Optical Fiber-Based Medical Device Tracking and Monitoring System

A catheter placement system, comprising:

• a catheter including a lumen extending between a proximal end and a distal end of the catheter;
• a stylet removably inserted into the lumen of the catheter, the stylet including a core wire and an optical fiber secured in a longitudinal notch of the core wire, and the optical fiber including a first plurality of optical-fiber-based strain sensors disposed along a first longitudinal portion of the optical fiber and a second plurality of optical-fiber-based strain sensors disposed along a second longitudinal portion of the optical fiber;
• a light source operably connected to the stylet, the light source configured to produce outgoing optical signals incident on the first plurality of optical-fiber-based strain sensors and the second plurality of optical-fiber-based strain sensors;
• a photodetector operably connected to the stylet, the photodetector configured to receive return optical signals from the first plurality of optical-fiber-based strain sensors and the second plurality of optical-fiber-based strain sensors;
• a console including memory and a processor configured to:
• process optical data from the return optical signals;
• and
• map the catheter in accordance with various aspects of the stylet including a location of the stylet within a body of a patient;
• and
• a display configured to display information relating to the various aspects of the stylet including an image of the catheter mapped on the body of the patient.
