| 1. A method of chemically etching a metallic member to form an intravascular stent, comprising:
applying a photoresistive coating to a metallic surface of the metallic member;
selectively removing portions of the photoresistive coating from the metallic surface thereby providing exposed portions of
the metallic surface and protected portions of the metallic surface;
exposing the metallic surface to a chemical etchant solution thereby removing a full thickness of the metallic member to form
a pattern generally corresponding to the exposed portions of the metallic surface;
removing the photoresistive coating; and
electrochemically polishing the metallic member in a solution having at least an acid and a corrosion inhibitor.
