ABSTRACT:
An ablation apparatus has an introducer including an introducer lumen, a proximal portion and a distal portion. Two or more electrodes are at least partially positionable in the introducer lumen. Each electrode is configured to be advanced from the introducer distal portion in a deployed state into a selected tissue site to define a volumetric ablation volume. A fluid delivery member is positioned on at least a portion of an exterior of one of the electrodes. The fluid delivery member is configured to be coupled to a fluid medium source. A cable is coupled to the electrodes.
