A catheter for facilitating intracardiac atrial defibrillation includes an elongated flexible member that has a proximal end and a distal end. The flexible member further has a plurality of lumens that extend from the proximal end to the distal end thereof. An opening is formed through the flexible member adjacent the distal end thereof. One of the lumens communicates with the opening. A balloon envelope is secured to the periphery of flexible member and surrounds the opening. Connected to one end of the lumen associated with the opening is an air inlet tube. A syringe is provided to supply air through the inlet tube, through the lumen and out the opening in order to inflate the balloon envelope. A plurality of spaced apart electrode bands are secured around the periphery of the flexible member in a predetermined pattern. A plurality of electrical leads extend through the proximal end of the flexible member and through corresponding lumens to supply electrical current to the electrode bands.
