Abstract:
An ablation catheter comprising:a probe having a shaft which defines an exterior surface and a channel in at least a portion of the shaft; an electrode carried on the exterior surface of the probe so as to be axially movable relative thereto; an elongate conductor being connected to the electrode and insulation means being provided around the elongate conductor, wherein the insulation means comprises an insulation sleeve axially slidable on the shaft portion, the elongate conductor extending longitudinally between the shaft portion and the insulation sleeve, the insulation sleeve being retractable at least in part into a recess formed in a rearward portion of the probe; the elongate conductor being mounted for axially slidable movement within the channel and extending proximally to a source of energy; and remote-operated actuator means connected to the elongate conductor for axially moving the electrode along the exterior of the shaft portion in response to the actuator means.
