Abstract
The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to removal of the occluding material from the blood vessels as well as other body lumens. In some variations, the devices comprise a catheter body, a cutter assembly, a drive mechanism, a torque shaft, and a deflecting mechanism. The deflecting mechanism may be slidable within the catheter body to point the cutter assembly toward a side of a body lumen.
