Abstract: The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

Abstract: An example laser probe comprises one or more fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the one or more fibers along at least a portion of the laser probe at or near the distal end of the laser probe. The laser probe further comprises one or more lens elements, where each lens element is fused to or formed directly on the distal end of a corresponding one of the one or more fibers. In some embodiments, the laser probe is a multi-fiber, multi-spot laser probe, e.g., comprising four or more fibers and four or more corresponding lens elements.

Abstract: An example multi-fiber, multi-spot laser probe comprises a plurality of fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the plurality of fibers along at least a portion of the laser probe at or near the distal end of the laser probe, where a distal end of each of the plurality of fibers is angle-polished so that the distal end of each fiber is angled relative to a longitudinal axis of the cannula and relative to a plane perpendicular to the longitudinal axis of the cannula. Additional embodiments employ lensed fibers, a distal window, ball lens, lens array, or faceted wedge.

Abstract: Provided herein is an illuminated microsurgical instrument system and an illuminated microsurgical instrument. In one implementation, the system includes a microsurgical instrument having a distally projecting tubular member arranged to perform a medical procedure at an interventional site. The tubular member has a distal tip and an outer surface, the outer surface having a flat surface formed therein. The instrument includes a sheath member surrounding a portion of the tubular member and extending toward the distal tip of the tubular member and an optical fiber extending along a length of the flat surface between the tubular member and the sheath member. The instrument may further include a slack chamber, collar structure, and fiber guard member to support and guide the optical fiber to the distal tip.

Abstract: Improved optical fiber coupling reliability is realized by improving structures and materials used at the fiber joint. When ceramic ferrules are used at the fiber joint, the penetration of a UV-cured optical adhesive between the ceramic ferrules and the fiber ends is avoided or prevented, while an anti-reflective coating, an uncured optical adhesive, or a refractive index matching gel may be applied between the ceramic ferrules. When glass ferrules are used at the fiber joint, the UV-cured optical adhesive may be applied and fully cured between the glass ferrules and the fiber ends.

Abstract: La presente divulgación se refiere a un cable de fibra óptica multinúcleo (MCF). En algunas realizaciones, un MCF comprende una pluralidad de núcleos, un revestimiento que rodea la pluralidad de núcleos, en el que el índice de refracción de uno o más de la pluralidad de núcleos es mayor que el índice de refracción del revestimiento, y un revestimiento que rodea el revestimiento. un extremo distal libre del recubrimiento y que tiene un diámetro reducido. El MCF también comprende un espacio anular formado entre el extremo distal del MCF y la superficie interior de la cánula, en el que se mantiene la concentricidad del extremo distal del MCF con el paso interior de la cánula.

Abstract: Un conjunto de cánula oftálmica puede incluir una cánula que tiene una superficie de cánula exterior y un orificio cilíndrico interno. Un cubo contiguo a un extremo proximal de la cánula puede definir un diámetro de cubo externo máximo que es mayor que un diámetro exterior de la cánula. Se puede unir una fibra óptica a la superficie de la cánula exterior durante al menos una porción de una longitud de la cánula. Un material de cubierta puede estar en contacto con la superficie de la cánula externa y puede cubrir al menos una porción de la fibra óptica. Un difusor de luz se puede eliminar en una punta distal de la fibra óptica. (Traducción automática con Google Translate, sin valor legal)

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.
