摘要:
The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and method relate to removal of the occluding material from the blood vessels as well as other body lumens. In some variations, the devices include a catheter body, a cutter assembly, a drive mechanism, a torque shaft, a conveyor mechanism, a deflecting mechanism and a torque control device. The deflecting mechanism may be slidable within the catheter body to point the cutter assembly toward a side of a body lumen. The torque control device may sweep the cutter assembly in an arc when the cutter assembly is deflected.
