Abstract

A prosthesis and method for treating gastro esophagus reflux. The prosthesis is a normal C-shaped cushion member, 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 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 laparscope 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.

Claims

1. A laparoscopically implantable prosthesis for treating esophageal reflux comprising:

(a) a normally generally C-shaped cushion member, the inside diameter of which is generally larger than the normal outside diameter of the distal esophagus, said normally C-shaped member being temporarily deformable to a shape adapted for inserting said member into a torso cavity through a laparoscopic portal; and

(b) shaping spring means formed with said cushion member to normally maintain said cushion member in said C-shape, said shaping spring means being temporarily deformable, with said C-shaped member to said insertable shape.

2. A method for treating gastro esophageal reflux comprising:

(a) inserting a laparoscopic portal through the abdominal wall of a torso cavity;

(b) inserting an optical viewing laparoscope through said wall, positioned to view the distal esophagus;

(c) applying force to temporarily deform a C-shaped prosthesis to an insertable shape;

(d) inserting said temporarily deformed prosthesis through said portal;

(e) positioning said prosthesis around the distal esophagus adjacent the diaphragm.
