摘要:
A delivery device for inserting an interbody implant into an intervertebral space in a patient has an elongate tube with a channel and is sized to fit in an intervertebral space. The elongate tube has a proximal portion, a distal portion, a longitudinal axis, and a window with a longitudinal axis. The window is disposed adjacent the distal portion of the elongate tube and the longitudinal axis of the window is offset from the longitudinal axis of the elongate tube. The channel is sized to receive the interbody implant, and also the channel is configured such that the interbody implant is advanced therealong from the proximal region toward the distal region. The interbody implant is deployed into the intervertebral space from the window.

A delivery instrument for placing an interbody implant into an intervertebral space of a patient comprises a plurality of elongated plates disposed adjacent one another. Each elongated plate has a proximal portion and a distal portion. The distal portion is sized and shaped to fit into the intervertebral space, and is configured to engage a vertebral body in the intervertebral space. An expandable member is coupled to the plurality of elongated plates so as to form an enclosed tube that is sized and shaped to receive the interbody implant. The expandable member allows for translation of the plurality of elongated plates relative to one another as the interbody implant passes through the tube.

Methods and apparatus for providing correction of one or more maladies or conditions of the spinal column of a living being. In one embodiment, the apparatus includes an implant delivery instrument and an implant for use therewith. In one variant, the implant delivery instrument includes a non-detachable distraction member for distraction of the disc space and a track for slidable delivery of an implant to the distracted disc space. In another variant, the implant delivery instrument includes a detachable distraction member for distraction of the disc space and a track for slidable delivery of an implant to the distracted disc space. In the latter variant, the distraction member is co-implanted in the disc space with the implant.

摘要:
An apparatus for drying a wetsuit (‘Dryer Cup’) is composed of an elongate member and a fluid receptacle. The dryer cup is configured such that the retained water in the wetsuit drains into the fluid receptacle. This allows the user to dry the wetsuit indoors without dripping water on the floor. The elongate member keeps the sleeves of the wetsuit open for air exchange. This improves dry time of the wetsuit, and allows for the option to introduce a fan or other method to improve air flow through the wetsuit garment.

An improved method of operating an arc furnace is provided. The sidewall of the furnace includes a refractory lining. A charge of scrap metal is added to the furnace. The charge is melted and a slag layer is formed on the top of the melting charge. The furnace is tapped at the bottom to remove a portion of the melted charge. After tapping the furnace, the slag is splashed onto the sidewall to thereby coat the sidewall with a frozen slag layer.

Techniques to explain authorization origins for protected objects in an object domain are disclosed. In one embodiment, for example, an apparatus may comprise a processor circuit, a request processor component operative on the processor circuit to receive and process a request for an authorization origin of a resource object, the authorization origin comprising an access control with a permission arranged to control access to the resource object based on an identity, and a resource origin component operative on the processor circuit to identify the authorization origin of the resource object from a set of interrelated resource objects and associated access controls, retrieve authorization origin information for the authorization origin, and present the authorization origin information in a user interface view. Other embodiments are described and claimed.
摘要:
A graphite electrode exhibits oxidation resistance by modifying the outer radial surface characteristics. The outer radial surface may be modified by providing a textured portion which improves water flow while minimizing water absorbtion. Alternately, a layer of flexible graphite or plurality of particles of exfoliated graphite may be disposed on the outer radial surface of the electrode body.

A metal delivery apparatus for casting metal strip includes at least one elongated segment having a main portion extending longitudinally through the main portion with end walls at opposite ends thereof, the main portion communicating with outlets along opposite sides of each segment adapted to upwardly discharge flow of molten metal into a casting pool.
摘要:
An electrode joint is presented, the joint including two joined graphite electrodes having blocked threads and having a locking ring interposed between the electrodes, the locking ring composed of a material having a coefficient of friction such that the tendency of the electrode joint to unscrew is retarded.
