Abstract
Disclosed in an improved temporary stent and drug delivery catheter, for use in the prevention of restenosis of a dilated vascular region, and/or for use in the delivery of a medication to a preselected vascular site. The catheter comprises an elongate body, a perfusion conduit laterally offset from the axis of the catheter body, and an inflation balloon disposed about the perfusion conduit and at the end of the catheter body. In a drug delivery embodiment, a perforated drug delivery balloon is disposed concentrically about the inflation balloon. A first lumen extends through the catheter body for communicating with the inflation balloon, and a second lumen extends through the body for communicating with the drug delivery balloon. Methods of preventing restenosis during a post procedure observation period and of drug delivery to the vascular intima are also disclosed.
