ABSTRACT:
The present invention employs ultrasonic energy delivered to myocardial tissue at frequencies sufficient to destroy the myocardial tissue implicated in the arrhythmic. More specifically, the present invention comprises an ultrasonic transducer mounted on a distal end of a catheter and at least one electrode associated with the distal end region of the catheter. The ultrasonic transducer may be a single crystal transducer or a phased array crystal transducer.
