Introduction of two new laparoscopic nooses

Two devices for the temporary occlusion of tubular structures are introduced. They are constructed by combining a double-looped suture with a catheter segment. By this means, a terminal noose is created that can temporarily and atraumatically engage a vessel or other tubular structure. These devices can be used to obtain proximal and distal control of short segments without the need for bulky laparoscopic instruments in the operative field. The devices do not require purchase of any major equipment and can be made with any large-gauge polyfilament suture material and catheters available in the operating room.
