
     and confidential information shall survive termination of the Agreements.

2.   RESTRUCTURING OF PAYMENT OBLIGATIONS. Upon the termination of the Cardiac
     Surgery Agreement and the Sofamor Danek Agreements, all payment obligations
     between the parties shall cease, provided, however, that the outstanding
     balance of $781,160 which Vista owes Medtronic, will survive, but will now
     be subject to repayment, if at all, solely pursuant to the provisions of
     that certain Transition Agreement which is being entered into by the
     parties simultaneously with this Termination Agreement (the "Transition
     Agreement").

3.   RELEASE.

     a.   Medtronic and Vista, on their own behalf and on behalf of their
          affiliates, subsidiaries, successors, agents, directors, officers,
          employees, and assigns (the "RELEASING PARTIES"), do each hereby
          release and absolutely and forever discharge each other (including
          their present and former shareholders, parent companies, subsidiaries,
          affiliates, predecessors, officers, directors, employees, agents,
          attorneys,


<PAGE>

          successors, and assigns) from any and all claims, demands, damages,
          debts, liabilities, accounts, reckonings, obligations, costs,
          expenses, liens, and causes of action of every kind whatsoever,
          whether now known or unknown, suspected or unsuspected, whether in
          contract, tort, or other cause of action, filed or unfiled, which they
          now have, own, or hold or at any time heretofore ever had, owned, or
          held, or may hereafter own or hold against the other Releasing Parties
          and their present and former shareholders, parent companies,
          subsidiaries, affiliates, predecessors, officers, directors,
          employees, agents, attorneys, legal successors, and assigns which are
          (i) based upon, arise from, or are in any way related to or connected
          with the Releasing Parties' investment or other involvement in Vista
          Medical Technologies, Inc., or (ii) based upon, arise from, or are in
          any way related to or connected with the Cardiac Surgery Agreement or
          the Sofamor Danek Agreements and the parties' performance or
          implementation thereof.

     b.   This Termination Agreement has been voluntarily and knowingly executed
          by the Releasing Parties on advice and with approval of respective
          legal counsel and with the express intention of effecting the legal
          consequences provided by section 1541 of the California Civil Code,
          that is, the extinguishment of obligations as herein designated. The
          Releasing Parties hereby expressly waive any and all rights and
          benefits conferred upon them by the provisions of California Civil
          Code section 1542, which reads:

               A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
               DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
               EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
               AFFECTED HIS SETTLEMENT WITH THE DEBTOR.


     c.   The releases contained in this section shall not apply to claims for
          indemnification (including defense costs) between the parties if, and
          to the extent, the party seeking indemnification has been found to be
          responsible to an unrelated third party for damages which were caused
          by actions taken by the party against whom indemnification is sought
          and which actions are determined to have been intentionally fraudulent
          as to the third party awarded damages or beyond the scope of the
          indemnifying party's express or implied authority. The releases
          contained herein shall not apply to any claims which arise from a
          party's violation of any applicable law, ordinance, or regulation, or
          claims that arise under the Transition Agreement.

     d.   This release does not constitute an admission of liability by any
          party with respect to any matter hereby released.

4.   MISCELLANEOUS.


     a.   GOVERNING LAW. This Termination Agreement shall be governed by and
          interpreted in accordance with the laws of the State of California,
          including all matters of construction, validity, performance and
          enforcement, without giving effect to principles of conflict of laws.

     b.   COMPLETE AGREEMENT. The parties hereto agree and acknowledge that this
          Termination Agreement constitutes the complete agreement between them
          with respect to the matters set forth herein.

<PAGE>


     c.   COUNTERPARTS. This Termination Agreement may be executed in any number
          of counterparts, each of which shall be deemed as original and all of
          which together shall constitute one instrument.

     d.   PUBLIC ANNOUNCEMENT. The parties agree that, except as may be required
          to comply with the requirement of applicable law or any exchange upon
          which such party's capital stock is listed or traded, no press release
          or similar public announcement or communication will be made or caused
          to be made concerning the execution or performance of this Termination
          Agreement unless specifically approved in advance by Medtronic and
          Vista, such consent not to be unreasonably withheld. The foregoing
          shall not restrict either party's communications with employees,
          customers, or private investors.

     e.   ASSIGNMENT. This Termination Agreement shall be binding upon and inure
          to the benefit of the parties hereto and the successors or assigns of
          the parties hereto; provided that (i) the rights and obligations of
          Vista may not be assigned except to any person who succeeds to
          substantially all of the assets and business of Vista to which this
          Termination Agreement relates, and (ii) the rights and obligations of
          Medtronic may not be assigned except to an affiliate of Medtronic or
          to any person who succeeds to substantially all of that portion of
          Medtronic's business to which this Termination Agreement relates.

