                                 BULLETIN
 
                                                       August 26, 1997
 
                            WHERE'S YOUR MONEY?
 
       It is unconscionable that more than 12 months have passed
     since U.S. Surgical made its first cash offer for all of the
     outstanding shares of Circon Corporation. U.S. Surgical's tender
     offers have received overwhelming support from Circon's
     shareholders. Our last partial offer was oversubscribed by 400%
     and understandably so; SHAREHOLDERS WANT THEIR MONEY.
 
               THE VAST MAJORITY OF SHAREHOLDERS HAVE YET TO
                         RECEIVE ONE SINGLE PENNY
 
                           HOW IS THIS POSSIBLE?
 
       We believe it is because of GREED. We think it is clear that
     Circon's management and Board of Directors don't want to sell
     the Company for fear of losing their jobs and all the executive
     perks.
 
       Instead they adopted a "POISON PILL" which made it
     prohibitively expensive for any bidder to acquire Circon without
     their approval, even if supported by the vast majority of
     shareholders.
 
        TAKE THE FIRST STEP TO ELIMINATE THE OBSTACLE THAT PREVENTS
            YOU FROM MAXIMIZING THE VALUE OF YOUR CIRCON SHARES
 
       You now have an opportunity to take an important first step in
     controlling your destiny by removing the obstacle separating you
     from the cash being offered for your shares by U.S. Surgical.
 
                         VOTE THE BLUE PROXY CARD
 
       The long awaited Circon Annual Shareholders Meeting is
     scheduled for October 6, 1997. Take action against Circon's
     entrenched Board that has ignored the will of the shareholders
     who elected them. Now you can replace two current directors with
     two new directors who are committed to your wishes to sell
     Circon.

 
       Exercise your rights by voting on the enclosed BLUE proxy card
     FOR U.S. Surgical's director nominees and FOR the Maximize Value
     Resolution.
 
                                  On behalf of the Board,
                                  /s/ Leon C. Hirsch
                                  Leon C. Hirsch
                                  Chairman, United States Surgical Corporation
 
 
                                 IMPORTANT
 
            Your vote is important, no matter how many or how few
          Circon shares you own. U.S. Surgical urges you to mark,
          sign, date and return the enclosed BLUE proxy card to
          vote FOR the election of the U.S. Surgical nominees and
          FOR the approval of the Maximize Value Resolution.
 
            If your Circon shares are registered in your own name,
          please mark, sign and date the enclosed BLUE proxy card.
          Return the proxy card to U.S. Surgical, c/o Kissel-Blake
          Inc. in the enclosed envelope in time to be voted at the
          Annual Meeting. If any of your Circon shares are held in
          the name of a brokerage firm, bank, bank nominee or other
          institution on the record date, only it can vote such
          Circon shares and only upon receipt of your specific
          instructions. Accordingly, please contact the person
          responsible for your account and instruct that person to
          execute on your behalf the BLUE Annual Meeting proxy
          card.
 
            Remember--even if you have already tendered your Circon
          shares in U.S. Surgical's Offer, you must vote your
          Circon shares on the enclosed BLUE proxy card to support
          U.S. Surgical's nominees and the Maximize Value
          Resolution.
 
            For additional information please review the Proxy
          Statement of U.S. Surgical dated August 11, 1997.
 
            If you have any questions or require assistance voting
          your Circon shares, please call our proxy solicitors:
