Abstract: A GPS unit may be linked to an illumination devise so as to provide a seamless indication of directional movement in comparison to a desired course. The orienteering tool may have input means so as to program in a desired course, including keys, touch screen, or an external input connected through other means such as a USB port. A memory may be connected to a processor and may contain basic cartographic data or more. Other useful tools may be integrated into the tool for further increased utility.

Abstract: A method of manufacturing an optical probe for use in ophthalmic procedures can comprise: positioning a ferrule within a proximal portion of a cannula, wherein an optical fiber extends at least partially through the ferrule towards an optical element disposed within a distal portion of the cannula; and coupling the cannula to the ferrule by applying laser energy to the cannula. An optical probe can be provided that includes a cannula including a proximal portion and a distal portion; a ferrule disposed within the proximal portion of the cannula, the cannula and the ferrule coupled together by engaged deformations in the cannula and the ferrule; and an optical fiber positioned at least partially within the optical probe, the optical fiber configured to receive a light from a light source and guide the light to an optical element positioned within the distal portion of the cannula.

Abstract: A valve assembly having a threadless base and a removable threadless insert that separately contains a check valve piece. The check valve piece is resiliently supported to abut a seal fitted to the insert. In one assembly, a pair of resiliently biased latch arms restrain the insert to the base. Flanges at the latch arms are resiliently biased to flex and grip the base as the insert is pushed into the base. Insert removal is effected with the release and lifting of the latch arms. In another assembly, the insert is magnetically coupled to the base and a resiliently biased check valve piece and setscrew adjuster regulates flow pressure.

Abstract: A valve assembly having a base and a removable latched insert that separately contains a valve piece. The valve piece is resiliently supported to abut a seal fitted to the insert. The insert is restrained to the base with a pair of resiliently biased latch arms that radiate from the insert. Flanges at the latch arms are resiliently biased to flex and grip the base as the insert is pushed into the base. Insert removal is effected with the release of the latch arms and a lifting of the latch arms.