                                  EXHIBIT 10.2

                              TRANSITION AGREEMENT
                                     BETWEEN
                        VISTA MEDICAL TECHNOLOGIES, INC.
                                       AND
                                 MEDTRONIC, INC.


This Transition Agreement is made, effective as of the 27th day of March,
2000, (the "Effective Date") by and between Vista Medical Technologies, Inc.
("Vista") and Medtronic, Inc. ("Medtronic").  As used in this Transition
Agreement, the term "Medtronic" shall include Medtronic, Inc. and its
subsidiaries, affiliates, and divisions including Medtronic Sofamor Danek,
Inc. ("MSD") (successor in interest to Sofamor Danek Group, Inc.) and the
Medtronic Cardiac Surgery business unit ("Medtronic Cardiac Surgery").

     Background:


     A.   Vista and Medtronic entered into an Amended and Restated Sales
          Agreement dated June 26, 1998 (the "Cardiac Surgery Agreement") by
          which Medtronic was to distribute Vista products.

     B.   Vista and MSD entered into a Cooperative Technology Agreement,
          effective January 6, 1998, and an Exclusive Distribution Agreement, as
          amended, effective January 6, 1998 (referenced jointly as the "Sofamor
          Danek Agreements"), by which MSD was to distribute Vista products.

     C.   By separate agreement being entered into on the same date as this
          Transition Agreement, the parties are entering into an agreement to
          terminate the Cardiac Surgery Agreement and the Sofamor Danek
          Agreements (the "Termination Agreement").

     D.   The parties wish to enter into this Transition Agreement to arrange
          for the disposition of equipment and the continued provision of Vista
          Systems and service to customers after the termination of the Cardiac
          Surgery Agreement and the Sofamor Danek Agreements.

In consideration of the mutual promises contained herein, the parties agree as
follows:

1.   RESTRUCTURED PAYMENT OBLIGATIONS. Upon the termination of the Cardiac
     Surgery Agreement and the Sofamor Danek Agreements pursuant to the
     Termination Agreement, all payment obligations between the parties shall
     cease except for the outstanding balance of $781,160 which Vista owes
     Medtronic relating to reimbursable sales and marketing expenses, which
     balance will be paid, if at all, pursuant to Section 3, Offset of Payment
     Obligation, of this Transition Agreement.


<PAGE>

2.   TRANSITION OF SALES. The parties agree to implement the following sales
     transition plan (the "SALES TRANSITION PLAN") with the mutual goal of
     accomplishing a smooth and cooperative substitution of Vista as the
     Customer contact with regard to Vista Systems:

     a.   CURRENT CUSTOMERS AND PROSPECTS. Medtronic shall list on EXHIBIT A
          those current customers who have purchased or installed Vista Systems
          purchased through Medtronic or MSD (the "CUSTOMERS"). Medtronic shall
          list on EXHIBIT B those potential customers for Vista Systems it has
          identified at the time this Transition Agreement is executed (the
          "PROSPECTS"). Between the signing of this Transition Agreement and May
          1, 2000, the parties will use their best efforts to jointly meet one
          (1) time with each Customer and Prospect for the purpose of
          introducing a Vista representative to the Customer or Prospect,
          discuss any questions or issues the Customer or Prospect has about the
          Vista Systems, and transition the customer relationship to Vista. From
          that meeting forward, Vista will be responsible for all sales and
          marketing contacts with that particular Customer or Prospect. Nothing
          contained in this Transition Agreement shall prevent or prohibit
          Medtronic from taking whatever actions it deems appropriate to meet
          the needs of its customers (including, but not limited to, the
          repurchase of product from customers).

     b.   CUSTOMER REFERRALS. For a period of six months after the Effective
          Date of this Transition Agreement is executed by both parties (the
          "SALES TRANSITION PERIOD"), Medtronic will refer to Vista all
          inquiries it receives from potential customers regarding the purchase
          of Vista Systems ("REFERRALS") and, if reasonably possible, Vista and
          Medtronic will jointly meet one (1) time with each such Referral to
          introduce the Vista sales representatives and commence the sales
          process.

