Abstract
This invention relates to balloon catheters for use in infusing a solution into a body passageway, and their methods of use and manufacture. Each catheter contains at least one lumen through which a solution flows into the body. The balloons of each catheter are secured to the proximal end of the catheter, and each have a plurality of protuberances projecting outwardly from the outer surface of the balloons for the purpose of firmly gripping the walls of the body passageway so as to secure placement of the catheter within the passageway. A malleable wire assists in retaining the catheter in position within the body passageway. A double balloon catheter allows sealing of the body passageway to be accomplished separately from securely gripping the walls.
