ABSTRACT:
An electrosurgical apparatus having improved placement accuracy is provided. The electrosurgical apparatus comprises an elongate shaft having a proximal end, a distal end and at least one lumen therethrough, a stylet positioned within a lumen, a conductive tip at the distal end for delivery of energy to the tissue, an electrical coupling at or near the proximal end for flexibly coupling a power source control unit to supply energy to the conductive tip, a fluid delivery connection interface flexibly coupled at or near the proximal end for coupling a fluid delivery mechanism. The apparatus further comprises a temperature sensor. A method of delivering electrical energy to a target treatment area of an animal body is also provided.
