Noise Suppression System and Method in Catheter Pullback and Rotation System
First Claim
1. An intraluminal optical analysis system comprising:
- an intraluminal optical catheter that provides optical signals to a patient and carries optical signals from the patient to enable analysis of tissue within the patient;
a rotation system including a frame and a carriage drive system that rotates relative to the frame to provide rotational drive to the optical catheter;
an optical source for generating the optical signals; and
a delivery channel for transmitting the optical signals to the intraluminal optical catheter via the carriage drive system through a rotary optical joint.

Abstract
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. A longitudinal drive system has a drive motor for advancing and/or withdrawing the carriage drive system and a manual drive input enabling a user to manually advance or withdrawal the carriage drive system. A latching system holds the carriage drive system when the catheter system is being attached to the pullback system.
