OPTICAL CATHETER AND PULLBACK AND ROTATION SYSTEM AND METHOD

摘要

An optical catheter system comprising an intraluminal catheter that provi des optical signals to a patient and carries optical signals from the patien t, an outer housing, and an inner carriage that moves longitudinally relativ e to the outer housing and rotates relative to the outer housing during oper ation when the catheter system is being driven by a pullback and rotation sy stem. The optical catheter system has an interlock system that prevents rota tion and longitudinal movement of the inner carriage in the outer housing un til attached to the pullback and rotation system. The pullback and rotation system comprises a frame and a catheter system interface, attached to the fr ame, to which the catheter system is coupled. A carriage drive system is fur ther provided that moves longitudinally and rotates relative to the frame to provide rotation and longitudinal drive to the catheter system.
