Abstract
An elongated tubular endoprosthesis or stent is provided which includes a carbon coated surface that is antithrombogenic and helps to restrain the metal body member of the endoprosthesis in the event of a fracture thereof. By providing a suitable underlayer surface to which the carbon coating generally conforms, the stent presents a porous surface to a blood vessel or the like within which it is designed to be implanted. This porous carbon surface promotes ingrowth of tissue thereinto during implantation of the endoprosthesis.
