Abstract: Various embodiments are generally directed to a surgical probe with shape-memory material, such as a probe with a set of light sources, for instance. Some embodiments are particularly directed to a cannula with a shape-memory material that is used to secure a window. In one or more embodiments, for example, an apparatus for surgical use may include a cannula with a shape-memory material in an austenitic phase. In some embodiments, the window may be positioned at an opening of the cannula when the shape-memory material is in a martensitic phase. In some embodiments, transitioning the shape-memory material from the martensitic phase to the austenitic phase secures the window in position at the opening of the cannula.

Abstract: Certain aspects of the present disclosure provide a thermally robust laser probe assembly comprising a cannula, wherein one or more optical fibers extend at least partially through the cannula for transmitting laser light from a laser source to a target location. The probe assembly further comprises a lens housed in the cannula and a protective component press-fitted to the distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component.

Abstract: A laser probe includes a cannula, at least one optical fiber positioned within the cannula, and a lens positioned within the cannula at a distal end of the fiber. The lens is adapted to receive a laser beam from the optical fiber at a proximal end of the lens and to transmit the laser beam towards a distal end of the lens. The laser probe includes an optical element configured coupled to the cannula by a brazed joint and to receive the laser beam from the distal end of the lens and emit the laser beam from the probe. The brazed joint may form a hermetic or liquid-tight seal between the optical element and the cannula.
