| 16. A method of coating a medical device, comprising:
providing a medical device;
providing a coating material;
applying the coating material to the medical device by cold spray thermal processing wherein powder particles are introduced
into a high pressure gas where both the gas and particles enter a supersonic jet which is directed against the medical device
forming a porous coating, and wherein the medical device is selected from the group consisting of a stent, guide wires, lead
tips, catheters, and markers;
wherein the porous coating is functionally graded,
wherein the thickness of the coating on the medical device is varied, and
applying a drug to the porous coating on the medical device.
