A method is provided for electropolishing a stent. A stent is mounted on a rack having electropolishing mounts. Each of the mounts has a base and an electrically conductive first member having a first end and a second end. The first end is connected to the base and the second end contacts the external surface of the stent. Each of the mounts also has a non-electrically conductive second member having a first end and a second end. The first end of the second member is attached to the base and the second end is placed in the bore of the stent. The second ends of the first and second members bias towards each other to secure the stent between them. The stent is immersed in an electropolishing bath and an electrical current is applied to the first member.

[ What is claimed is:] [1.]1. A method of electropolishing a stent, comprising the steps of:a) mounting a tubular stent having a longitudinal bore on a rack, said rack having a first end and a second end provided with a plurality of stent electropolishing mounts, each of said mounts having a base; an electrically conductive first member having a first end connected to said base and a second end adapted to selectively contact the external surface of said tubular stent without damaging said external surface; an electrically non-conductive second member having a first end connected to said base and a second end adapted to be selectively disposed within the longitudinal bore of said stent without damaging said longitudinal bore, said first member and said second member further adapted so as to bias said second end of said second member towards said second end of said first member in an amount sufficient to secure said stent between said first and said second members;b) immersing said stent in an electropolishing bath and applying electrical current to said first member for a predetermined period of time; andc) changing the point where said second end of said first member contacts said external surface of said stent prior to the expiration of said predetermined period of time.
