Abstract
Catheter balloon assemblies () for delivering a therapeutic agent to a body vessel are provided, as well as related methods of manufacturing and methods of treatment. The catheter balloon assemblies may include a concentrically disposed dual balloon assembly at the distal portion of the catheter having an inner balloon (), a porous outer balloon () concentrically arrayed around the inner balloon and a catheter shaft () adapted to deliver a therapeutic agent to the body vessel through the apertures in the outer balloon. Radial outward expansion of the inner balloon may urge the outer balloon into contact with the wall of a body vessel, where the therapeutic agent may be delivered from the catheter shaft through apertures in the outer balloon directly to the wall of the body vessel. Preferably, the catheter balloon assemblies include a stiffening' member () within the proximal portion and/or a plurality of lumens lined with a fluorinated hydrocarbon to independently inflate the inner balloon, deliver the therapeutic agent through the outer balloon and house a wire guide (). The catheter balloon assemblies may provide improved tractability and/or pushability characteristics.
