ABSTRACT:
Viscerotomy closure devices and methods of use close a hole in a bodily organ, such as one created during a natural orifice transgastric surgery procedure. A mesh with a hole in its center and an attached loop of suture having a Roeder knot is mounted on the protruding rod of an end-to-end anastomosis stapler between the anvil and the staple carrying member. The mesh covers the staple receiving slots. When rotated when in contact with tissue, an augur-shaped blade attached to the anvil's exterior self-feeds the tissue through a notch in the anvil's base into the space between the anvil and the staple carrying member. After the stapler is fired to staple the mesh to the tissue and create a viscerotomy, a knot pusher cinches the loop of suture and subsequently tightens the Roeder knot to maintain the cinch.
