ANASTOMOSIS DEVICE AND METHOD OF USING THE SAME

摘要

The present invention provides an anastomosis device which includes an elongate center pin having proximal and distal ends. The proximal end is configured to be graspable using a grasping tool. A grip mechanism is located at the distal end for crimping a suture. The device includes an outer sleeve having a passageway therethrough to receive therein the elongate center pin. A suture having a suture needle is attached to a first end of the center pin and a second end of the suture is formed into a pre-formed knot mounted on the sleeve. The device includes a suture release mechanism having a passageway extending therethrough to receive the outer sleeve therein. The suture release mechanism slides along the sleeve between a first position in which the suture release mechanism is spaced from the distal end and a second position such that movement of the suture release mechanism from the first position to the second position dislodges the pre-formed knot off the sleeve. A free end of the suture, which was attached to a suture needle but cut lose after the suture has been passed through the tissue being sutured, is crimped by the crimp mechanism. The pre-formed knot is dislodged such that the crimped end of the suture is located within the pre-formed knot and pulling the suture through the knot tightens the pre-formed knot on the suture.
