Abstract

A catheter and method of use adapted to intermittently deliver fluids to and drain fluids from a body vessel having an interior lumen occluding balloon. The selective inflation and deflation of the inner balloon controls the occlusion or communication of an inner lumen. The inner occluding balloon is defined between the distal end of the catheter and a proximal lumen opening allowing for the selective isolation of the proximal openings from the catheter distal end. The catheter of the present invention and several methods of use thereof are ideally suited for aortic perfusion and providing myocardial infusion in antegrade fashion using a single lumen. The catheter is further provided with a double lobed outer balloon for selectively occluding the body vessel, such as the aorta, and to provide a bloodless region to complete the proximal end of an anastomosis while perfusing the myocardium to restart the heart.
