Claim Text:
1. A device for creating an arteriovenous (AV) fistula, comprising: a proximal base having a distal tapered end surface; a distal tip connected to the proximal base and movable relative to the proximal base, said distal tip having a proximal tapered end surface; a first heating assembly comprising an energized heating element disposed on at least one of said distal tapered end surface or said proximal tapered end surface; and a second heating assembly comprising a passive non-energized heat spreader disposed on another of said distal tapered end surface and said proximal tapered end surface, the passive non-energized heat spreader includes a raised outer rib along an outer-most peripheral edge of the passive non-energized heat spreader, the raised outer rib forming a pocket in a center portion thereof; wherein the distal tapered end surface and the proximal tapered end surface are adapted to contact opposing sides of a tissue portion to create the AV fistula.
