Abstract
The systems and methods described herein include drug delivery catheters that have dimpled porous balloons mounted onto the distal end of the catheter. In one embodiment, the balloons are adapted for delivering therapeutic agents to the tissue wall of a body lumen, and to this end include a plurality of dimples formed in the exterior surface of the balloon, with each dimple having at least one aperture through which a fluid delivered into the interior of the balloon can extravasate. It is understood that the balloons described herein provide, inter alia, increased coverage of the tissue wall to which the agent is being delivered and less traumatic contact between the agent being delivered and the tissue wall.
