(57) Abstract: An ablation device includes a handle, an electrode extending from a distal end of the handle, a probe, a thermal sensor, and an energy source. The electrode includes a distal end, a lumen, a coolant inlet conduit, and a coolant outlet conduit. Both conduits extend through the electrode to the electrode distal end. Sidewall ports are formed in the electrodes that are isolated from the cooling medium flowing in the inlet and outlet conduits. The probe is positioned at least partially within the electrode lumen and is configured to be advanced and retracted through the sidewall opening. The thermal sensor is supported by the probe. The electrodes are coupled to an energy source. |
