Abstract
A catheter for indirect left atrial mapping from the left pulmonary artery is disclosed. The catheter includes an elongated flexible member with a distal end and a proximal end. Located at the distal end is a balloon and an array of mapping electrodes. Located at the proximal end is a manifold to which various ports are secured. In a second embodiment, the catheter differs from the first embodiment in that interspersed within the array of mapping electrodes are defibrillation electrodes. Also, located proximally of the array of mapping electrodes is an array of defibrillation electrodes. In a third embodiment, the catheter differs from the first embodiment in that five defibrillation electrodes are located between the array of mapping electrodes and the balloon. Located proximally of the array of mapping electrodes is an array of defibrillation electrodes.
