Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned. In particular, disclosed herein is a drug delivery device comprising a balloon-expandable intraluminal stent, and a pharmaceutical agent-containing coating, wherein the coating comprises a biocompatible polyfluoro copolymer that comprises about eighty-five weight percent vinylidinefluoride copolymerized with about fifteen weight percent hexafluoropropylene and a pharmaceutical agent intermixed with said polyfluoro copolymer. |
