Abstract
A method of treating cardiac arrhythmias by ablating a portion of the myocardial fibers within a pulmonary vein. Myocardial fibers within a pulmonary vein are located and ablated to block conduction of electrical signals to the heart from ectopic foci within the pulmonary vein. The myocardial fibers are located and selectively ablated so as to avoid having to create a circumferential conduction block around the pulmonary vein or ostium. Devices for locating the myocardial fibers, selectively ablating such fibers, and directing ablative energy, are also disclosed.
