Abstract: An endoscopic forceps is disclosed including an end effector assembly having two jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween. Each of the jaw members is connectable to an electrosurgical energy source for conducting energy through tissue held therebetween. The jaw members are biased to the first position. The end effector assembly of the endoscopic forceps further includes a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the jaw members and operatively associated with the other of the jaw members. In use, withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to a second position and clamping of the tissue between the jaws.
