Abstract
The present disclosure relates generally to the field of medical devices and treating tissues within body passages. In particular, the present disclosure relates to electrosurgical devices, systems, and methods for providing treatment of tissue.
Claims20
A surgical system, comprising:
- an elongate tubular body comprising a proximal end, a distal end and one or more working channels extending therebetween;
- a working space expanding system positioned at a distal portion of the elongate tubular body, the working space expanding system movable between a non-expanded insertion position and an expanded position to form an expanded region, the working space expanding system including first and second flexible members and an endcap, the endcap coupled to distal ends of the first and second flexible members;
- a surgical device disposed within a first working channel of the elongate tubular body;
- at least one return electrode disposed on an outer surface of the endcap;
- and
- a power source configured to deliver energy to the surgical device, and in electrical communication with the at least one return electrode.
