A catheter system for use in minimally invasive cardiac surgical procedures. The catheter system diminishes certain trauma generally associated with invasive cardiac procedures while providing aortic occlusion, extracorporeal circulation, cardiac arrest, and cardiac venting. The catheter system provides a minimally invasive and simplified system that performs total cardiopulmonary bypass with ease of insertion, improved whole body profusion, and shortened recovery periods. The catheters are refined, with reduced diameters and specialized functions for maximum control of each aspect of cardiopulmonary bypass.

Cardiopulmonary catheter system

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.
