Abstract:
1. An apparatus for use with an endoscopic applicator, the endoscopic applicator including a shaft having a proximal end and a distal end and an active electrode having a tip and being adapted for coupling to an electrosurgical generator and extending through the shaft for effecting at the tip thereof an electrosurgical procedure, the apparatus comprising: a support member having a distal end and a proximal end configured to be coupled to an external surface of the shaft; a first sensor disposed on the distal end of the support member and for outputting a first signal indicative of current measured at a distal end of the active electrode; and a second sensor disposed on the proximal end of the support member and for outputting a second signal indicative of current measured at a proximal end of the active electrode, wherein a difference value of the first and second signal is indicative of leakage of current within the shaft.
