Abstract: A system having an electrode probe and a temperature sensing device, wherein the temperature sensing device is positionable within the electrode probe. The probe can have an elongate electrode body, at least two electrode contacts disposed on the electrode body, and a lumen defined within the electrode body, and the temperature sensing device can have an elongate outer body having a lumen, an elongate inner sensing body disposed within the lumen, and at least one temperature sensor disposed on the elongate inner sensing body. The system in certain embodiments can also have a controller configured to receive temperature information from the temperature sensing device and use the temperature information to adjust energy supply to at least one of the at least two electrode contacts.
