Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 1:
2. A shape sensing system, comprising:
a shape sensing enabled medical instrument comprising a guide wire including an outer surface which encapsulates interior features;
the interior features comprising:
an optical fiber lumen configured to receive one or more optical fibers for optical shape sensing;
a guide wire support rod configured to receive the optical fiber lumen therein to permit rotation and translation of the one or more optical fibers,
wherein: the optical fiber lumen substantially decouples torqueing of the medical instrument from twisting the one or more optical fibers, which are rotationally isolated from external torqueing; and the one or more optical fibers are disposed along a central longitudinal axis of the guide wire;
an optical shape sensing fiber disposed within a pull wire; and

a console configured to receive optical signals from the one or more optical fibers and interpret the optical signals to determine a shape of the medical instrument.
