Abstract
An anastomotic connector comprises a vessel anchor, a midgraft connector and graft material. The vessel anchor has a generally tubular main body including a distal end and a proximal end, the distal end defining a plurality of flanges integrally formed with the tubular main body and being movable from a first loaded position to a second expanded position. The midgraft connector operably couples the graft to the vessel anchor to form an anastomotic connector between an artery and a vein.
