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 methods include providing a vascular device comprising a catheter body, a cutter assembly, a drive mechanism, a torque shaft, a conveyor mechanism, and a deflecting mechanism. The methods may further include operating the drive mechanism to cut occlusive material, operating the deflecting mechanism to deflect the distal end of the catheter body, and rotating the distal end of the catheter body to sweep the cutter assembly.
