Zusammenfassung:A tissue treatment device includes a sleeve assembly having an outer sleeve and an inner sleeve co-axially and rotatably received in an axial lumen of the outer sleeve. A tapered ceramic member has a cutting window formed on a side surface thereof and is attached to a distal end of the outer member. A distal electrode has at least one serrated electrode surface disposed along at least one axially aligned edge and is disposed in the cutting window of the tapered ceramic member so that said at least one serrated electrode surface passes across the cutting window as the inner sleeve rotated in the outer sleeve. A hub is attached to a proximal end of the sleeve assembly and is configured to be detachably received in a motorized handle.
