Claims16
A method of treating gastroesophageal reflux disease, comprising the steps of:
- providing a prosthetic gastroesophageal valve having an anchor and a valve releasable attached to the anchor;
- positioning the valve assembly at about the base of the esophagus;
- contacting the anchor to the wall of the esophagus or cardia to permit cellular ingrowth through the wall of the anchor.
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.
