Abstract
An intravascular imaging system includes a catheter with an elongate outer sheath and a torque cable axially translatable and rotatable in the elongate outer sheath, a pullback and rotation unit for axially translating and rotating the torque cable, a sensor configured to provide an output indicative of an axial force exerted by the torque cable on a rotor in the pullback and rotation unit, and a controller configured to cause the pullback and rotation unit to operate in a remedial mode if the output exceeds a predetermined threshold.
