1. An implantable prosthesis for repairing a tissue or muscle wall defect located near the esophagus, the implantable prosthesis comprising:
- a layer of repair fabric that is susceptible to the formation of adhesions with tissue and organs, the layer of repair fabric including first and second surfaces and at least one fabric edge extending from the first surface to the second surface, the first surface adapted to face the tissue or muscle wall defect when the implantable prosthesis is placed in a patient near the esophagus, the second surface adapted to face away from the tissue or muscle wall defect and toward the patient'"'"'s cavity viscera, the layer of repair fabric having an opening that is adapted to receive the esophagus;
a surface barrier that inhibits the formation of adhesions with tissue and organs, the surface barrier being disposed on at least a portion of the second surface of the layer of repair fabric to inhibit the formation of adhesions between the portion of the second surface and adjacent tissue and organs when the implantable prosthesis is placed in the patient; and
at least one edge barrier that inhibits the formation of adhesions with tissue and organs, the at least one edge barrier extending about at least a portion of the at least one fabric edge to inhibit the formation of adhesions between the portion of the at least one fabric edge and adjacent tissue and organs.

Abstract
An implantable prosthesis is provided for repairing or augmenting anatomical weaknesses or defects, and is particularly suitable for the repair of soft tissue and muscle wall openings. The prosthesis is configured to promote enhanced tissue ingrowth thereto, while limiting the incidence of post-operative adhesions between the fabric and tissue or organs. The prosthesis may include a layer of fabric that is constructed and arranged to allow tissue ingrowth and is susceptible to the formation of adhesions for tissue and organs. One or more barriers may be provided on selected portions of the fabric to inhibit the formation of adhesions with tissues and organs. The prosthesis may have an opening that is adapted to receive the esophagus or other tube-like structure, or other projection, that passes through an opening in or projects from a tissue, muscle or organ wall requiring repair and/or augmentation. The prosthesis may be configured for use in hiatal hernia repair and/or treatment of GERD. A method is also provided for the treatment of GERD.
