Abstract:
A method for vascular anastomosis of an end of a graft vessel to the wall of a receiving blood vessel comprising:positioning an anvil within a receiving blood vessel with the aid of a positioning stem extending from the anvil within the receiving blood vessel out of an opening such that a user can control the position of the anvil with the positioning stem; piercing the receiving blood vessel with a piercing shaft which extends from the anvil; advancing the piercing shaft beyond the wall of the blood vessel until the surface of the anvil is in contact with the intima of the wall of the receiving blood vessel, attaching an end of a graft vessel to the wall of the receiving blood vessel opposite the anvil, forming an opening in the wall of the receiving blood vessel such that the receiving blood vessel is in fluid communication with the graft vessel, and removing the anvil and the piercing shaft from the receiving blood vessel.
