Abstract

An endoscopic insertion device for inserting an anastomosis ring having two unitary members in an anatomic tubular body member comprises an anastomosis ring adapter for mounting the unitary members in an engaging position, an inserter for inserting the ring adapter in the tubular body member, and an actuator for actuating the adapter to close the anastomosis ring. A method of using the endoscopic insertion device includes the steps of inserting the anastomosis ring in an engaged position into the tubular body member, securing opposite ends of the tubular body member to the engaged anastomosis ring, applying a biasing force to close the anastomosis ring, releasing the biasing force, and axially withdrawing the insertion device from the closed anastomosis ring.
