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

Abstract: A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

Abstract: An ophthalmic cannula assembly may include a cannula having an outer cannula surface and an inner cylindrical bore. A hub adjoining a proximal end of the cannula may define a maximum outer hub diameter that is greater than an outer diameter of the cannula. An optical fiber may be attached to the outer cannula surface for at least a portion of a length of the cannula. A cover material may be in contact with the outer cannula surface, and may cover at least a portion of the optical fiber. A light diffuser may be disposed at a distal tip of the optical fiber.

Abstract: An illumination fiber optics is provided that includes an optical fiber, configured to receive illumination light at a proximal end from a light source; and a light-scattering element, at a distal end of the optical fiber, configured to receive the illumination light from the optical fiber at a proximal end and to emit the illumination light at a distal end in a wide angle. The illumination fiber optics can be prepared by providing an optical fiber, configured to receive illumination light at a proximal end from a light source; and creating a light-scattering element at a distal end of the optical fiber, configured to receive the illumination light from the optical fiber at a proximal end and to emit the illumination light at a distal end in a wide angle.

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: In some embodiments, an illuminated microsurgical instrument system includes a microsurgical instrument having a distally projecting tubular member arranged to perform a medical procedure. 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 include an opening such as a slot in the distal end of the sheath member to direct exiting air away from the tip of the optical fiber. 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.
