Abstract
An implantable prosthesis, for example a stent, is provided that is capable of being loaded with substances. In one example, the prosthesis is a cylindrical-shaped body having depots or pores formed thereon. The depots can be formed at preselected locations on the body of the prosthesis and can have a preselected depth, size, and shape. The depots can have various shapes including a cylindrical or a conical shape. Substances such as therapeutic substances, polymeric materials, polymeric materials containing therapeutic substances, radioactive isotopes, and radiopaque materials can be deposited into the depots.
