5. A method of attaching a prosthesis to the esophagus or cardia, comprising the steps of:
-
providing a prosthesis having at least one cellular ingrowth surface thereon;
preparing a surface of the wall of the esophagus or cardia for attachment to the cellular ingrowth surface by mechanically abrading tissue from the surface of the wall of the esophagus;
contacting the cellular ingrowth surface to the prepared surface, and permitting cellular ingrowth from the prepared surface into the cellular ingrowth surface to attach the prosthesis to the prepared surface. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
