Abstract: A cartridge assembly to couple an electrosurgical device to treat tissue with an electro surgical unit includes a cartridge member to operate with a power delivery apparatus of the electro surgical unit and a fluid delivery apparatus of the electro surgical unit. An electrosurgical unit includes a power delivery apparatus and a fluid delivery apparatus arranged to operate with a cartridge member to be located in a cartridge receptacle of the electrosurgical unit. An electrosurgical device includes a first electrode spaced alongside the second electrode, with each electrode having a blade shaped member. Each blade shaped member has opposing sides bounded by edges, with the edges having a medial edge and a lateral edge. At least one fluid outlet is adjacent each blade shaped member, and each fluid outlet is in fluid communication with a fluid passage.

Abstract: In some embodiments, an electrosurgical device includes a shaft, a first U-shaped electrode at a distal end of the shaft, and a second blade shaped electrode at the distal end of the shaft. The second electrode includes a spherical distal end. And the second electrode is substantially coplanar with the first electrode such that the first electrode surrounds a perimeter of the second electrode. The second electrode is spaced from the first electrode by an aperture. In some embodiments, an electrosurgical device includes a shaft, a first electrode at a distal end of the shaft defining an aperture and comprising a pointed tip, and a second electrode disposed at the distal end of the shaft that is substantially coplanar with the first electrode such that the first electrode surrounds a perimeter of the second electrode. The second electrode is spaced from the first electrode by the aperture.

Abstract: 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.
