PROSTHESIS FOR PREVENTING GASTRO-OESOPHAGEAL REFLUX.

摘要

A prosthesis in the form of a flexible tube having a substantially uniform cross-section is disclosed. The prosthesis comprises a flange (2) for endoscopically placing stitches or clips in a hiatal hernia (3), and a flexible tubular portion (1) enabling the tube to be squeezed by exerting a pressure (F) on the outer surface thereof to prevent a reflux of the stomach contents into the oesophagus. Food can pass freely through the prosthesis in the direction from the oesophagus (4) to the stomach (5). Said prosthesis is made of a biocompatible polymer optionally containing barium sulphate to make it detectable using X-rays.
