    Abstract: Un método y sistema proporcionan un dispositivo de infusión quirúrgica que incluye una cánula y una fibra óptica acoplada a la cánula. La cánula tiene un canal que la atraviesa y un diámetro exterior. El canal tiene un diámetro interior menor que el diámetro exterior. La fibra óptica está acoplada a la cánula. Al menos una parte de la fibra óptica acoplada a la cánula tiene un diámetro no superior a la mitad del diámetro interior. (Traducción automática con Google Translate, sin valor legal)

    Abstract: Particular embodiments disclosed herein provide a surgical laser system comprising first laser source configured to emit a first laser beam with a first wavelength and a second laser source configured to emit a second laser beam with a second wavelength. The surgical laser system further comprises a first diffraction optical element (DOE) tuned to the first wavelength and a second DOE tuned to the second wavelength, wherein the first DOE is configured to diffract the first laser beam into one or more first diffracted beams at a diffraction angle and the second DOE is configured to diffract the second laser beam into one or more second diffracted beams at the same diffraction angle. The surgical laser system further comprises one or more beam splitters configured to reflect the one or more first diffracted beams and the one or more second diffracted beams onto a lens.

    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: A surgical probe system comprising a surgical probe having a probe needle, an optical fiber incorporated onto the probe needle, wherein a proximal end of the optical fiber is connected to a light source and a distal end of the optical fiber projects illumination light from the light source over a tip of the probe needle; and an adjustment mechanism that varies the illumination light between a first beam having a first numerical aperture that facilitates vitreous visualization and a second beam having a second numerical aperture that facilitates background illumination, wherein the second numerical aperture is larger than the first numerical aperture.

    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.
