Abstract
A fastener suitable for anastomosis procedures may include a base, at least two sharp tines extending from the base, and at least one blunt wing extending from the base. The base may have a perimeter, and the tines and the wings may be arranged in alternating sequence along that perimeter. A method for performing anastomosis between a graft vessel and a target vessel, may include stapling the end of the graft vessel to the side of the target vessel, and deploying at least one fastener into tissue at least at one end of the anastomosis, wherein the fastener includes a plurality of tines and at least one wing, wherein each wing compresses the wall of the graft vessel against the outer surface of the target vessel without penetrating either of the graft vessel and the target vessel.
