Einrichtung zur laparoskopischen Implantation einer rückflussverhindernden Prothese

摘要

The prosthesis is a normal C-shaped cushion member (21), the inside diameter of which is generally larger than the normal outside diameter of the distal esophagus. The C-shaped member is temporarily deformable to a shape adapted for inserting the member into the abdominal cavity through a laparoscopic portal. A shaping spring (28) normally maintains the cushion member in the C-shape and is deformable to permit inserting the C-shaped member through the portal. An optical viewing laparoscope is inserted through the abdominal wall of the torso. The prosthesis is temporarily deformed and inserted through a laparoscopic portal in the torso wall. The prosthesis is then positioned around the distal esophagus adjacent the diaphragm.
