Abstract
Abstract An endovascular prosthesis formed of a support member with or without a continuous skin totally encapsulating the support member. The skin can include drugs or other leaching agents, or radiopaque material. A portion of the prosthesis can be tapered to fit within a tapered artery. The prosthesis is particularly adapted for use in small caliber arteries.
