METHODS FOR FORMING POROUS-SURFACED POLYMERIC BODIES ABSTRACT A method of making a polymeric body having a porous surface by a) applying a fluid polymeric composition to a mold surface of a leachable foam having open pores thereon, b) curing the composition to form the polymeric body, and c) leaching the foam from the polymeric body with a suitable solvent which does not dissolve the polymeric body. The method is especially suitable for making porous silicone elastomer bodies by using polystyrene foam as the mold material and the method is useful for forming hollow, porous-surfaced polymeric bodies, e.g. mammary and vascular prostheses.
