Abstract
An ablation catheter including a probe, an electrode mounted on the probe so as to be movable relative thereto, a remote-operated actuator means for moving the electrode, an elongate conductor connected to the electrode and insulation provided around the conductor. The insulation can include a sleeve axially slidable on the probe, the elongate conductor extending longitudinally between the probe and the insulation sleeve and the insulation sleeve being retractable at least in part into a recess formed in a rearward portion of the probe.
Claims3
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;
- a slidable conductor mounted for axially slidable movement within the channel and connected to the electrode and extending proximally to a source of energy;
- and
- remote-operated actuator means connected to the conductor for axially moving the electrode along the exterior of the shaft portion in response to the actuator means.
