Abstract
A means and method for sutureless surgical anastomosis. A heat shrinkable sleeve is placed around two tubular members to be anastomosed and then shrunk to engage and maintain the two tubular members in an anastomotic relationship. The ends of the tubular members are everted over rigid or semi-rigid ferrules placed on the ends of the tubular members.
