ABSTRACT:
A two-sheet fascial expander prosthesis for temporary use and method of using it to treat abdominal hypertension and associated organ system function impairment, in which each flat sheet is attached to the fascia only at opposite sides of an incision. One side of each sheet is armed with mating fastening elements that bond when united to bring about high tensile shear strength and low tensile peeling-off resistance permitting easy separation for diagnostic and therapeutic abdominal entry. The invention is useful because it expands the fascia and adds compliance to the envelope of the abdominal cavity by bridging the gap between free borders of the incised fascia containing intra-abdominal organs without strangulating their blood supply and retaining some tension on the fascia to prevent retraction and bringing the edges closer together as healing progresses, and permitting final removal of the patch and fascia-to-fascia closure. The method of producing and testing biocompatibility of the two-sheet fascia prosthesis also is disclosed.
