Abstract

A stabilized electrophysiology catheter (4) includes a main body portion (16) and a flexible tip portion (18). A plurality of electrodes (24, 26) are positioned along the tip portion. The tip portion includes a main section (20) and a pre-curved, offset, reverse-angle anchor section (22) at its distal end. The anchor section is shaped to engage with and anchor to a coronary opening, typically the coronary sinus opening (48) in the right atrium or a pulmonary vein opening (82) in the left atrium, for stabilized mapping and ablation of the right atrium or the left atrium. A manipulator wire (36) is used to radially deflect the tip portion in a first direction (40). When introduced through the superior vena cava (46), the tip portion forms a generally J-shape. When introduced through the inferior vena cava (54), the tip portion is deflected more than 360.degree..
