Electrosurgical devices and methods of use thereof

摘要

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.

主权项

1. An electrosurgical device comprising:
an elongate shaft having a longitudinal and axis and a distal end; a first U-shaped electrode at the distal end of the shaft, the first U-shaped electrode being substantially situated in a plane that is substantially parallel to the longitudinal axis of the shaft; a second electrode at the distal end of the shaft comprising a spherical distal end; and at least one fluid outlet, wherein the at least one fluid outlet is spaced said first electrode; the second electrode being substantially coplanar with the first electrode such that the first electrode surrounds a perimeter of the second electrode, and the second electrode being spaced from the first electrode by an aperture.
