Abstract
A steerable catheter suitable for radiofrequency ablation of cardiac tissue comprises a catheter shaft with a deflectable tip at the distal end of the shaft. The tip is deflected by means of a shapable handle coupled to pull wires fastened to the distal end of the deflectable tip. A core wire extends from the handle to the distal tip, providing fine positioning of the deflectable tip by applying torque through the core wire to the tip. A spring tube is further provided in the deflectable tip for improved torque transmission and kink-resistance. The catheter has an electrode at the distal end of the deflectable tip for positioning at a target site and applying RF power to accomplish ablation.
