Patent ID: 8518123

Claim:
A biocompatible implement for bone and tissue regeneration, comprising: a first layered structure and a second layered structure, each having: a bioresorbable polymer carrier layer having opposing, plasma treated, major surfaces, made of a polymer having a resorption rate in an implant site that substantially matches a rate of tissue generation in the layers formed of the bone or tissue forming material; and a bone or tissue forming material layer including nano-sized hydroxyapetite particles and being applied to at least one of the major surfaces of the polymer carrier layer, wherein the bone or tissue forming material layer has at least one side face, and wherein the at least one side face of the bone or tissue forming material layer is at least partially uncovered to allow neo-vascularization when the implement is in contact with an implant surgical site; and a geometric structure layer having a plurality of substantially cylindrical geometric structures and positioned between the bone or tissue forming material layers of the first and second layered structures, wherein the substantially cylindrical geometric structures are aligned parallel to the first and second layered structure, wherein the substantially cylindrical geometric structures each have a bioresorbable polymer layer and a cylindrical bone or tissue forming material, the bioresorbable polymer layer being adjacent to the bone or tissue forming material layers of the first and second layered structures and surrounding the cylindrical bone or tissue forming material.
