Abstract
One embodiment of the present invention is directed to a method of heating the inner lining of a lumen or cavity of a patient. In this embodiment, the method includes the use of a bipolar electrosurgical instrument which includes a flexible elongated tube having a proximal and a distal end, a first balloon electrode attached to the distal end of the flexible elongated tube, a first electrode in electrical contact with the first balloon electrode through a conductive fluid, a return balloon electrode spaced proximally from the first balloon electrode and a return electrode in electrical contact with the second electrically conductive fluid. In one embodiment, the first balloon electrode and the return balloon electrode include expandable sleeves formed from an electrically insulating material and conductive fluid disposed in the expandable sleeve. In the method according to this embodiment the first balloon electrode and the return balloon electrode are placed in contact with the inner lining of the lumen or cavity, the return balloon electrode is positioned proximal to the first balloon electrode and the first electrode and the return electrode are connected to a source of bipolar energy.
