A drive catheter and a motor assembly to energize the catheter. A guidewire is inserted into the vicinity of an occluded blood vessel region and then the drive catheter and motor assembly are slipped over the guidewire. With the guidewire in place the motor is energized and a rotating distal tip portion pushed into contact with blood vessel deposits that block blood flow in the vessel to separate the deposits from the inner wall of the blood vessel.
