Abstract
Catheter balloons () for delivering a bioactive () to a body vessel in a greater amount and/or more quickly are provided, as well as related methods of treatment. The catheter balloon may include a dual balloon assembly at the distal portion () of the catheter having an inner balloon (), an outer balloon () with apertures () concentrically arrayed around the inner balloon, and a catheter shaft () adapted to deliver a carrier () through the apertures of the outer balloon. The bioactive is disposed on a portion of at least one of the inner and outer balloon surfaces. Radial outward expansion of the inner balloon urges the outer balloon into contact with the wall of the body vessel. The carrier is introducible within the catheter shaft to pass through the annular lumen () between the balloons and through the apertures of the outer balloon. The carrier interacts with the bioactive in order to release a therapeutically effective amount of drug to the wall of the body vessel.
