Abstract

Methods and apparatus for the repair of sliding hiatal hernias through laparoscopic techniques comprising a tubular sleeve; a conically shaped guide with an essentially pointed forward end positionable within the sleeve; a prosthesis coupled to the guide; and means for securing the prosthesis around the esophagus of a patient immediately beneath the patient'"'"'s diaphragm whereby the prosthesis assumes a generally torus shape. The prosthesis may be pre-inflated and wherein the sleeve is axially splitable after the initiation of insertion of the guide. The prosthesis may be inflatable and further including a hose to inflate the prosthesis after positioning.
