Abstract

A system for connecting the end of a graft vessel to the side of a target vessel may include an anvil configured to enter the target vessel through an anvil entry hole in the wall of the target vessel; a holder movable relative to the anvil, where that holder may deploy at least one connector through the graft vessel and into the target vessel at a location spaced apart from the anvil entry hole; and at least one sealer that may be detachably connected to the anvil and/or said holder; where at least one sealer may be configured to substantially close the anvil entry hole in the target vessel. A method for performing anastomosis between a graft vessel and a target vessel may include inserting an anvil through the wall of the target vessel into the lumen of the target vessel from outside of the target vessel through an anvil entry hole; connecting an end of the graft vessel to the side of the target vessel with a plurality of connectors at a location spaced apart from the anvil entry hole; creating an opening in the side of the target vessel, where the opening is located within a perimeter defined by the connectors and spaced apart from the anvil entry hole; withdrawing the anvil thr…
