Abstract
A multi-lumen aortic balloon catheter is disclosed. The catheter is designed to assist surgeons in more effectively performing cardiovascular surgery, particularly cardiopulmonary bypass (CPB) surgery. In one aspect the catheter is inserted into a femoral artery and threaded through the artery to the aortic arch where it is positioned so that the balloon is positioned in the ascending aorta. When inflated, the balloon (preferably a cylindrical design) blocks the aortic arch between the great arteries and the coronary ostia. A cardioplegia solution is delivered to the heart through an internal lumen in the catheter to slow the heart. Blood from a cardiopulmonary machine is transported through a blood flow lumen of the catheter to be delivered antegrade flow throughout the arteries. The catheter has a distal portion having fewer lumens than are present in a proximal portion. An alternative multilumen aortic balloon catheter is disclosed that is inserted through a patient's aorta.
