Abstract
A stent having cavities has been developed that can be quickly and easily used in a wide variety of situations, that keeps vessels open with a minimum degree of recoil and shortening lengthwise, that is flexible and can be delivered to the most distal lesion, and that can continuously deliver anticoagulant or other biologically active agents for an extended period directly at the site of stent placement. The stent of the present invention includes at least one flexible, serpentine backbone, and a plurality of opposing, outwardly-projecting appendages on said backbone, wherein said stent has a substantially circular cross-section.
