Abstract
The invention relates to coated stents and the method of making them. A stent that is substantially radiolucent is at least partially coated with a radiopaque layer that makes the stent visible under X-ray or fluoroscopy. A protective layer is coated on the stent and the radiopaque layer to protect both from scratches, flaking, and galvanic corrosion, and to improve both blood and bio-compatability.
