Claim Text:
1. A drive assembly for driving an imaging catheter having a rotatable fiber and a rotatable drive shaft, the drive assembly comprising: a fiber optic rotating junction having a stationary portion with a stationary fiber therein and a rotatable portion with a rotatable fiber therein; a first optical connection configured to connect the stationary fiber with a light source; a motor configured to rotate the rotatable portion of the fiber optic rotating junction; a second optical connection configured to connect the rotatable portion of the fiber optic rotating junction with both the drive shaft and the rotatable fiber of the imaging catheter so as to transmit torque from the motor to the drive shaft and the rotatable fiber of the catheter and so as to transmit light from the light source to the rotatable fiber of the catheter; a sensor configured to detect a rotational position of the fiber optic rotating junction; and a processor configured to obtain the detected rotational position and stop the motor only when the fiber optic rotating junction is in a predetermined rotational position.
