▎ 摘  要

NOVELTY - Implantable medical device has a porous membrane comprising conductive nanoporous fabric, where the conductive nanoporous fabric having a multiple of pores, each of the multiple of pores having a diameter of less than about 1 micrometer, and a thickness of the conductive nanoporous fabric being greater than the diameter of the multiple of pores, where the porous membrane comprises a multiple of enclosed regions, each of the multiple of enclosed regions configured to contain cells, the porous membrane is configured to be semipermeable to allow diffusion or permeation of bodily fluid to the multiple of enclosed regions to facilitate survival of the cells. USE - Implantable medical device for forming conductive nanoporous fabric. ADVANTAGE - The implantable medical device maintains living cell viability by providing oxygen, or self-cleaning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of forming a conductive nanoporous fabric, which involves: (1) depositing a metal oxide layer on a substrate, the metal oxide layer having a barrier layer in contact with the substrate and a porous layer extending from the barrier layer; (2) depositing a conductive base layer onto the porous template; (3) etching the substrate and the barrier layer to produce a porous template; (4) growing nanowires within each of the multiple of pores to provide a multiple of nanowires; (5) removing the porous template to provide the multiple of nanowires and the conductive base layer; (6) depositing a conductive membrane material between the multiple of nanowires; (7) etching the multiple of nanowires and the conductive base layer to provide the conductive nanoporous fabric.
