An electrophysiology catheter includes a flexible shaft with one or more electrodes disposed at a distal end having a preformed curve. A first steering apparatus allows altering a curvature of the distal end and a second steering apparatus allows steering of the distal end without significantly altering the curvature of the distal end. The first and second steering apparatuses are used for maneuvering the catheter and providing positive contact between the distal end and the tissue targeted for treatment.
