Abstract
A device handle is disclosed for cutting substances inside a body lumen, the device handle includes a motor configured to impart a rotational force to a drive shaft assembly and a processor, wherein the processor is configured to: control a driving of the drive shaft at a target rotational speed in a first direction; detect an actual rotational speed of the drive shaft assembly in the first direction; compare the target rotational speed and the actual rotational speed of the drive shaft assembly in the first direction; and stop the driving of the drive shaft assembly in the first direction before a completion of predetermined number of rotations in the first direction when the actual rotational speed decreases a predetermined percentage over a predetermined time frame.