     c.   GRANT OF STOCK FOR POST TERMINATION PURCHASE ORDERS. For each purchase
          order received by Vista from any Customer, Prospect, or Referral
          during the Sales Transition Period ("POST TERMINATION PURCHASE
          ORDERS"), Vista will issue to Medtronic shares of common stock in
          Vista as follows:

          i. Within thirty (30) days after expiration of the Sales Transition
          Period, Vista will issue to Medtronic shares of Vista common stock
          equal to (A) the aggregate revenue from all Post Termination Purchase
          Orders less (B) the aggregate cost of the Vista Systems subject to the
          Post Termination Purchase Orders, divided by (C) the average closing
          price of Vista's common stock for the last 20 days of the Sales
          Transition Period. The aggregate cost of the Vista Systems subject to
          the Post Termination Purchase Orders shall be determined by applying
          the figures identified as Vista Cost in Exhibit E to each element of
          the subject Vista Systems. The maximum value of any common stock to be
          received by Medtronic under this Section shall not exceed $1.0
          million.

          ii. The provisions of this section shall apply to purchase orders
          issued directly to Vista or through a distributor, manufacturer's
          representative, or sales agent during the Sales Transition Period. Any
          commissions paid to such distributor, manufacturer's representative,
          or sales agent in connection with these purchase orders shall be
          deducted for the purposes of calculating aggregate revenue.

<PAGE>

          iii. Medtronic agrees that it will not divest any of its Vista common
          stock, Vista common stock obtained through this Section or otherwise
          in an open market trade for a price of less than $1.75 per share until
          December 31, 2000.

3.   OFFSET OF PAYMENT OBLIGATION. Medtronic will offset the outstanding balance
     owed by Vista to Medtronic set forth in Section 2, above, in an amount
     equal to the value of the common stock granted to Medtronic pursuant to
     Section 3(c), above. In the event Medtronic is granted common stock with a
     value greater than the outstanding balance owed by Vista to Medtronic,
     Medtronic shall not be required to reimburse Vista for the excess. In the
     event Medtronic is granted common stock with a value less than the
     outstanding balance owed by Vista to Medtronic or no common stock at all,
     Medtronic shall release Vista of its obligation to reimburse Medtronic for
     any difference, up to and including the entire outstanding balance
     identified in Section 2.

4.   TRANSITION OF SERVICE. The parties agree that, subject to the following
     service transition plan, Vista shall be responsible for equipment service
     of all Vista Systems and systems which have been placed by Medtronic or
     MSD.

     a.   EXHIBIT C lists the Customers who purchased Vista Systems from
          Medtronic or MSD whose products are currently subject to warranty or
          service agreement obligations.

     b.   For Customers and anyone who purchases Vista Systems after the date of
          this Transition Agreement, Medtronic will continue to provide service
          with personnel in its employ as of the Effective Date until Vista
          assumes responsibility for the service, but in no event longer than
          for three (3) months from the Effective Date. Medtronic shall not be
          required to hire additional personnel to provide this service if
          personnel employed as of the Effective Date voluntarily leave the
          employment of Medtronic or are otherwise available for direct hire by
          Vista. Medtronic will be responsible for the cost of such service
          until April 1, 2000. After April 1, 2000, if Medtronic is still
          providing such service, Vista will reimburse Medtronic for the costs
          of providing service incurred by Medtronic.

     c.   For a total fee of Twelve Thousand Dollars ($12,000), inclusive of
          reasonable travel expenses, payable in advance, Medtronic will make
          the services of Philippe Borremans available to Vista from the date of
          this Transition Agreement through April 30, 2000, for the purpose of
          providing product service to purchasers of Vista Systems.

     d.   To the extent Medtronic is a party to maintenance, lease, or Master
          Usage Agreements with Customers, Medtronic and Vista agree to use
          their best efforts to have such agreements assigned to Vista by
          Medtronic and obtain Customer consent where required. If Customer
          consent is obtained, Medtronic's interest, if any, in that Customer's
          equipment (the "Transferred Equipment") will be transferred to Vista
          and the Customer will pay all subsequent fees to Vista. As long as
          Vista continues to receive revenue from or in connection with the
          Transferred Equipment sufficient to cover its actual costs of
          providing the service on that Transferred Equipment (whether from the
          Customer or otherwise), Vista will reimburse Medtronic for Medtronic's
          unamortized book value in the Transferred Equipment as of the transfer


<PAGE>

          date, if any, which reimbursement will be made on a monthly basis
          depreciating the value on a straight line basis over what would be the
          remaining term of the Customer agreement. If any required Customer
          consent is not obtained, Medtronic and Vista agree that they will use
          their best efforts to arrange for Vista to actually perform the
          service on that Customer's equipment (the "Non-Transferred
          Equipment"). In that event, Medtronic will pay to Vista the fees it
          receives from the Customer; provided, however, that as long as the
          amount paid to Vista is adequate to cover Vista's actual costs of
          providing service on the Non-Transferable Equipment, Medtronic will
          retain the amount needed on a monthly basis to amoritze Medtronic's
          book value in the Non-Transferred Equipment on a straight line basis
          over what would be the remaining term of the Customer agreement.


