Abstract

A drug coating is formed by vaporizing a drug in a deposition chamber having an implantable medical device such as a stent loaded therein. A vacuum is utilized to lower the pressure within the deposition chamber, thereby reducing the temperature necessary to vaporize the drug. The drug is then deposited onto the implantable medical device while in a vapor phase to form the drug coating.
