ABSTRACT:
A method for transmyocardial revascularization of the heart of a patient comprises introducing a probe (10) into the thoracic cavity through a percutaneous penetration, a thoracotomy or a sternotomy. An active electrode surface (58) is then positioned adjacent a wall of the patient's heart, e.g., the ventricular wall. Electrically conducting liquid (50) is directed to the heart wall to provide a current flow path and high frequency voltage is applied to ablate or disintegrate tissue at the heart wall. The probe is then axially translated towards the ventricular wall to form a revascularizing channel or artificial vessel from the ventricle to the myocardium to increase blood flow therethrough.
