Patent ID: 7322974

Claim:
A device for ablating a tissue at a target location, comprising: a housing; an elongate probe member extending from the housing, having proximal and distal ends, and being provided with a first passageway extending at least substantially from the proximal end to the distal end; a first ablation needle having proximal and distal ends and a lumen extending at least substantially from the proximal end to the distal end, and being slidably disposed within the first passageways of the elongate probe member; a reservoir capable of holding a conductive fluid, and being in fluid communication with one or both of the lumen of the first needle or the first passageway of the elongate probe member; and an actuator coupled to the reservoir and configured to cause the conductive fluid to flow through one or both of the lumen of the first needle or the first passageway of the elongate tubular member into the target location, and coupled to the proximal end of the first needle and configured to cause the distal end of the first needle to extend into the target location.
