Patent ID: 8064978

Claim:
A modular catheter, which includes: an elongate tubular member having a proximal end and a closed, distal end with a lumen extending from the proximal end to the distal end and a plurality of electrodes arranged at, or adjacent, the distal end, conductors for the electrodes being contained within a wall of the tubular member; an elongate steering mechanism removably received within the lumen of the tubular member such that a distal end of the steering mechanism is substantially in register with the distal end of the tubular member, wherein the steering mechanism is configured for controlling lateral displacement of the distal end of the tubular member; and a control device having a proximal end and a distal end, the proximal end of the tubular member and a proximal end of the steering mechanism being releasably connectable to the distal end of the control device.
