Abstract:
1. A product of manufacture comprising an internal cavity having an inner wall and an outer wall, the product of manufacture further comprising: (a) a thermoplastic polymer comprising a plurality of nano-imprints, wherein at least a portion of the plurality of nano-imprints are formed using a pair of nano-imprint stamps, wherein the first of the pair of nano-imprint stamps faces the inner wall and the second of the pair of nano-imprint stamps faces the outer wall, wherein at least a portion of the plurality of nano-imprints each have a re-entrant pore geometry that is formed using a process comprising a warm compression of the thermoplastic polymer; and (b) a biocompatible surface layer deposited on at least a portion of the thermoplastic polymer, wherein the biocompatible surface layer comprises any of a metal, a metal alloy, a stainless steel, and a ceramic, wherein the biocompatible surface layer includes a plurality of nanotubular structures that each have a diameter of approximately 5 to 1000 nanometers (nm).
