Abstract
An apparatus for addressing tissue and bone in a nasal cavity includes a rotary or oscillatory cutting member disposed in the lumen of a shaft. The shaft may have a first window region oriented in first direction and a second window region oriented in a second direction. The cutting member may have a first cutting edge configured to be cyclically moved across at least a portion of the first window region and a second cutting edge configured to be cyclically moved across at least a portion of the second window region. A shield is selectively positionable to occlude the first and to occlude the second window region.
Claims21
1-20. (canceled)
An apparatus comprising:
- (a) a shaft, wherein the shaft comprises a longitudinal axis, wherein the shaft defines a lumen, wherein the shaft comprises a distal portion and a proximal portion, wherein the shaft comprises a first window region and a second window region;
- (b) a first cutting edge disposed in said lumen, wherein the first cutting edge is configured to be cyclically moved across at least a portion of the first window region;
- (c) a second cutting edge disposed in said lumen, wherein the second cutting edge is configured to be cyclically moved across at least a portion of the second window region;
- (d) a first shield portion which is selectively movable relative to the shaft and the first cutting edge between a first position and a second position, wherein the first shield portion is configured to occlude the first window region when the first shield portion is moved to the first position, wherein the first shield portion is configured to not occlude the first window region when the first shield portion is moved to the second position;
- and
- (e) a second shield portion which is selectively moved relative to the shaft and the second cutting edge between a third position and a fourth position, wherein the second shield portion is configured to occlude the second window region when the second shield portion is moved to the third position, wherein the second shield portion is configured to not occlude the second window region when the second shield portion is moved to the fourth position.

An apparatus comprising:
- (a) a shaft, wherein the shaft comprises a longitudinal axis, wherein the shaft defines a first lumen, wherein the shaft comprises a distal portion and a proximal portion, wherein the shaft comprises a first window region and a second window region, wherein the first window region is oriented toward a first direction which comprises a radial directional component, wherein the second window region is oriented toward a second direction which comprises an axial directional component;
- (b) a cutting member disposed in the first lumen, wherein the cutting member comprises a second lumen, wherein the cutting member comprises a first cutting edge disposed in said lumen, wherein the first cutting edge is configured to be cyclically rotated across at least a portion of the first window region, wherein the cutting member comprises a second cutting edge, wherein the second cutting edge is configured to be cyclically moved across at least a portion of the second window region;
- and
- (c) a shield member which is selectively rotatable relative to the shaft and the cutting member between a first position and a second position, wherein the shield member is configured to occlude the first window region when the shield member is rotated to the first position, wherein the shield member is configured to occlude the second window region when the shield member is rotated to the second position.

An apparatus comprising:
- (a) a handle assembly comprising
- (i) a distal end and a proximal end;
- and
- (ii) a suction port which is connectable to a vacuum source;
- (b) a shaft assembly comprising:
- (i) a shaft, wherein the shaft comprises a longitudinal axis, wherein the shaft defines a lumen, wherein the shaft comprises a distal portion and a proximal portion, wherein the proximal portion of the shaft is connected to the distal end of the handle assembly, wherein the shaft comprises a first window region and a second window region;
- (ii) a cutting member disposed in the first lumen, wherein the cutting member is configured to rotate about the longitudinal axis, wherein the cutting member comprises a second lumen which is in fluid communication with the suction port, wherein the cutting member comprises a first cutting edge configured to be cyclically moved across at least a portion of the first window region, wherein the cutting member comprises a second cutting edge configured to be cyclically moved across at least a portion of the second window region;
- and
- (iii) a shield member which is selectively rotatable relative to the shaft and the cutting member between a first position and a second position, wherein the shield member is configured to occlude the first window region when the shield member is moved to the first position;
- wherein the shield member is configured to occlude the second window region when the shield member is moved to the second position.
