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.

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 and an outer cladding surrounding the core. 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. Using a fiber that is configured to transmit a laser light beam as well as an illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.

Abstract: Devices and methods are disclosed for an optical component mounting system for supporting an optical component such as a laser. The mounting system comprises a first component comprising a first surface, a second component comprising a second surface facing the first surface, and adhesive between the first surface of the first component and the second surface of the second component, wherein the first component comprises at least three mounting pads extending from the first surface for contacting the second surface of the second component and providing direct support between the first component and the second component. The component comprising the mounting pads may be a lower mount, an upper mount such as an upper clamping mount, or a bonding pad or other component in the stack of components. A method of assembling the stack of components may comprise curing the adhesive at a temperature at or above an upper end of an expected temperature operating range for the optical component mounting system.

Abstract: An example illuminated microsurgical instrument comprises a handpiece, a tubular member connected to the handpiece to perform a medical procedure at an interventional site, a sheath member surrounding a portion of the tubular member and extending toward the distal tip of the tubular member, and an optical fiber positioned within the sheath member and connected to the sheath member, wherein a distal tip of the optical fiber is recessed within the sheath member and directed toward the distal tip of the tubular member. The sheath member and distal tip of the optical fiber may be movable between a proximal position at a first distance from the distal tip of the tubular member and a distal position at a second distance from the distal tip of the tubular member, wherein the second distance is shorter than the first distance. Movement of the sheath member moves the distal tip of the optical fiber to generate a wider illumination or a narrower illumination on the site being visualized.
