    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: A pneumatic valve directs pressurized air to and air exhaust from a surgical implement, such as a dual actuation vitreous probe. The pneumatic valve includes an axially symmetric valve body configured to rotate from a first position, in which the pneumatic valve places a first port of the surgical implement in fluid communication with the pressurized air and a second port of the surgical implement in fluid communication with the air exhaust, to a second position, in which the pneumatic valve places the first port in fluid communication with the air exhaust and the second port in fluid communication with the pressurized air, and back to the first position, in one rotational direction. As such, the axially symmetric valve body continuously rotates in one rotational direction to alternate the pressurized air and the air exhaust between the two ports of the surgical implement to drive the dual actuation operation.

    Abstract: A beam delivery system for a probe includes a plurality of laser sources configured to generate a respective incident beam, including a first laser source generating a first incident beam and a second laser source generating a second incident beam. The system includes routing structures respectively positioned along a path of the respective incident beam. An optical subsystem is adapted to sequentially direct a respective output beam from the routing structures into each core of a multi-core fiber in communication with the probe. The first routing structure and the second routing structure respectively include an array of optical elements adapted to be synchronously moved such that the first incident beam and the second incident beam encounter an identical member of the array at a same time.

    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.
