1. A device for local intralumenal administration of drugs comprising:

  • (a) a catheter having proximal and distal ends;

    (b) a first body in the form of an open-ended, radially expandable, self-supporting tubular structure, said first tubular body mounted on the catheter at the distal end thereof;

    (c) a second body having a polymer with a drug compounded therein, the second body in the form of an open-ended, radially expandable tubular structure having an interior surface and an exterior surface, at least a portion of the polymer exposed at the exterior surface thereof, said second tubular body mounted on the catheter at the distal end thereof;

    (d) means at the proximal end of the catheter for radially expanding the first and second tubular bodies to bring the self-supporting structure of the first tubular body into coaxial supporting contact with the interior surface of the second tubular body such that the polymer exposed at the exterior surface of the second tubular body contacts an interior portion of the body lumen to be treated.
