TUNA device with integrated saline reservoir

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;
• and
• a discharge member,
• the discharge member comprising proximal and distal portions,
• the proximal portion of the discharge member being in fluid communication with the reservoir,
• the distal portion of the discharge member being in fluid communication with one or both of the lumen of the first needle or the first passageway of the elongate probe member.
• the discharge member being coupled to the actuator such that engaging the actuator forces the conductive fluid to flow from the discharge member to the target location through one or both of the lumen of the first needle or the first passageway of the elongate probe member.
