Abstract

An ablation balloon catheter probe is described with a first balloon sized to inflate for pressing against an ostial and/or atrial surface surrounding a pulmonary vein, and a second balloon or balloon assembly, distal to the first, sized to inflate and anchor within the pulmonary vein. Optionally, either or both of the balloons comprise a ring of spaced electrodes configured for RF ablation to form a complete ablation scare around the ring.
