    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 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: 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.

    Abstract: Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.
