  • Patent number: 7931674
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the distraction guide can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

  • Patent number: 7909853
    Abstract: Systems in accordance with embodiments of the present invention can include an implant comprising a spacer for defining a minimum space between adjacent spinous processes, a distraction guide for piercing and distracting an interspinous ligament during implantation, and a binder for limiting or preventing flexion motion of the targeted motion segment. The binder can be secured to a brace associated with the implant during implantation by a capture device. In one embodiment, the capture device includes a fixed piece extending from the brace and a slidable piece associated with the fixed piece. A fastener can be rotated to pinch the binder between the slidable piece and a wall of the brace, securing the binder. A physician need not know the length of the binder prior to implantation, reducing the time required to perform a procedure.

  • Patent number: 7837734
    Abstract: A system and method for replacing degenerated spinal disks in accordance with the present invention can substitute for interbody fusion techniques by replacing degenerated spinal disks with artificial spinal disks. In one embodiment, the system can comprise one or more artificial spinal disks, each comprising an upper and lower housing, a first spacer and a second spacer partially enclosed by a cavity formed by the housings, and a shaft with a spring positioned between the first spacer and the second spacer such that the spacers are urged apart.

  • Publication number: 20100262243
    Abstract: A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. The implant provides a spinal extension stop while allowing freedom of spinal flexion. An interspinous process implant with a selectably expandable spacer can be placed between adjacent spinous processes. a device implanted between the spinous processes of adjacent vertebrae of the spine can be used for relieving pain associated with the vertebrae and surrounding tissues and structures by maintaining and/or adding distraction between adjacent vertebrae. A tissue expander can be adapted to move from a first insertion position, for ease of implantation between spinous processes, to a second retention position that prevents displacement of the implant.

  • Publication number: 20080046086
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.
