Abstract
Molded orthopaedic implants include at least one mesh substrate having opposing upper and lower primary surfaces. At least a major portion of the mesh substrate lower primary surface is integrally moldably attached to the molded implant body. The mesh substrate has at least one selectively exposed region devoid of molded material that exposes at least a portion of the mesh substrate upper surface to at least a partial thickness of the mesh substrate so as to allow for tissue in-growth in the at least one exposed region of the mesh substrate.
Claims35
A molded orthopaedic implant comprising at least one mesh substrate having opposing upper and lower primary surfaces, wherein at least a major portion of the mesh substrate lower primary surface is integrally moldably attached to the molded implant body, wherein the mesh substrate has at least one selectively exposed region devoid of molded material that exposes at least a portion of the mesh substrate upper surface to at least a partial thickness of the mesh substrate so as to allow for tissue in-growth in the at least one exposed region of the mesh substrate.
A method of fabricating an implantable prosthesis, comprising:
- placing an inferior mesh layer on a floor of a three-dimensional mold;
- introducing moldable material into the mold;
- placing a superior mesh layer on a top surface of the moldable material in the mold;
- heating the mold with the moldable material to a desired temperature so that the mold is heated for a desired time;
- then
- forming a molded implant body formed by the heated moldable material whereby the mesh layers are integrally moldably attached to the molded body formed by the moldable material;
- and
- selectively exposing at least one of the inferior and superior mesh layers so that at least one region is substantially devoid of the moldable material whereby the exposed region promotes tissue in-growth therein while at least a major portion of the mesh layers are integrally moldably attached to the molded body.
