Abstract: Drug delivery systems for delivering a therapeutic agent to a lumen while allowing for fluid perfusion. An illustrative drug delivery system may comprise an inner elongate shaft extending from a proximal end to a distal end and including a lumen extending from the proximal end to the distal end thereof and an outer elongate shaft extending from a proximal end to a distal end and including a lumen extending from the proximal end to the distal end thereof. The outer elongate shaft may be disposed over and axially movable relative to the inner elongate shaft. A self-expanding drug delivery device may include a plurality of longitudinally extending struts and may be movable between a radially collapsed configuration and a radially expanded configuration. A drug coating may be disposed on at least a portion of a radially outward surface of the longitudinally extending struts.
