Abstract
A tissue treatment device has a shaft assembly including an outer sleeve and an inner sleeve. The inner sleeve is co-axially and rotatably received in an axial passageway in the outer sleeve. A dielectric housing has an outer cutting window forming a distal portion of the outer sleeve, and a distal portion of the inner sleeve forms an RF electrode and has an inner cutting window formed therein. The outer and inner cutting windows have outer and inner cutting edges disposed to close together as the inner sleeve is rotated relative to the outer sleeve.
