An optical catheter system comprising an intraluminal catheter that provides optical signals to a patient and carries optical signals from the patient, an outer housing, and an inner carriage that moves longitudinally relative to the outer housing and rotates relative to the outer housing during operation when the catheter system is being driven by a pullback and rotation system. The optical catheter system has an interlock system that prevents rotation and longitudinal movement of the inner carriage in the outer housing until attached to the pullback and rotation system. The pullback and rotation system comprises a frame and a catheter system interface, attached to the frame, to which the catheter system is coupled. A carriage drive system is further provided that moves longitudinally and rotates relative to the frame to provide rotation and longitudinal drive to the catheter system.

Système de cathéter optique, comprenant un cathéter intraluminal transmettant des signaux optiques vers un patient et recevant des signaux optiques du patient ; un boîtier extérieur ; et un chariot intérieur qui, en pratique, se déplace longitudinalement par rapport au boîtier extérieur et effectue une rotation par rapport à celui-ci lorsque le système de cathéter est actionné par un système de retrait et de rotation. Le système de cathéter optique comprend un système de verrouillage qui bloque la rotation et le déplacement longitudinal du chariot intérieur dans le boîtier extérieur tant qu'il n'a pas été fixé au système de retrait et de rotation. Le système de retrait et de rotation comprend une armature et une interface de système de cathéter, fixée à l'armature et à laquelle le système de cathéter est couplé. Un système d'actionnement de chariot se déplace longitudinalement et effectue une rotation par rapport à l'armature de manière à assurer la rotation et le déplacement longitudinal du système de cathéter.
