1. A medical device, comprising:
a multi-core optical fiber including a cladding and one or more core fibers spatially arranged within the cladding, each core fiber of the one or more core fibers including a plurality of sensors distributed along a longitudinal length thereof and each sensor of the plurality of sensors being configured to:
(i) reflect a light signal as reflected light with a different spectral width based on received incident light, and
(ii) change a characteristic of the reflected light for use in determining a physical state of the multi-core optical fiber;
a conductive medium configured to provide a pathway for electrical signals detected at a distal portion of the conductive medium; and
an insulating layer, wherein the multi-core optical fiber is encapsulated in the insulating layer and the conductive medium is encapsulated within the insulating layer.
