Triple array defibrillation catheter and method of using the same
First Claim
1. A method for facilitating intracardiac atrial defibrillation in a patient comprising the steps of:
- providing a unitary elongated flexible member with a proximal end and a distal end and first, second, and third spaced apart electrode arrays secured around the periphery of said flexible member wherein said electrode arrays are arranged in a predetermined pattern;
positioning said elongated flexible member within the patient'"'"'s heart;
positioning said first electrode array within the superior vena cava, positioning said second electrode array within the right atrium, and positioning said third electrode array within the coronary sinus; and
applying electric shocks through said elongated flexible member in order to defibrillate the patient'"'"'s heart.

Abstract
A catheter for facilitating intracardiac atrial defibrillation that includes an elongated flexible member that has a proximal end and a distal end is disclosed. Three spaced apart electrode arrays are secured around the periphery of the flexible member in a predetermined pattern so that a first electrode array is positioned within the superior vena cava, a second electrode array is positioned within the right atrium, and a third electrode array is positioned within the coronary sinus. Alternatively, the third electrode array may be positioned in the right ventricle rather than the coronary sinus. Electrical leads extend through the proximal end of the flexible member to supply electrical current to the electrode arrays, thereby defibrillating or cardioverting the heart.
