Abstract:
1. A method of performing anastomosis between a graft vessel and a target vessel, each having a circumferential wall and a lumen therethrough, the method comprising: providing an anastomosis tool including a tissue effector and a fluid-driven actuator operationally connected to said tissue effector, wherein said tissue effector includes an anvil connected to a connector holder, and wherein said connector holder includes two arms spaced apart along at least part of their length; connecting said fluid-driven actuator to an energy source; sliding at least part of said anvil through an anvil entry hole in the wall of the target vessel; creating at least one flap in an end of the graft vessel; placing the end of the graft vessel in proximity to the wall of the target vessel; actuating said fluid-driven actuator to connect the end of the graft vessel to the wall of the target vessel; removing said anvil outward through the anvil entry hole in the wall of the target vessel; and closing the anvil entry hole by deploying a sealer in proximity to the anvil entry hole.
