A catheter has a balloon electrode assembly with at least one compliant balloon member and at least one electrode carried on an outer surface of the balloon member for accomplishing circumferential sensing or ablation in a tubular region of the heart, including a pulmonary vein or ostium. The catheter may also include an electrode assembly with a tip and/or ring electrode distal of the balloon electrode assembly adapted for focal contact. |
