    Abstract: In certain embodiments, an illuminating endoprobe system includes one or more light sources, a housing, a vitreous visualization fiber, and a general illumination fiber. The light sources generate a visualization light and an illumination light. The housing receives the visualization and illumination light, and has a probe tip with a probe axis. The vitreous visualization fiber transmits the visualization light through the probe tip. The visualization light has a visualization axis and a visualization beam angle at the probe tip. The general illumination fiber transmits the illumination light through the probe tip. The illumination light has an illumination axis and an illumination beam angle at the probe tip. The illumination beam angle is greater than the visualization beam angle, and the illumination axis is at an offset angle relative to the visualization axis, where the offset angle greater than 5 degrees.

    Abstract: Certain embodiments disclosed herein provide systems and devices for coupling optical fibers with laser surgical systems. In particular, certain aspects provide a push-pull connector and adapter for releasably coupling an optical fiber with a port of a laser surgical system. The connector and adapter facilitate mechanical lateral and rotational guidance of the optical fiber during insertion into the port to ensure proper alignment (e.g., clocking) of the optical fiber’s cores with a laser beam pattern propagated by the laser surgical system. Accordingly, the connector and adaptor enable improved coupling efficiency between the laser beam pattern and one or more cores of the optical fiber, and therefore improved power uniformity between multiple laser beams transmitted through the cores.

    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: An illuminated microsurgical instrument comprises a distally projecting tubular member arranged to perform a medical procedure at an interventional site, a sheath member surrounding a portion of the tubular member, and an optical fiber extending along a length of the outer surface of the tubular member between the tubular member and the sheath member. A method of manufacturing an illuminated microsurgical instrument comprises placing an optical fiber on a positioning member, placing a sheath member around the optical fiber and positioning member and securing the sheath member to the optical fiber, removing material from a distal end of the sheath member and optical fiber at a non-perpendicular angle with respect to a longitudinal axis of the positioning member, removing the positioning member from within the sheath member, and placing the sheath member with the optical fiber secured thereto around a distally projecting tubular member.

    Abstract: The present disclosure relates to a fiber and a laser probe assembly with a probe tip that houses the fiber. In certain aspects, the fiber includes a core, an outer cladding surrounding the core, and an end face at a proximal and/or distal end of the fiber. The core is configured to transmit a laser light beam while the core and the outer cladding are both configured to transmit an illumination light. In certain aspects, a surface area of the end face corresponding to a cross-section of at least the outer cladding is treated with a roughening or polishing process to modulate an illumination light output angle of the fiber. Using a fiber that is configured to transmit a laser light beam as well as a wide-angle illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.

    Abstract: The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.
