Abstract: An optical surgical probe includes a handpiece having a metal cannula at a distal end, a light guide within the metal cannula that carries a light beam from a light source through the metal cannula, and a multi-spot generator formed within a distal opening of the metal cannula that seals the distal opening of the metal cannula. The multi-spot generator includes a proximally-facing faceted end surface spaced from a distal end of the light guide that includes at least one facet oblique to a path of the light beam and a ball lens located distal to the faceted end surface. A high-conductivity ferrule surrounds the distal end of the light guide, is in thermal contact with the metal cannula, and includes a side-shield portion extending beyond the distal end of the light guide. The ferrule shields the cannula from a portion of the light beam reflected by the faceted end surface.

Abstract: Certain embodiments of an endoilluminator may include a cannula, an intermediate material, and an optical fiber. The cannula has a substantially cylindrical shape that defines an interior region and has a cylindrical axis. The intermediate material is disposed within the interior region. The optical fiber is disposed within the intermediate material and has a fiber optical axis and a distal end configured to emit light. The emitted light has an illumination pattern with an illumination axis that is not parallel to the cylindrical axis.

Abstract: A surgical probe includes a cannula assembly, having a graded index (GRIN) fiber that is configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end; an adapter, having a distal end, configured to receive the cannula assembly, with the proximal end of the GRIN fiber, a proximal end, configured to couple to a light guide via a connector and to receive a light delivered by the light guide from a laser source to the adapter, and an interface, configured to couple the light delivered by the light guide to the proximal end of the GRIN fiber; wherein a length of the GRIN fiber is sufficiently long that the interface is outside a patient's eye during a photocoagulation procedure.
