Claim 8:
9. A shape sensing enabled 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 shape sensing;
a guide wire support rod comprising at least one of strands, braids, and dampening materials configured to provide vibration-dampening features, wherein the guide wire support rod is configured to receive the optical fiber lumen therein to permit rotation and translation of the one or more optical fibers and to protect the one or more optical fibers, wherein: the optical fiber lumen substantially decouples torqueing of the 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; and
an optical shape sensing fiber disposed within a pull wire.
