Abstract:
A stent fabrication method comprising the steps of:(a) coating an outer surface of a metallic tubular member with a photo-sensitive resist resulting in a coated tubular member, said metallic tubular member having an outside surface, an inside surface and an inner lumen; (b) placing said coated tubular member in an apparatus which simultaneously exposes a selected portion and shields other selected portions of said outer surface of said coated tubular member to a light source, yielding a partially exposed tubular member; (c) immersing said partially exposed tubular member in said photo-resist developer resulting in a treated tubular member; (d) sealing said inner lumen; and (e) processing said treated tubular member by a chemical or electro-chemical etching process to remove metal located in said selected portions of said tubular member.
