ABSTRACT:
A steerable catheter comprises an elongated flexible member that has a proximal end and a distal end. The flexible member further has a plurality of lumens which extend from the proximal end to the distal end thereof. In one embodiment, a stylet is slidably receivable in one of the lumens and has a bent portion formed along the length thereof. The bent portion causes a segment of the flexible member in contact with the same to bend. In a second embodiment, the stylet is straight and the flexible member has a bent portion. In yet another embodiment, both the stylet and flexible member include a bent portion. A plurality of electrodes are secured around the periphery of the flexible member in a predetermined pattern. A plurality of electrical leads extend through the proximal end of the flexible member and through a corresponding one of the plurality of lumens. The electrical leads are adapted to supply electrical current to the electrodes.
