ABSTRACT:

This invention relates to ablation catheters and particularly, but not exclusively, to an ablation catheter suitable for use in medical procedures related to the treatment of heart disease.
For example, the catheter may be used to cause limited and localised damage in cardiac chambers, by employment of radio frequency energy.
WO-A-951875 (FIG. 9) discloses an ablation catheter comprising a hollow sleeve-like probe, an elongate electrode slidably located by the bore of the probe so as to be movable relative thereto, and remote-operated actuator means for moving the electrode axially within the bore of the probe.
According to the present invention, an ablation catheter comprises a probe, an electrode carried by a shaft portion of the probe so as to be movable relative thereto, and remote-operated actuator means for moving the electrode, characterised in that the electrode is slidably mounted on the exterior of the shaft portion, so as to be movable axially relative thereto.
An elongate conductor is preferably connected to the electrode, and insulation means is preferably provided around the conductor.
The insulation means may comprise a tubular sheath which extends substantially from the remote-operated actuator means to the electrode, and is housed in a longitudinal channel in the probe. Axial sliding movement of the electrode is preferably then arranged to be effected by axial movement of the sheathed conductor at the end thereof remote from the electrode.
