1. A medical device including:
a carrier member configured for positioning or implantation in a subject's body, the carrier member including an insertion end and side walls that contact the subject's body during positioning or implantation of the carrier member in the subject's body;
one or more operative components disposed in the carrier member;
an optical fiber at least partly disposed in the carrier member, the optical fiber comprising a core comprising a first cyclo olefin polymer having a first refractive index and a cladding comprising a second cyclo olefin polymer having a second refractive index that is less than the first refractive Index; and
at least one fiber Bragg grating (FBG) sensor array associated with the optical fiber and being disposed in the carrier member,
wherein the at least one FBG sensor array is configured for measuring contact forces at one or both of the insertion end and along the side walls of the carrier member during positioning or implantation of the carrier member in the subject's body.
