Abstract
A method and device handle having a slide assembly are disclosed for controlling rotational speed of a catheter assembly under various rotational loads. The method includes: driving a catheter assembly at a target rotational speed in a first direction; detecting an actual rotational speed of the catheter assembly in the first direction; comparing the target rotational speed and the actual rotational speed of the catheter assembly in the first direction; and stopping the driving of the catheter 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 value over a predetermined time frame.
