Abstract

A catheter having an elongate shaft including a proximal and a distal end. The shaft includes a conductor. An electrode is disposed at the distal end of the shaft and is connected to the conductor. The electrode has a generally annular, cross-sectional shape. The annular shape defines an opening within the electrode. An insulator surrounds the conductor. In accordance with the method of the present invention, a crater wound can be formed through the endocardium and into the myocardium of a patient's heart. Collateral damage to the myocardium can be made by infusing pressurized fluid into the crater wound.
