Surgical polymer molded and flexible covering material with or without secondary composite additive materials for providing anti-bacterial and tear resistant properties

摘要

A surgically implantable mesh for covering a tear or rupture in a lining associated with an interior body cavity. A mat shaped polymer body has top and bottom spaced apart surfaces which are communicable at intervals by an interior configuration defined in the body and which promotes tissue in-growth following implantation. An antibacterial additive is intermixed with the polymer in a viscous state prior to formation and can included at least one of silver, gold, copper, bronze, or ground bamboo fibers.

1. A surgically implantable mesh for covering a rupture in a lining associated with an interior body cavity, said mesh comprising:
a generally mat shaped, flexible and polymer based body having an upper layer and a lower layer, each of said layers further including a plurality of closed perimeter defining surfaces which create apertures in said layers; said body further including a plurality of elongated and structurally supporting ribs separating said upper and lower layers, said ribs each further including a four sided cross sectional profile; a bottom extending side of the four sided profile of each rib extending along a continuous and structurally supporting inner surface of said lower layer separating said lower layer closed perimeter defining surfaces, said upper layer closed perimeter defining surfaces being arranged in both overlapping and partially offsetting fashion relative to said lower layer closed perimeter defining surfaces to promote tissue in-growth following implantation.
