摘要: A method and apparatus (10) is used for molding a polymeric article such as a prosthesis (12) which has a solid polymeric portion (14) and a porous polymeric portion (16) for permitting the ingrowth of living tissue within the pores of the portion (16) to anchor the prosthesis (12) within the tissue. The porous polymeric portion (16) is placed within a die cavity (23) and a liquid polymer is introduced into the die cavity (23) to form the solid polymeric portion (14). The liquid polymer also flows into at least a portion of the pores of the porous polymeric portion (16) and forms an integral solid portion (14) and porous portion (16) upon cooling of the liquid polymer.
