Abstract
An endoscopic surgical instrument for passing a suture through tissue includes a first jaw member, a needle, and a capture feature actuable to grip and retain the suture after the suture has been passed through a tissue body. An actuation mechanism can both move the needle between retracted and extended positions, and move the capture feature between open and closed configurations, via a single actuation. The capture feature may be a trap door which is axially translatable relative to the first jaw member to overlap a portion of the first jaw member and trap a portion of the suture between the trap door and the overlapped portion. The first jaw member may be movable relative to a second jaw member to grasp a tissue body. The instrument can grasp a tissue body, pass the suture through the tissue, capture and retain the suture without being repositioned relative to the tissue.
