Claim 19:
20. An electrosurgical device for surgically cutting and sealing tissue comprising:
an outer shaft comprising a lumen and a distal end comprising a cutting edge forming an outer shaft window;
an inner shaft rotatably disposed within the lumen of the outer shaft, the inner shaft having a distal portion comprising an inner shaft cutter forming an inner shaft window;
a fluid passage defined between the outer shaft and the inner shaft, the fluid passage being open to a fluid distribution point located proximal the outer shaft window; and
first and second electrodes that are electrically isolated from one another and positioned at a distal end region of the electrosurgical device;
wherein the electrosurgical device is configured to provide:
a cutting state that cuts tissue at an operative site with the inner shaft cutter and the outer shaft cutting edge by moving the inner shaft relative to the outer shaft, and
a hemostasis state that achieves hemostasis at the operative site by arranging the electrosurgical device in a closed position in which the inner shaft cutter is shielded, RF energy is supplied to the first and second electrodes while the electrosurgical device is in the closed position to apply RF energy to tissue of the operative site, and fluid is dispensed from the fluid distribution point and across at least one of the first and second electrodes,

wherein the second electrode is exposed in the window of the outer shaft in the closed position, and
wherein the electrosurgical device is configured such that the second electrode is covered and not exposed in an open position.
