Abstract
A system for mechanical cutting and radiofrequency (RF) treatment of bone and soft tissue includes a probe and an RF power supply. The probe includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member formed of a dielectric material is mounted on the elongated sleeve, and a metal electrode is attached to a surface of the cutting member and configured to deliver RF current. The RF power supply generates current having a pulsed RF waveform and may be connected to the metal electrode to deliver the current having the pulsed RF waveform to the tissue. The use of a pulsed RF waveform reduces a thermal stress on the dielectric material at the interface of the metal electrode and the dielectric material of the cutting member.
