Abstract
The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to controlled removal of the occluding material from the blood vessels as well as other body lumens. The atherectomy devices have features to convey the materials away from the operative site without the need to remove the devices from the body lumen. Additional aspects include controlled rates of tissue removal as well as other safety features to prevent accidental cutting of the lumen wall.
