Micro-fabrication of bio-degradable polymeric implants

摘要

Various methods of micro-fabricating 2-dimensional and 3-dimensional medical devices comprised of bio-degradable materials. The various methods use conventional photo-lithographic techniques commonly used in the semi-conductor or integrated circuit industry and translate those techniques to process bio-degradable medical devices. The devices may be active, passive or combination active-passive devices for controlling the release of drugs or other bio-active agents contained within the devices. Such devices may be used externally or internally for drug delivery, wound healing, tissue re-generation or the like.
