ABSTRACT:
A method for bonding a layer of porous polymeric material to a rigid implantable portion of a prosthetic device, which includes the steps of (a) forming a substrate by coating the implantable portion with material which is chemically compatible with the porous polymeric material and which has a melt viscosity and/or melting temperature lower than that of the porous polymeric material, (b) covering the substrate with a porous polymeric material in powder form capable of forming said porous polymeric layer for forming a composite coating on the implantable portion, and (c) heating the substrate and porous polymeric material to a temperature high enough to cause the substrate material to flow into the adjacent pores and low enough so that the porous material will maintain its shape so that the porous layer will be bonded to the substrate and the outer pores will be open to accommodate tissue ingrowth, and an apparatus formed by said method.
