                             IT'S TIME FOR A CHANGE
 
                                                              September 4, 1997
 
Dear Fellow Circon Shareholders:
 
When the Board of Directors you elected at Circon to manage YOUR Company:
 
 . blatantly defies the desire of the overwhelming majority of Circon's
  shareholders to sell the Company--IT'S TIME FOR A CHANGE.
 
 . places their interests above yours--IT'S TIME FOR A CHANGE.
 
 . denies you of the opportunity to more than double the value* of your Circon
  investment--IT'S SURELY TIME FOR A CHANGE.
 
 
              ONLY YOU CAN EFFECT CHANGE VOTE THE BLUE PROXY CARD
 
 
  As Circon's shareholders, we are faced with an important decision. We are
strapped with a Board of Directors led by Richard Auhll, Chairman and
President, which, in our opinion, has failed in its fiduciary responsibility to
act in the best interest of all Circon shareholders. We believe Mr. Auhll and
his Board are letting greed cloud their judgment.
 
  Mr. Auhll and his Board have repeatedly resisted U.S. Surgical's cash offers
for Circon during the last 13 months in spite of the overwhelming support of
Circon's shareholders. The Board's negative actions since our original $18 cash
offer has cost Circon's shareholders dearly in lost opportunities. Shareholders
could have more than doubled the value of their Circon investment had the Board
not resisted our original cash offer. ENOUGH IS ENOUGH! IT IS TIME TO TAKE
MATTERS INTO OUR OWN HANDS BY REPLACING BOARD MEMBERS WHO ARE NOT RESPONSIVE TO
SHAREHOLDER WISHES WITH NEW DIRECTORS WHO WILL BE.
 
  At Circon's Annual Meeting of Shareholders on October 6, 1997, send a message
to Mr. Auhll and the Board that you will no longer tolerate their nonsense and
delay. Show the Circon Board that you demand that they comply with their
fiduciary responsibilities and the will of a majority of Circon's shareholders
to sell the Company to the highest bidder. Return the enclosed BLUE proxy card
today.
 
                                     (OVER)

 
  We urge you to vote FOR U.S. Surgical's two Director nominees and FOR the
Maximize Value Resolution on the BLUE card.
 
  Thank you for your consideration and continued support.
 
                                         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 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.

  *PLEASE EXAMINE THE FACTS:
 
   FACT: The average closing price of Circon's shares was $9.83 during the
   ten days prior to the initial offering on August 2, 1996.
 
   ASSUMPTION: If Circon's Board approved our initial $18 cash offer, the
   proceeds would have been available for reinvestment on September 9, 1996,
   10 days after the expiration of the offer.
 
   FACT: On September 9, 1996, the Dow Jones Industrial Average was 5659.
 
   ASSUMPTION: If Circon's shareholders reinvested the proceeds from the sale
   of their Circon shares on September 9, 1996 in an investment that mirrored
   the Dow Jones Industrial Average's performance, which closed at 7867 on
   September 4, 1997, their reinvestment would have grown 39% or $7.02 per
   share. $7.02 plus the $18 tender offer equals $25.02 per share. Since
   Circon's shares were worth approximately $9.83 before our cash offer, and
   $25.02 after the offer, Circon's shareholders could have grown the value
   of their investment by 155% before taxes.
