  • Method and device for intracorporeal knot tying
    Patent number: 5281236
    Abstract: A method and device for intracorporeal knot tying. The device comprises an elongated, tubular member formed of a shape memory material for carrying a suture thread through an internal passage. A distal end of the tube is formed with a bight. An outer sheath supports the remaining length of the tube. When a knot is to be formed, a free end of the suture is pulled through the preformed bight. The tube and sheath then move relative to each other to straighten the bight and throw off a knot in the suture thread for subsequent tightening.
