1. A medical device system for detecting malposition of a medical device within a vasculature of a patient, the system comprising:
the medical device configured for advancement through the vasculature of the patient, wherein the medical device comprises a multi-core optical fiber having a plurality of core fibers, each of the plurality of core fibers including a plurality of sensors distributed along a longitudinal length of a corresponding core fiber and each sensor of the plurality of sensors being configured to (i) reflect a light signal of a different spectral width based on received incident light, and (ii) change a characteristic of the reflected light signal for use in determining a physical state of the multi-core optical fiber; and
a console including one or more processors and a non-transitory computer-readable medium having stored thereon logic, when executed by the one or more processors, causes operations including:
receiving one or more signals from the medical device representing one or more parameters indicative of a location of a distal tip of the medical device within the vasculature of the patient, wherein the one or more signals correspond to reflected portions of a propagating light signal;
processing the one or more signals to determine the location of the distal tip, and
determining whether the medical device has deviated from a target advancement path and has entered an Azygos vein of the patient based on the one or more signals.
