Einrichtung zum Verbinden und Schliessen abgetrennter Blutgefässe

摘要

A fastener for closing or connecting blood vessels (21,22) has a plurality of miniature barbs (10,37) which pierce the wall (20,26) of the blood vessel (21,22) and anchor the fastener in place. In one embodiment the fastener is comprised of a male member (2) and a female member (4) which are fastened to blood vessel segments with the miniature barbs (10). The male (2) and female (4) members are joined together by inserting the male member (2) into the female member (4) to form a permanent coupling. In another embodiment the fastener is comprised of a ring (36) with miniature barbs (37) on both surfaces; that is used between the splayed ends of a severed blood vessel (21,22). The device can also be used for opening a blood vessel (51) which has been narrowed by disease or trauma.
