  • Publication number: 20140358186
    Abstract: An insertion device for deploying an implant includes an elongated main body having a distal locking portion for coupling to the implant and a proximal handle portion. The main body defines a central passage and the distal locking portion has outer ridges and slots to allow the outer ridges to flex radially inward when mounting to the implant. A plunger slides in the central passage for movement between an unlocked position for mounting the implant on the distal locking portion, a locked position for locking the implant on the distal locking portion, and an insertion instrument deployed position for deploying the actuation plunger to move the blades from the stowed position to the deployed position. A spike cap drive rotatably mounts on the main body having a socket end for engaging a drive nut on the implant to, in turn, move the spike cap.

  • Patent number: 8882812
    Abstract: A bone plate assembly is disclosed which includes at least one plate segment having at least one aperture extending therethrough for receiving a head portion of a bone screw, and a structure supported by the plate segment and intersecting the aperture for retaining the head portion of the bone screw with respect to the plate segment.

  • Patent number: 8814915
    Abstract: A vertebral column construct for stabilizing a segment of a vertebral column can include first and second plate segments, and a spring connected between adjacent plate segments. The spring can be adapted and configured to provide a predetermined preload between the first and second plate segments. Such a preload can advantageously enhance fusion across a bone graft. Alternatively, the spring can be adapted and configured to resist, by a predetermined degree, loading between the first and second plate segments. A cam can be provided on one of the first and second plate segments, wherein engagement between the cam and the cam surface prevents dynamic connection between the first and second plates. The cam can be adapted and configured to adjust a preload applied between segments, such as by adjusting tension in the spring.

  • Patent number: 8523909
    Abstract: Spinal implants include an elongated body portion dimensioned and configured for percutaneous introduction into a target interspinous process space, at which interspinous distraction and/or spinal fusion are desired. The body portion can include a threaded outer surface, or alternatively a smooth surface. The body portion can include one or more interior cavities, and can include deployable engagement members adapted and configured to move in tandem between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body for engaging adjacent spinous processes. An internal drive assembly for selectively moving the engagement members from the stowed position to the deployed position can be provided, as can a elements for locking the engagement members in a deployed position.

  • Publication number: 20120078301
    Abstract: A spinal implant for treating lumbar spinal stenosis or as an adjunct to spinal fusion. The implant includes a body portion having an interior cavity. A plurality of locking wings are adapted and configured to move between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body portion. In the deployed position, the wings fix the implant in a selected interspinous space. A cable and wheel arrangement moves the plurality of locking wings from the stowed position to the deployed position and a ratchet/pawl assembly prevents backward movement of the wings.

  • Publication number: 20120063864
    Abstract: A fastening device including a fastener having a head portion and an elongated threaded body portion extending axially from the head portion. The threaded body portion includes opposing flat sections. A lock washer has a lower surface with an array of radially extending engagement teeth. The lock washer also defines an axial aperture for receiving the fastener. The axial aperture has two flat inner surfaces for cooperating with the two flat sections of the threaded body portion to prevent relative rotation of the washer and threaded body portion. A threaded lock nut mates with the threaded body portion. The lock nut has an upper surface with at least one cantilevered pawl members for ratcheted engagement with the array of radially extending engagement teeth of the lock washer.
