Pulmonary artery catheter for left and right atrial recording
First Claim
1. A left pulmonary artery catheter for mapping activity in the left atrium comprising:
- an elongated flexible member having a proximal end and a distal end;
a balloon located at said distal end of said flexible member;
an array of mapping electrodes located at said distal end of said elongated member and proximally of said balloon, said array including three pairs of electrodes; and
five defibrillation electrodes interspersed among said pairs of mapping electrodes.

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.
