ABSTRACT:
An implantable medical device such as an intraluminal prosthetic device is formed by an improved manufacturing process. A generally cylindrical mandrel is provided. A reverse image of the prosthesis is engraved into a portion of the mandrel. The reverse image of the prosthesis defines voids and raised surface areas in the mandrel portion. A prosthesis-forming metallic medium is electrochemically deposited into the reverse image of the mandrel. The metallic medium may be a metal, metal alloy or a metal compound. The mandrel including the prosthesis-forming medium thereon is further processed to separate the prosthesis formed by the prosthesis-forming medium from the mandrel by dissolving the mandrel. The process provides greater design freedom in the formation of flexible expandable stents.
