A
medical device for treatment of a stenosed body lumen, includes an open-ended cylindrical body carried on a distal end of a
catheter for
insertion of the device into the body lumen and placement at the stenosed site. The cylindrical body is movable between a collapsed position for
insertion into the body lumen, and a radially expanded position pressed against the wall of the body lumen. In one embodiment the body sidewall is formed by a plurality of interconnected struts or elements defining openings therebetween, and at least one elongate ribbon is attached to an outer surface thereof for carrying a therapeutic agent. In another embodiment, the body is formed of interwoven elements defining a mesh-like structure, and the elements may comprise dissimilar materials, such as, e.g.,
copper and silver. In a further embodiment the body is formed of
layers of different materials such as, e.g.,
copper, silver, and / or steel, laminated together. In a still further embodiment the device is designed for temporary placement of the
catheter and body in a body lumen for treatment of a stenosed site, after which the
catheter and body are withdrawn. In all forms the body may have an outwardly flared inlet end to reduce turbulence of fluid flowing through it, and / or a gel-like
coating of a
cholesterol-dissolving or blood clot dissolving agent may be placed on the device.
