An implantable medical device formed from a drawn refractory metal and having an improved biocompatible surface is described. The method by which the device is made includes coating a refractory metal article with platinum by a physical vapor deposition process and subjecting the coating article to drawing in a diamond die. The drawn article can be incorporated into an implantable medical device without removing the deposited metal.
