Anastomosis device and method
First Claim
1. An anastomosis device for use in coupling a graft vessel to a side of a target vessel, the target vessel having an opening formed in a side wail thereof, the anastomosis device comprising:
- a graft vessel having an end portion and a proximal portion;
a coupling member attached to the graft vessel;
a flexible tube attached to the coupling member; and
wherein the graft vessel extends through the flexible tube, a free end of the graft vessel is evened over and coupled to at least a portion of the coupling member, the coupling member is radially compressible to a compressed state for insertion of at least a portion of the coupling member and at least a portion of the end portion of the graft vessel into the opening of the target vessel, and the coupling member is positionable within the opening of the target vessel when the coupling member expands from the compressed state to an 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.

21. An anastomosis device for use in coupling a graft vessel to a side of a target vessel, the target vessel having an opening formed in a side wall thereof, the anastomosis device comprising:
-
a graft vessel having an end portion and a proximal portion; a coupling member attached to the graft vessel; a flexible tube at least partially disposed about the graft vessel and attached to the coupling member; and wherein a free end of the graft vessel is evened over and coupled to at least a portion of the coupling member, the coupling member is radially compressible to a compressed state for insertion of at least a portion of the coupling member and at least a portion of the end portion of the graft vessel into the opening of the target vessel, and the coupling member is positionable within the opening of the target vessel when the coupling member expands from the compressed state to an expanded state.
