Abstract
Abstract A surgical instrument for anastomosis of first and second blood vessels is provided having a handle and a body portion extending distally from the handle. A fastener support is mounted adjacent a distal end portion of the body portion. A plurality of surgical fasteners are releasably supported by the fastener support at the distal end thereof. The surgical fasteners each have a leg with an atraumatic tip. A fastener camming member is mounted adjacent the fastener support. The fastener camming member and fastener support are relatively slidable in response to actuation of the handle to simultaneously deform the surgical fasteners to secure the first and second vessels without piercing the vessels.
