Claim Text:
1. A device for creating an arteriovenous (AV) fistula, comprising: an elongate member; a distal member having a tapered distal end, connected to the elongate member and movable relative to the elongate member; a first heating member disposed on a blunt tapered face of one of said movable distal member and said elongate member; a second heating member disposed on a blunt tapered face of the other one of said movable distal member and said elongate member; a plurality of physically separate protruding elements disposed circumferentially around a periphery of said one of the first and second heating members; wherein one of the first and second heating members is actively energized to apply heat energy to tissue, and the other of the first and second heating members is a passive non-energized heat conductive surface for promoting heat transfer through a coapted tissue interface from the active heating member to the passive heating member, the heating members being adapted to cut through tissue to create the fistula.
