Abstract
A tissue resecting device includes an outer sleeve having an axial bore extending along a longitudinal axis from a proximal end to a distal end and opening to an outer window near the distal end. An inner sleeve is rotatably received in the axial bore of the outer sleeve and has an axial channel adapted for communication with a negative pressure source. A distal housing is attached to a distal end of the inner sleeve and has an annular dielectric portion and a circumferentially adjacent annular metal portion having an inner window with circumferentially spaced-apart sharp cutting edges that opens to the axial channel. An active electrode is carried by the annular dielectric portion, and the inner window is circumferentially spaced-part from the active electrode so that the inner window and the active electrode rotate alternately into alignment with the outer window as the inner sleeve is rotated within the outer sleeve.
