Abstract

A bipolar electrosurgical instrument including an introducer having a channel therein and 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 along its length but has an active and a return electrode exposed through a predetermined 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 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.
