Abstract: Embodiments of the invention described herein thus provide implants and methods for manufacturing an implant having an outer cortical layer that is porous. The porous outer cortical layer can help encourage tissue ingrowth into the implant. The porous outer cortical layer may be positioned around a core structure this is solid or that has a hollow interior. The core structure may be spherical or any other appropriate shape for a medical implant.

Abstract: Embodiments of the invention described herein thus provide systems and methods for ear restoration surgery. Certain embodiments provide an improved framework that provides enhanced cooperation between an ear base and a rim.

Abstract: A rotor for flotation machines or flotation cells of flotation machines includes blades that are configured to provide improved bubble flow and bubble generation performance while also reducing the power requirements for rotating the rotor to generate bubble flow within a tank of a flotation cell used to generate froth. Embodiments of the rotor may also be configured to be smaller than conventional rotor designs, which may help reduce the costs of manufacturing the rotor or flotation machines using such embodiments of the rotor.

Abstract: Embodiments of the invention described herein thus provide systems and methods for providing improved surgical implants. Embodiments of the implants may include a thin porous sheet formed on a mandrel. The porous sheet that is formed has an interconnected pore structure that may be compressed by a heat compression mold without losing porosity. Additional membrane materials or other layer materials may be applied to one of the face surfaces of the porous sheet or to one of the edges of the porous sheet. For example, a solid membrane surface may be compressed, bonded, welded, or secured a surface face or an edge of the porous sheet. The solid membrane may be compressed or laminated to the upper surface, lower surface, or both. The solid membrane may be welded to at least one edge of the porous sheet (by, for example, being butt welded, thermally bonded, or heat compressed to the at least one edge).

Abstract: A composite surgical implant that is made of a planar sheet of a thermoplastic resin that includes a top surface, a bottom surface, and a surgical grade metal mesh or metal plates contained therein. The implant may be bent by hand, wherein upon the displacement of the implant, the implant will generally maintain the shape to which it has been displaced.
