A method and apparatus for creating lesions in a tissue comprising a puncturing member and a probe. The puncturing member comprises a body with a proximal portion comprising a hub, a distal portion comprising a conductive tip, and a lumen extending between the proximal and distal portion. The probe comprises a handle at the proximal end and a probe body, wherein the probe body is dimensioned to extend through the lumen of the puncturing member, and wherein the probe body comprises at least one displacement portion that is biased to contact the inner wall of the puncturing member when the probe is inserted into the puncturing member, whereby when the probe body contacts the inner wall, energy is delivered from the probe to the conductive tip of the puncturing member. |
