ELECTROSURGICAL DEVICE WITH A U-SHAPED ELECTRODE AND/OR COPLANAR ELECTRODES

摘要

The invention provides an electrosurgical device and methods of use thereof. In one embodiment, the device may comprise a handle, a shaft distal to the handle, a first electrode tip and a second electrode tip adjacent a distal end of the shaft, with the first electrode tip spaced from the second electrode tip and wherein the first electrode tip comprises a first U-shaped electrode and the second electrode tip comprises a second U-shaped electrode, and at least one fluid outlet. In another embodiment, the device may comprise a handle, a shaft distal to the handle, and a first electrode and a second electrode adjacent a distal end of the shaft with the first electrode coplanar with the second electrode and comprising a wire electrode having a U-shape which surrounds a perimeter of the second electrode and is spaced from the second electrode by an aperture.
