Abstract
An arthroscopic tissue resecting probe includes an elongated shaft having outer and inner sleeves which are formed from an electrically conductive material extending about an axis to a working end. Outer and inner resecting windows are formed in the sleeves in the working end. The working end includes a ceramic body having a collar portion extending fully around a region of the outer sleeve proximal to outer resecting window. A radiofrequency (RF) electrode is disposed on an outer surface of the ceramic body and is spaced-apart from the outer resecting window.
