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.

Multi-electrode balloon catheter with circumferential and point electrodes

One embodiment includes a cardiac ablation system, including an ablation probe including at least one ablation application element to ablate tissue in a chamber of a heart of a living subject, a tracking module to track a position of the at least one ablation application element within the heart, a memory to store a map of the chamber of the heart and store a different, respective default ablation-parameter set for each different region of the chamber, and processing circuitry to segment the map of the chamber into the different regions, receive a user input indicative of commencement of an ablation procedure, identify, responsively to the tracked position, a region of the chamber with which the at least one ablation application element is in contact, retrieve the respective default ablation-parameter set assigned to the identified region, and apply the retrieved default ablation-parameter set in controlling the ablation procedure.
