Summary:An electrosurgical device having a tubular outer shaft and an inner shaft is disclosed. The tubular outer shaft includes an axis and a distal end region. The distal end region includes a distal-most tip and a cutting edge defining a window in the outer shaft proximal along the axis to the distal-most tip. The inner shaft inner shaft coaxially maintained within the outer shaft such that the inner shaft is movable about the axis with respect to the outer shaft and wherein a portion of the inner shaft is exposed in the window of the outer shaft. A first electrode is disposed on the outer shaft in a region proximal along the axis to the window, and a second electrode is electrically isolated from the first electrode and disposed on the inner shaft. The second electrode is exposed in the window of the outer shaft.
