    Abstract: The present invention provides a method for fabricating an implant stent with therapeutic effects. The method of the present invention includes designing and delineating a pattern of the implant stent, drilling a thin metal sheet to form positioning holes, cutting a desired pattern on the thin metal sheet according to the designed pattern, drilling a hole on a line rib of the stent to form a braided structure by a micro discharge processor according to the desired pattern. Then, the stent is cleaned and polished by the electropolish to trim the edge and the rough surface of the stent. Then, the biodegradable material, PLLA, PGA, fibrinogen, the polyurethane-polyethylene oxide mixed with the heparin or the combination thereof, is used for forming the mixed material with the high molecular weight, and is solved in a solvent, wherein another grinded therapeutic drug with the micro or the nano size is added.
