Anastomosis device and method
First Claim
1. An anastomosis device for use in coupling an end of a graft vessel to a side of a target vessel, the target vessel having an opening formed in a side wall thereof for insertion of the device, the device comprising a tubular member, at least a portion thereof being radially compressible to a compressed state for insertion of the tubular member into the opening in the target vessel, and expandable from the compressed state to an expanded state for engagement of the graft vessel with an inner surface of the target vessel after insertion of the tubular member into the opening in the side wall of the target vessel, the compressible portion of the tubular member having an inner surface and an outer surface defining a wall thickness therebetween, the wall thickness of the compressible portion in its compressed state being less than the wall thickness of the compressible portion in its expanded state.

Abstract
An anastomosis device for use in coupling an end of a graft vessel to a side of a target vessel. The target vessel has an opening formed in a side wall thereof for insertion of the device. The device comprises a tubular member, at least a portion thereof being radially compressible to a compressed state for insertion of the tubular member into the opening in the target vessel and expandable from the compressed state to an expanded state for engagement of an inner graft vessel surface with an inner surface of the target vessel after insertion of the tubular member into the opening in the side wall of the target vessel. The compressible portion of the tubular member has an inner surface and an outer surface defining a wall thickness therebetween. The wall thickness of the compressible portion in its compressed state is less than the wall thickness of the compressible portion in its expanded state.

24. A method for coupling a graft vessel and a target vessel in an end-to-side anastomosis comprising the steps of:
-
providing a graft vessel with a fastener coupled thereto, the fastener comprising a radially compressible portion;
exerting an inwardly directed radial force over at least a portion of the compressible portion until the fastener has an outer diameter smaller than the diameter of an opening formed in a side wall of the target vessel;
inserting at least a portion of the fastener into the opening in the side wall of the target vessel;
and removing the radial force to allow the compressible portion of the fastener to radially expand to sealingly engage the graft vessel with an inner wall of the target vessel. - View Dependent Claims (25, 26, 27, 28, 29, 30)
