BIPOLAR RF ACCESS DEVICE WITH SLIDING AUTOMATIC SHUTOFF CUTTING ZONE

Abstract

An electrosurgical ablation device and associated methods for treating patient tissue are disclosed herein. Example electrosurgical ablation devices of the present disclosure may include an outer sheath having a proximal end, a distal end, a lumen extending therebetween, and an active electrode disposed proximate to the distal end of the outer sheath. Example electrosurgical ablation devices of the present disclosure may further include an access cannula slidably disposed within the outer sheath and having a body composed of an electrically conductive material including an insulating material applied to one or more portions of the body to form one or more shutoff sections and one or more cutting sections. The one or more cutting sections and the active electrode may be adapted to couple to a generator and form a conductive path to ablate tissue.
