A bipolar electrosurgical instrument for transecting tissue, and a method for use of the same are provided. The instrument includes an introducer having a channel therein extending from an opening at a distal end thereof, an electrically conductive snare slidably positioned within the channel and slidable between an undeployed position wherein it is substantially retracted within the channel and a deployed position wherein a distal portion of the snare extends outwardly from the channel. The electrically conductive snare is substantially insulated substantially along its length but for a predetermined exposed section, and has an active and a return electrode exposed through said exposed section. The instrument further includes a retention element at a distal end of the snare for securing the distal end of the snare to the introducer to thereby form a looped configuration of the snare, and at least one fluid delivery channel extending through the introducer between a fluid inlet sand a fluid outlet at the distal end of the introducer and located in proximity to the exposed section of the snare.
