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.
1. An electrosurgical device having less than three electrodes, the device comprising: a handle;a shaft distal to the handle having a longitudinal axis and a distal end;a first electrode and a second electrode adjacent the distal end of the shaft, each electrode having a proximal portion, the first
1. An electrosurgical device having less than three electrodes, the device comprising: a handle;a shaft distal to the handle having a longitudinal axis and a distal end;a first electrode and a second electrode adjacent the distal end of the shaft, each electrode having a proximal portion, 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, and wherein the U-shape of the first electrode is substantially situated in a plane that is substantially parallel with the longitudinal axis of the shaft; at least one fluid outlet, wherein the at least one fluid outlet is s aced from said first electrode; andwherein the proximal portions of the first and second electrodes are fixed relative to the distal end of the shaft. 2. The device of claim 1 wherein: the second electrode comprises a wire electrode having a linear segment. 3. The device of claim 1 wherein: the second electrode comprises a wire electrode having a U-shape. 4. The device of claim 1 wherein: the second electrode comprises a blade shaped member. 5. The device of claim 1, wherein the first and second electrodes do not include any outlet for fluid. 6. The device of claim 1 wherein the at least one fluid outlet is separate from said first electrode and said second electrode. 7. The device of claim 1 wherein: the first electrode and the second electrode are formed from metal wire. 8. The device of claim 7 wherein: the metal wire is single strand wire. 9. The device of claim 7 wherein: the metal wire is circular wire. 10. The device of claim 7 wherein: the metal wire is stainless steel wire. 11. The device of claim 1 wherein: the at least one fluid outlet is located at a distal end of the shaft. 12. The device of claim 1 wherein: the electrodes are substantially coplanar. 13. The device of claim 1 wherein: the device is configured to operate as a bipolar device and as a monopolar device.
