Abstract:
A method for impregnating a porous metal pad with a polymer, wherein the method comprises:(a) providing a first sheet of biocompatible metal, a first sheet of heat-resistant releasable plastic film, a sheet of semi-crystalline polymer film, a porous metal pad, a second sheet of heat-resistant releasable plastic film, and a second of sheet of biocompatible metal; (b) creating an abutting arrangement of the sheets and pad such that the biocompatible metal sheets form the outer most layers of the arrangement, and the porous metal pad abuts the polyaryletherketone film; and (c) placing the arrangement into a press for sufficient time and under sufficient temperature and pressure to allow the semi-crystalline polymer film to interpose itself within the porous metal sheet, to form an impregnated porous metal pad.
