Title: DRUG DELIVERY CATHETER AND METHOD OF USE THEREOF
Abstract:
A drug delivery catheter includes a shaft, an inflatable inner balloon attached to the shaft. The inflatable balloon has an outer surface coated with a drug or a composition including a drug. The catheter also includes a perforated outer balloon. The perforated outer balloon surrounds the inflatable inner balloon. The perforated balloon has multiple perforations therein. A method of delivering a drug to a treated site using the catheter includes inserting the catheter into a body cavity to dispose the perforated outer balloon in a site to be treated and inflating the inflatable balloon to treat the site and to deliver the drug to at least some regions of the treated site through the multiple perforations. The body cavity may be a blood vessel or any other body cavity.
