                    UNITED STATES SURGICAL CORPORATION
                  FILES SUIT AGAINST CIRCON CORPORATION 

                NORWALK, CT. -- United States Surgical Corporation
      (NYSE:USS) said today that it has filed suit against Circon
      Corporation (NASDAQ: CCON) asking the Court of Chancery in the
      State of Delaware to order Circon to hold its 1997 Annual
      Meeting of Shareholders.

           In addition, USS today reinstated its lawsuit in the Court
      of Chancery seeking to compel Circon to provide USS with
      information necessary to enable USS to communicate directly
      with Circon's shareholders concerning its tender offer and
      proxy contest to elect two directors to Circon's board and
      seeking approval of a shareholder resolution at the Annual
      Meeting.  USS has repeatedly requested this information from
      Circon, but Circon has not yet provided all the requested
      information.

                United States Surgical Corporation is a diversified
      surgical products company specializing in minimally invasive
      technologies that improve patient care and lower health costs.
