A prosthesis for insertion into a lumen to limit restenosis of the lumen. The prosthesis carries restenosis-limiting drugs which elute after the device is positioned in the lumen.
A device for local intralumenal administration of drugs comprising: (a) a catheter having proximal and distal ends; (b) a body including a plurality of support elements forming a open-ended, radially expandable, self-supporting tubular structure having an interior surface and an exterior surface; (c
A device for local intralumenal administration of drugs comprising: (a) a catheter having proximal and distal ends; (b) a body including a plurality of support elements forming a open-ended, radially expandable, self-supporting tubular structure having an interior surface and an exterior surface; (c) at least one flexible, polymeric filament attached to the support elements of the body, at least a portion of the filament exposed at the exterior surface of the tubular body, said body mounted on the catheter at the distal end thereof; (d) means at the proximal end of the catheter to provide sufficient radial expansion of the tubular body to bring the tubular body and polymeric filament into contact with a body lumen at an interior portion of the body lumen to be treated and for releasing the tubular body from the catheter; and (e) a drug compounded into the polymeric filament such that the drug is delivered to the body lumen when the tubular body is radially expanded into contact with the portion of the body lumen to be treated.
