Abstract
A drug delivery device () includes expandable element () formed of a braided structure having a body portion () and first and second end cones (). The end cones are attached at their necks () to a catheter assembly (). The expandable element () can expand to a vessel contacting configuration, in which the body portion () contacts the vessel wall. Bioactive agent () covers at least the outer surface of the body portion () such that bioactive material can be administered to a vessel wall. The end cones () have an open structure allowing unrestricted passage of blood through the device () in the deployed configuration, such that blood flow can be maintained during the administration of bioactive agent () from the device (). The expandable element () can be radially contracted by extending it in the longitudinal direction, both for deployment endoluminally to the treatment site and also for retrieval following the administration of the bioactive material.
