Abstract
A method for manufacturing an endovascular support device comprises positioning a generally tubular member made of an implantable metal and having a generally cylindrical wall in a working relationship with a laser beam. A desired pattern is cut in the generally cylindrical wall in order to produce a stent having a plurality of openings and a plurality of edges. The stent is tumbled in a medium to round its edges and, in turn, to produce more rounded cross-sections of stent elements.
