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.
Claims3
A method of treating cardiac arrhythmias, comprising:
- locating myocardial fibers within a pulmonary vein;
- and
- ablating regions of said pulmonary vein containing said myocardial fibers so as to prevent conduction of electrical signals by said myocardial fibers, said ablated region being less than one half the circumference of said pulmonary vein.
Dependencies are inferred from the claim text.
