Occlusion device and method of performing an anastomosis

摘要

An occlusion device (1) to occlude an opening (78) in the wall of a blood vessel (62) having an occludent member (2) that may be gripped using knots (8) in a thread (4) so that the occludent member (2) can be inserted into the blood vessel (62) through the opening (78). The occludent member (2) has an exterior surface (14) and an interior surface (15). In use, the edge (84) of the opening (78) contacts the exterior surface (14) to thereby occlude the opening (78) and the interior surface (15) is filled with blood flowing in the blood vessel (62). The thread (4) extends from the exterior surface (14) on the exterior of the occludent member (2) for extraction of the occludent member (2) from the blood vessel (62) through the opening (78).
