Multifunctional electrosurgical apparatus
First Claim
1. An electrosurgical apparatus for treating tissue comprising:
- an elongate shaft having a proximal region, a distal region comprising a conductive region and one or more lumens therethrough;
one or more apertures defined by the shaft in communication with at least one of said one or more lumens;
a stylet occluding at least a portion of an opening defined by a distal end of said elongate shaft;
an electrical coupling associated with said proximal region for flexibly coupling said shaft to a power source for supplying energy to said conductive region;
a temperature sensor associated with said distal region; and
at least one fluid delivery interface connection flexibly coupled to said proximal region for coupling a fluid delivery mechanism to deliver a treatment composition through at least one of said one or more apertures.

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.
