A covered stent having a framework of interconnected elongated members to the form of a hollow tube. The stent may be a coiled, slotted, self-expanding, etc., and may be metal or a polymer or a combination. A cover is disposed over a portion of the stent, either on the inside surface, the outside surface or intermediate those surfaces. The cover may be a polymer and may be resorbable. The cover can extend over the entire stent or only a portion of the stent and may include one or more drugs or other beneficial active agents and may have properties to prevent permanent occlusion of a side-branch or bifurcation when placed within a branching or bifurcated vessel. |
