  • Patent number: 9717541
    Abstract: Lamina plates can include various features that allow a surgeon to couple the plate to a vertebra, such as a plurality of receiving holes for receiving a spinal fixation element. The plate can be shaped and the receiving holes positioned such that spinal fixation elements can be installed with reduced exposure of the spine and along a trajectory that enhances purchase with bone. The lamina plate can include one or more features for coupling at least one receiver head to the plate for receiving a spinal stabilization element. Since the receiver head can be coupled to the plate after the plate is implanted, it does not restrict the range of angles or trajectories at which the spinal fixation elements can be installed.

  • Patent number: 9707017
    Abstract: An interspinous process spacer implant includes first and second bodies each equipped with upper and lower projections. The implant also includes a hinge connecting central parts of the bodies to one another. The hinge allows the bodies to rotate relative to one another in a forward direction. The implant further includes an arresting mechanism that acts between the central parts of the bodies to block reverse rotation of the bodies relative to one another.

  • Patent number: 9572603
    Abstract: An implantable spacer for placement between adjacent spinous processes in a spinal motion segment is provided. The spacer includes a body defining a longitudinal passageway. A first arm and a second arm are connected to the body. Each arm has a pair of extensions and a saddle defining a U-shaped configuration for seating a spinous process therein. An actuator assembly is disposed inside the longitudinal passageway and connected to the body. When advanced, the actuator assembly contacts camming surfaces of the arms to rotate them from an undeployed configuration to a deployed configuration. In the deployed configuration, the distracted adjacent spinous processes are seated in the U-shaped portion of the arms providing sufficient distraction to open the neural foramen. An insertion instrument is provided for implanting the interspinous process spacer. The system is configured for implantation through a small percutaneous incision employing minimally invasive techniques.

  • Patent number: 9561060
    Abstract: The present invention provides spinous process implants and associated methods. In one aspect of the invention, the implant includes at least one extension with a superior lobe pivotally connected to an inferior lobe, such as by a hinge, to allow unfolding of the at least one extension from a folded position to an unfolded position. In certain aspects, the folding extension may include fasteners to facilitate engagement with the spinous processes to provide both a flexion stop as well as an extension stop. The fasteners may have corresponding bores to allow the fasteners to reside in the bores to provide a compact profile for implantation. In another aspect of the invention, the implant is introduced to the surgical site using a lateral or paramedian approach and associated tools to facilitate the same.

  • Patent number: 9480502
    Abstract: A device and method for performing interspinous fixation or spinal fusion is provided. The device may generally include a first plate and a second plate, each having an adjustable length, and a mechanical actuator for increasing or reducing the length of the plates and, correspondingly, the device. Operation of the mechanical actuator causes first and second inner expansion portions of each plate to simultaneously slide on an outer fixed portion of the plate, to increase or decrease (depending on the direction of operation of the mechanical actuator) the separation between the first and second inner expansion portions, and thus, lengthen or shorten the plates and device.
