Abstract:
Four embodiments of videoendoscopic knot pushers are shown having a main body and first and second fingers whose ends are shaped in a smooth rounded shape to guide a suture and knot into position with a patient's body. The finger members define either a "V" shaped cleft or a smooth walled channel between them for grasping the suture. One embodiment of the invention has second and third channels for retaining the suture in the fingers even during retraction of the main body. Another embodiment of the present invention has a spiral channel formed "upstream" of the finger members for retaining control of the suture even if the suture slips out of the grasp of the channel formed by the first and second finger members.
