  • Patent number: 9987052
    Abstract: A modular interspinous system is shown having a first plate, a generally opposing second plate and a modular insert that may be removably or permanently secured to the first plate. The first plate has a coupling means, coupler or connection system in the form of a screw that may be permanently or non-permanently docked or supported in the first plate. The modular insert is adapted, sized and shaped to expose at least a portion of the screw thread of the screw and that portion may cooperate with at least one mating female thread in the second plate, thereby enabling a user to rotate the screw in order to drive the first and second plates towards or away from each other and, for example, into compression with bone.

  • Publication number: 20170095281
    Abstract: A plate system and method comprising a plate and a screw having an integral resilient lock. The screw comprises a head that has a portion that is adapted to be compressible as it is screwed into bone using a tool. After the screw head is received in the plate and the tool is removed therefrom, the screw head decompresses or expands into a locking or receiving area, thereby locking the screw in the plate. The plate is adapted to have at least one or a plurality of detents or lips for cooperating with at least a portion of the screw head to retain the screw in the plate and prevent it from withdrawing therefrom.

  • Patent number: 9439689
    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.

  • Patent number: 9265540
    Abstract: A system comprising a screw element having a generally cylindrical body having a bore or lumen therethrough and a plurality of fenestrations or windows through which biological material may be provided. The system comprises a tool for inserting the biological material into the screw element so that the biological material may extrude through the plurality of fenestrations or windows and through an aperture in the tip of the screw element thereby enabling providing a fusion mass across two adjacent facet bones or a facet joint wherein the screw itself provides both a fixation component and a screw component.

  • Patent number: 9078706
    Abstract: A system and method includes a housing dimensioned to be situated between adjacent spinal bones, such as adjacent vertebrae. Screws are provided in one embodiment and are dimensioned or configured to lock against each other to retain the screws and, consequently, the cover in place. Another embodiment illustrates a plurality of plate elements that can be slidably received and locked in the cage. Each of the plate elements are adapted to receive at least one screw and guide the screw at a predetermined angle into a vertebra, thereby securing the cage in an inter-vertebral space.

  • Patent number: 8998906
    Abstract: A surgical implant inserter compressor is shown having a plurality of jaws and is adapted to permit at least one or both jaws to move generally parallel with respect to each other or move along an axis wherein the jaws remain in a plane that is generally perpendicular to that axis. The surgical implant inserter compressor is adapted for implanting at least one or a plurality of plates onto a pair of spinous processes and is adapted to distribute the clamping force with which the implants engage the spinous processes. The surgical implant inserter compressor may be adapted to permit one or both jaws to float or pivot to accommodate different anatomical structures, such as spinous processes that are not aligned, are of different sizes or shape and the like. An optional tool guide for guiding a tool to drive a lock to lock the plates together is also shown.
