Abstract: The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.

Abstract: Certain embodiments of the present disclosure provide a thermally robust laser probe assembly. The probe assembly comprises a cannula through which one or more optical fibers extend at least partially for transmitting laser light from a laser source to a target location. The probe assembly also comprises a lens housed in the cannula and a protective component at a distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component, and wherein the distal end of the cannula is sealed at a sealing location of the probe assembly.
