  • Patent number: 10271878
    Abstract: A spinal cross-connector for connection between adjacent first and second rods and method for use of the same are disclosed. In one embodiment, a coupling member including a bar extends from a body portion opposite to and in longitudinal axial alignment with a c-shaped arm. A second coupling member which includes a rack extends from a body portion opposite to and in longitudinal axial alignment with a another c-shaped arm. The rack is superposed in a selectively adjustable overlapping mechanical engagement with the bearing surface. Each c-shaped arm includes an arcuate extension extending substantially parallel to the bar to define a gripping pocket. A set screw includes a conical profile that extends substantially perpendicular to the arcuate extension. The advance of the set screw is operable to urge the rod into pressing contact with the gripping pocket to secure the rod therein.

  • Patent number: 10034693
    Abstract: A spinous laminar clamp system is disclosed herein. The preferred embodiments are either a three or a four-point fixation system at a particular vertebral level. For example, a two-point adjustable fixation below a vertebrae and a single-point non-adjustable point above the vertebrae exemplifies the three-point fixation. Multiple level and further stabilizing is provided by fixation to subjacent vertebrae above and/or below with a connecting rod providing unitization between levels. Specific designs are applicable to the cervical spine; however, fixation at all levels and regions of the human spine are contemplated.

  • Patent number: 8083780
    Abstract: A mechanism for fixing a spinal support to vertebrae includes a support member and a pedicle screw component. The support member comprises an elongated end comprising a longitudinal axis. A hook connects to the elongated end and receives the vertebrae. The hook is angled in three different planes with respect to the longitudinal axis. A connector section connects the elongated end to the hook and is angled with respect to the elongated end and comprises a thickness less than a thickness of the elongated end. The pedicle screw component comprises a fixation component anchored in the vertebrae. The fixation component comprises a socket; a screw head comprising a bulbous end that fits into the socket; and a channel that receives the elongated end. A pin causes outward expansion of the bulbous end; and a blocking mechanism is attached to the screw head and adjacent to the elongated end.

  • Patent number: 8029505
    Abstract: An external fixation system for connecting one or more bone segments together to facilitate healing of bone. The system may include one or more rings and/or ring segments. One or more linear distractors and/or angular distractors may connect the rings to each other so as to allow for distraction and/or reduction/compression of a bone. Linear distractors may enable an operator to move the rings towards and away from each other, while angular distractors may enable an operator to angle the rings relative to each other. In an embodiment using angular distractors, one or more angular separation assemblies may be positioned between the rings. These separation assemblies may have joints which may two portions which may be angled relative to each other and connected directly or indirectly to the rings. Various fasteners (e.g., nuts) and/or tightening members may configured for quick movement along and selective tightening to various components.

  • Patent number: 8021399
    Abstract: A rod extension for extending a fusion construct allows a surgeon to connect a stabilization rod implant to at least a portion of a patient's spine, and also to connect the stabilization rod implant to an existing implant that has been previously installed in the patient. The existing fusion implant typically includes at least one existing pedicle screw, at least one existing rod, and at least one existing connector interconnecting the existing pedicle screw to the existing rod. The extension implant comprises a rod, an offset beam connected to the rod, and a clamp interconnected to the offset beam, wherein the clamp can be secured to the existing rod, thereby extending the fusion construct.

  • Patent number: 7942906
    Abstract: The present invention includes a system and method for the stabilization and fixation of the lumbar spine. Another aspect of the invention includes a system and method for the stabilization and fixation of the lumbar spine in a minimally invasive manner. The system can include a plurality of pedicle screws, a support rod, a plurality of rod clamps, and a plurality of coupling members. In one aspect, each coupling member can be configured to engage a proximal portion of a pedicle screw and can have a socket portion that is configured to receive a socket engaging portion of the rod clamp, such that the coupling member and the pedicle screw can be pivoted three-dimensionally relative to the rod clamp and the support rod.

  • Patent number: 7927357
    Abstract: A method and apparatus for providing an adjustable length surgical implant is provided, wherein the surgical implant is readily adjustable by a surgeon using a surgical tool sized for use with the surgical implant. Adjustment of the surgical implant further requires a small incision through the skin prior to the adjustment of the length of the implant, such that the potential for infection is greatly reduces and the associated trauma of surgery is lessened for the patient.

  • Patent number: 7918876
    Abstract: An adjustable spinal implant (10) is provided for use in connecting elongate members (12) as well as vertebral spacers such as corpectomy devices, intervertebral fusion devices, and other prostheses. The implant (10) may have fittings (80) on either end comprising fixed (100) or articulating (200) jaws, endplates, or other engagement structures. The implant (10) comprises a housing (40) with an internal rotor (60); an extending shaft (20); and a locking collar (70). The extending shaft (20) has an external helical groove (23) that meshes with an internal helical groove (63) on rotor (20). Length adjustment occurs by transforming axial movement of the extending shaft (20) into a rotary movement of the rotor (60) via helical engagement. The locking collar (70) comprises protrusion (73) engaging grooves (63) of rotor (60), thus providing a simple, positive locking mechanism without requiring the surgeon to apply excessive force to lock the length.
