Abstract
A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A ceramic cutting member includes both a cutting window having sharp edges and one or more flutes with cutting burrs circumferentially spaced-apart from the cutting window. An electrode may be placed between a pair of flutes and opposite to the cutting window. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the ceramic cutting member cut bone with the flute(s) and soft tissue with the cutting window. The electrode provides cautery or radiofrequency ablation of tissue when the sleeve and ceramic cutting member are not being rotated.
