ABSTRACT:
Methods of manufacturing prosthetic devices for use as an artificial meniscus are disclosed. In some embodiments, the methods include injection molding a resilient core material, tensioning reinforcing fibers around the injection molded core, and injection molding an outer layer to embed the reinforcing fibers within the prosthetic device. In some instances the core material is a polycarbonate polyurethane and the reinforcing fibers are made of ultra-high molecular weight polyethylene (UHMWPE) having a lower melting temperature than the polyurethane. In one particular embodiment, the core material is Bionate 80A and the reinforcing fibers are made of Dyneema. In other embodiments, methods for manufacturing a reinforced material for use in prosthetic devices is disclosed.
