Abstract
The disclosure relates to systems and methods for irrigated bipolar radiofrequency ablation. The system includes an ablation probe that includes an elongate inner electrode assembly and an elongate outer electrode assembly. An irrigation path for irrigation fluid flow is defined between the outer surface of the inner electrode assembly and the outer surface of the outer electrode assembly. The irrigation path enables cooling fluid to be circulated within the probe body, cooling the outer electrode during ablation.
