Patent ID: 7909822

Claim:
A system for shearing and electrosurgically treating tissue, comprising: a debrider apparatus including a first tubular member having a first set of teeth disposed circumferentially around about 25% to about 75% of a periphery of the first tubular member, the periphery adjacent a distal portion thereof, and a second tubular member having a second set of teeth disposed adjacent a distal portion thereof, the second tubular member at least partially disposed within the first tubular member and at least one of the first and the second tubular member being selectively movable relative to the other; and an electrosurgical generator that supplies the first tubular member with a first electrical potential and supplies the second tubular member with a second electrical potential, wherein the first tubular member includes a non-cutting zone disposed circumferentially around about 25% to about 75% of a periphery of the first tubular member.
