Abstract
A method for forming an implantable medical device, such as a stent, is provided, in which electric discharges are applied to a metal surface of the implantable medical device. The electric discharges pit the surface. The pitted surface improves retention of a coating on the device and increases the amount of coating that can be carried by the device. An electric discharge machining process is described for applying electric discharges to the surface of the implantable medical device or portion thereof.
