  • Patent number: 10188434
    Abstract: This invention relates to an improved structure for an interspinous stabilization device that more evenly distributes loads throughout the adjacent vertebrae than known interspinous stabilization devices, and further readily compensates for graft settling so as to maintain continued axial loading of the graft. More specifically, this invention relates to a medical device that helps in performing a spinal fusion procedure by holding the bone graft in place and stabilizing the facet screw by a plate that is attached to it. The invention also performs a dynamic function that compensates for settling of the bone graft over time. This dynamic function may, if desired, be enhanced by a movement-limiting mechanism that allows extension but not flexion such that the bone graft fusion remains in contact and fusion takes place.

  • Patent number: 9138263
    Abstract: An improved flexible component used for dynamic stabilization of spinal segments for the treatment of vertebrae deformities and injuries and for the replacement of a complete or segment of the body of a vertebra in the spine is described. The flexible component is comprised of a solid, suitable implant material with a longitudinal bore the entire length and an appropriately formed slot which extends spirally around the shaft either continuously or segmentally. The flexible component may be encapsulated, fully or partially, in a suitable implant grade elastomeric resilient material. When used for a dynamic stabilization device, the component is attached to the vertebral bodies by pedicle screws know to those in the art. When used as a vertebral replacement device, attached to the component's opposite ends are members for attachment to the adjacent vertebra that allow for height and angular adjustment.

    Abstract: Systems and methods for stabilizing or adjusting the position of at least one spinal motion segment, such as a posterior element distraction system. The system includes an implantable member having at least one of a lateral member and a transverse member. The lateral member may be expandable in at least one dimension, for example, in a direction along the axis of the spine. The expandable member may be an inflatable balloon, expandable scaffolding, strut, or combination thereof and may provide stability and anchoring to the implantable member.

  • Patent number: 9017388
    Abstract: The present application is directed to devices and methods for correcting a spinal deformity. A spacer is positioned between processes that extend outward from a pair of vertebral members. A force applicator is operatively connected to apply a force to the vertebral members. The spacer then acts as a fulcrum with the force causing the vertebral members to pivot about the spacer and become aligned in a more desired orientation to eliminate or reduce the deformity.

  • Patent number: 8979899
    Abstract: The invention concerns a distance-keeping inter-process implant with a body ending in its posterior part with two opposite-situated resistance protrusions. In the anterior part of the body there are situated at least two wings, at least one of which is a mobile wing connected with the body by an articulated joint. Each wing is provided with at least one guide of the tensioning band. The articulated joint between the mobile wing and the body is formed by the mutually collaborating shaped surface of the. wing (and the shaped surface of the body and is usefully secured by the pin that constitutes the axis of rotation of the mobile wing. In an alternative version of the implementation of the implant, the mobile wing connected with the body is provided with at least one arm situated with respect to the wing at the angle ? amounting to from 30° to 150°.

  • Patent number: 8932333
    Abstract: A modular interspinous fixation system and method are shown. The system and method comprise a first plate, a second plate and a locking cross bar for locking the first and second plates together and into locked engagement with a first spinous process and a second spinous process. A bridge is mounted or received on the locking cross bar so that it becomes locked onto the locking cross bar when the locking cross bar is in locked engagement. The bridge and locking cross bar are adapted so that the bridge does not rotate about its axis while on the locking cross bar. Various other embodiments are shown illustrating various bridges of different shapes and sizes, integral and non-integral locking cross bars and even a ramped locking cross bar for facilitating preventing separation of the first and second plates after they are mounted to the first and second spinous processes.
