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.
