Abstract
A method for making an implantable medical device from a drawn refractory metal which has an improved biocompatible surface. The method includes coating a refractory metal article with platinum by a physical vapor deposition process and subjecting the coated article to drawing in a diamond die. The drawn article can be incorporated into an implantable medical device without removing the deposited metal.