5.   EQUIPMENT AND INVENTORY. Medtronic agrees to sell to Vista, on an as-is
     basis, any of its inventory of Vista Systems or systems (including parts)
     which Medtronic may own at the time of the request from Vista Medtronic's
     then current book value for such inventory; provided, however, that if
     Medtronic reasonably determines that it will need any such inventory to
     meet its service obligations set forth in Section 4, above, it will not be
     required to sell such inventory to Vista. Exhibit D contains a list of all
     current Medtronic inventory of Vista Systems and parts and their current
     book value.

6.   REGULATORY ISSUES. The specific details on the Regulatory Transition are
     listed on Exhibit F. The parties will cooperate on all regulatory matters
     necessary to allow Vista to assume full responsibility for the sale,
     distribution, and service on Vista Systems world-wide. From the Effective
     Date on, Vista will be responsible for all product reporting, MDR
     reporting, and Vigilance reporting. Medtronic will promptly advise Vista of
     any product related issues it becomes aware of.

7.   MISCELLANEOUS.

     a.   RELATIONSHIP. This Transition Agreement does not make either party the
          employee, agent, or legal representative of the other for any purpose
          whatsoever. In fulfilling its obligations pursuant to this Transition
          Agreement, each party shall be acting as an independent contractor.

     b.   ASSIGNMENT. This Transition Agreement shall be binding upon and inure
          to the benefit of the parties hereto and the successors or assigns of
          the parties hereto; provided that (i) the rights and obligations of
          Vista may not be assigned except to any person who succeeds to
          substantially all of the assets and business of Vista to which this
          Transition Agreement relates, and (ii) the rights and obligations of
          Medtronic may not be assigned except to an affiliate of Medtronic or
          to any person who succeeds to substantially all of that portion of
          Medtronic's business to which this Transition Agreement relates.

     c.   GOVERNING LAW. This Transition Agreement shall be governed by and
          interpreted in accordance with the laws of the State of California,
          including all matters of construction, validity, performance and
          enforcement, without giving effect to principles of conflict of laws.

<PAGE>

     d.   COMPLETE AGREEMENT. The parties hereto agree and acknowledge that this
          Transition Agreement constitutes the complete agreement between them
          with respect to the post-termination matters set forth herein.

     e.   WAIVER AND AMENDMENT. The failure of any party to enforce at any time
          any of the provisions of this Transition Agreement shall in no way be
          construed to be a waiver of any such provision, nor in any way to
          affect the validity of this Transition Agreement or any part hereof.
          Any amendment to this Transition Agreement shall be in writing and
          signed by the parties hereto.

     f.   COOPERATION AND SUBSEQUENT ADJUSTMENT OF EXHIBITS. The parties shall
          execute any and all further documents and take any and all further
          action that reasonably may be necessary or required to effectuate the
          Transition Agreement. If omissions or inaccuracies in the Exhibits are
          discovered after the signing of this Transition Agreement, the parties
          agree that they will negotiate in good faith to adjust the Exhibits to
          reflect the actual subject matter of the Exhibits.

     g.   COUNTERPARTS. This Transition Agreement may be executed in any number
          of counterparts, each of which shall be deemed as original and all of
          which together shall constitute one instrument.

     h.   PUBLIC ANNOUNCEMENT. The parties agree that, except as may be required
          to comply with the requirement of applicable law or any exchange upon
          which such party's capital stock is listed or traded, no press release
          or similar public announcement or communication will be made or caused
          to be made concerning the execution or performance of this Transition
          Agreement unless specifically approved in advance by Medtronic and
          Vista, such consent not to be unreasonably withheld. The foregoing
          shall not restrict either party's communications with employees,
          customers, or private investors.

     i.   ALTERNATIVE DISPUTE RESOLUTION. All disputes concerning the
          interpretation and enforcement of this Transition Agreement shall be
          resolved by negotiations between the parties or, if necessary, by
          mediation, or, if mediation is unsuccessful, by arbitration under the
          procedures of the AMERICAN ARBITRATION ASSOCIATION for commercial
          disputes.
