  • Publication number: 20160058563
    Abstract: A method of implanting an intervertebral spacer may include positioning the intervertebral spacer within an intervertebral space defined by adjacent vertebral bodies. The intervertebral spacer may include a plurality of bores, and each of the plurality of bores may be configured to receive either a linear fastening element or a curvilinear fastening element. The method also may include selecting a first fastening element from a group including linear fastening elements and curvilinear fastening elements, and inserting the first fastening element into a first bore of the plurality of bores such that the first fastening element is inserted into one of the adjacent vertebral bodies to secure the intervertebral spacer within the intervertebral space.

  • Publication number: 20150044013
    Abstract: A magnetic retrieval tool for retrieving devices, such as probes, from a pressurized system. The retrieval tool uses a magnetic coupling to transfer movement of an external mechanism (i.e. external to the pressurized system), such as by an operator's manual movement, a motor or other drive, to an internal mechanism (i.e. internal to the pressurized system). The magnetic coupling may be through a wall of a pressure vessel using an outer magnetic core coupled to the outside of the pressure vessel which magnetically couples to an inner magnetic core disposed on the inside of the pressure vessel, such that translational or rotational movement of the outer magnetic core cause substantially simultaneous and corresponding translational and/or rotational movement of the inner magnetic core. An end effector tool is coupled to the inner magnetic core to engage and retrieve or insert the device into the pressurized system.

  • Publication number: 20140348283
    Abstract: Application of axial seed magnetic fields in the range 20-100 T that compress to greater than 10,000 T (100 MG) under typical NIF implosion conditions may significantly relax the conditions required for ignition and propagating burn in NIF ignition targets that are degraded by hydrodynamic instabilities. Such magnetic fields can: (a) permit the recovery of ignition, or at least significant alpha particle heating, in submarginal NIF targets that would otherwise fail because of adverse hydrodynamic instability growth, (b) permit the attainment of ignition in conventional cryogenic layered solid-DT targets redesigned to operate under reduced drive conditions, (c) permit the attainment of volumetric ignition in simpler, room-temperature single-shell DT gas capsules, and (d) ameliorate adverse hohlraum plasma conditions during laser drive and capsule compression. In general, an applied magnetic field should always improve the ignition condition for any NIF ignition target design.

  • Publication number: 20140257401
    Abstract: The present application generally relates to orthopedic stabilization systems, and in particular, to systems including clamps. The clamps can be used in addition to or to replace hooks that grasp onto bone members, such as the lamina. One example of such a clamp is an in-line clamp that includes a central opening for receiving a rod member, a first opening for receiving a set screw and a second opening for receiving an elastic member therethrough. Another example of such a clamp is an off-set clamp that includes an upper plate, a bottom plate, and an opening for receiving a rod therein. The upper plate can be separated from the bottom plate to make space for an elastic member that can be secured within the plates. Tulip clamps that utilize one or more elastic members are also provided.

  • Patent number: 8810264
    Abstract: A method of sensing corrosion of a pipe covered by a layer of insulation comprises positioning a CUI sensor radially adjacent an outer surface of the pipe. The CUI sensor comprises a non-conductive base having a first end and a second end opposite the first end. In addition, the CUI sensor comprises a first test circuit mounted to the base. The first test circuit includes a first conductor, a second conductor, and a first testing element extending between the first conductor and the second conductor. Further, the method comprises exposing the first testing element to the same environment as the outer surface of the pipe. Still further, the method comprises determining whether the first testing element has corroded through. Moreover, the method comprises assessing whether corrosion of the pipe has occurred based on the determination of whether the first testing element has corroded through.
