Abstract:
1. A medical implant device useful for tissue regeneration, said medical implant device comprising: granules of a calcium-containing, osteoconductive material, said granules having an average maximum particle diameter greater than 0.05 mm and less than about 5 mm; a thin web of biodegradable polymeric material interconnecting said granules and providing said granules and biodegradable polymeric material as an integral, flexible membrane having a first face and a second face, said membrane having an average thickness of about 0.1 mm to 1.5 mm, the thin web of biodegradable polymeric material being a size to wrap around a bone defect and wrap over itself; said first face of said flexible membrane having a nonuniform, proturbant surface protruding greater than 0.1 mm above said thin web of biodegradable polymeric material, said nonuniform, proturbant surface populated with a plurality of the granules oriented such that the plurality of the granules form proturbances presenting exposed regions of calcium-containing, osteoconductive material, said exposed regions of calcium-containing, osteoconductive material separated by regions of said biodegradable polymeric material of said web, and said second face of said membrane having a nonuniform, proturbant surface protruding greater than 0.1 mm above said thin web of biodegradable polymeric material, said nonuniform, proturbant surface of said second face being populated with a plurality of the granules oriented such that the plurality of the granules form proturbances presenting exposed regions of calcium-containing, osteoconductive material, said exposed regions of calcium-containing, osteoconductive material separated by regions of said biodegradable polymeric material of said web.
