II. Field of the Invention
The present invention is directed generally to an improved catheter for use in the field of cardiac arrhythmia ablation. More particularly, the invention is directed to the use of a rotating tip deflectable catheter system with greatly increased catheter tip maneuverability in the lateral plane, i.e., perpendicular to the catheter shaft, and especially when operating in the ventricular chambers. This allows the operator to direct the tip of the catheter in multiple directions and maneuver the catheter as close as possible to the site of the arrhythmogentic tissue to accomplish effective mapping and ablation.

Normal cardiac pacing, in a healthy heart, is controlled by a special structure known as the sinoatrial node (SA node). This is the natural pacemaker of the heart and is a specialized tissue located within the muscle walls of the right atrium. The SA node provides impulses which dominate the inherent or natural rhythmic contractions of the heart atria and the ventricles. This dominance or control involves the transmission of ionic impulses through cardiac conduction pathways in the atria and the ventric
