  • Drug delivery and dilatation catheter having a reinforced perfusion lumen
    Patent number: 5421826
    Abstract: An improved 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, an inflation balloon disposed about a catheter body. In a drug delivery embodiment, a perforated drug delivery balloon is disposed concentrically about the inflation balloon. In another embodiment, the two balloons are heat sealed together at the distal and proximal ends of the catheter body. 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 describing the intraluminal delivery of drugs to a site specific location are also disclosed, including the delivery of a drug to a vascular area before, during or after a conventional PTCA procedure.
