Abstract:

A process for forming a metallic tubular connector of the type having a cylindrical shell which extends circumferentially about a tubular body for joining said tubular connector to a conduit. The process involves using a first forming machine to form a first peripheral bead in a first end portion of a tubular metallic body, having a substantially uniform diameter and wall thickness, reduce the outside diameter of a second end portion, and slope an intermediate surface portion. Then, a second end forming machine tool, carrying a metallic socket, freely receives the tubular body second end portion, contacts the sloped intermediate surface portion, forms a second peripheral bead adjacent the first peripheral bead, while an annular end surface of the socket is compressed and locked between the first and second beads. Further, the tubular body is manufactured from a 5000 series aluminum alloy material.

US Classification:

606261, 606254

Abstract:

A method of manufacturing a curved spinal rod is disclosed. The method includes heating PEEK; injecting the PEEK into an arcuate spinal rod mold; holding the injected PEEK in the mold until the PEEK substantially sets; and removing the injected PEEK from the mold. In another aspect, a spinal rod is disclosed. The spinal rod includes an arcuate main body having a first end portion, a second end portion, and a central portion. The central portion has a non-circular cross-section with a height greater than its width. The first and second end portions and the central portion of the arcuate main body are integrally formed of a polymer such as polyetheretherketone (PEEK). The spinal rod also includes a rounded end cap adapted to mate with at least one of the end portions. The end cap is radiopaque.

Abstract:

Spinal support members having varying stiffnesses are disclosed. In one embodiment, an elongated spinal prosthetic includes a pair of curved elongated portions. The portions are formed of materials having different stiffness characteristics such that the stiffness of the prosthetic varies along its length. In another embodiment, an elongated spinal implant includes a pair of threadedly engaged elongated sections. The first section is formed of a first material having a first rigidity. The second section has an inner portion formed of the first material and an outer portion formed of a second material. The second material is less rigid than the first material. In another embodiment, a modular spinal rod is provided. The modular spinal rod includes a pair of connectable rod portions with different stiffness characteristics. In yet another embodiment, a kit for a modular spinal rod includes a plurality of connectable modular rod portions having different stiffness characteristics.

US Classification:

623 1716, 623 1711, 606246

Abstract:

An interspinous spacer system includes a core configured to fit between adjacent spinous processes, a first fork movable relative to the core from a non-use position to an in-use position, and second fork. When in the in-use position, the first fork extends outwardly from a first side of the core and bounds an opening. The second fork extends outwardly from a second side of the core, opposite the first side, and bounds the opening. Third and fourth forks extend outwardly from the first and second sides of the core respectively and form a second opening. The second, third, and fourth forks are affixed relative to the core and relative to each other. The first fork is inserted between spinous processes in the non-use position to avoid damage to a superspinous ligament adjacent the spinous processes. Other aspects and related methods are also disclosed.

US Classification:

606270

Abstract:

A locking device and method are provided for a bone stabilization system which includes a bone anchor, a coupling mechanism and a stabilization member, wherein the coupling mechanism couples the stabilization member to the bone anchor. The locking device includes a seating member and a posted member. The seating member is operatively associated with the coupling mechanism for securing the stabilization member within the coupling mechanism, and is configured with an opening therein. The posted member, which includes an interface member and a post extending therefrom, is configured for disposition between the seating member and the stabilization member with the post extending therefrom being received into the opening in the seating member when the seating member is employed to secure the stabilization member within the coupling mechanism. The post is sized to engage and facilitate control of the stabilization member as the seating member operatively engages the coupling mechanism.

US Classification:

623 1716, 606248

Abstract:

The present application is directed to devices and methods for spacing and/or positioning spinous processes of vertebral members. The device may include a first wing to position on a first lateral side of spinous processes and a second wing to position on a second lateral side of spinous processes. An intermediate member extends between the wings and fits within the interspinous space. The device may be selectively adjustable from a first orientation with the second wing received by the intermediate member. This first orientation may include a reduced sized to facilitate insertion of the device with a lateral approach into the interspinous space. The device may also be moved to a second orientation with the wing deployed from the intermediate member. The second orientation may provide for the second wing to be positioned on the second side of the spinous process opposite from the first wing. The intermediate member may be positioned within the interspinous space to retain a predetermined distraction height.

Abstract:

The present application is directed to set screws used with fasteners to capture and engage an elongated member. The set screws include a body sized to attach to a receiver of the fastener. A deformable member may be attached to an end of the set screw and provides for the set screw to more fully engage the elongated member to prevent potential damage to the elongated member and prevent the set screw from backing out of the fastener. In one embodiment, just the deformable member contacts the elongated member. In another embodiment, the deformable member and the body contact the elongated member. In yet another embodiment, a contact member is attached to the deformable member to contact against the elongated member.
