  • Publication number: 20170071635
    Abstract: A device and method for coupling first and second elongate spinal fixation elements. The device includes first and second connector members, for receiving first and second elongate spinal fixation elements respectively. One or both connector members may include an engagement portion configured and dimensioned to provisionally receive an elongate fixation element with an interference fit. First and second connector members are coupled to a translation member, the translation member operatively associated with at least one connector member to provide for polyaxial movement. At least one locking member is provided to secure a received elongate spinal fixation element in the engagement portion and lock polyaxial movement of the at least one connector member. The translation member may have first and second portions which move relative to each other with translation movement, and a third locking member to lock the translation movement.

  • Patent number: 9572677
    Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

  • Patent number: 9271842
    Abstract: The present invention relates to a method of inserting an implant comprising providing a trial assembly. The method may further comprise positioning the trial assembly between vertebrae in a patient. The method may further comprise rotating a drive shaft of the trial assembly to cause upper and lower gear members of the trial assembly to rotate causing expansion of a tip assembly of the trial assembly. The method may further comprise measuring expansion of the trial assembly with a scale at a proximal end of the trial assembly. The method may further comprise removing the trial assembly from the patient. The method may further comprise positioning an implant between the vertebrae in the patient. The method may further comprise expanding the implant based on the measured expansion of the trial assembly.

  • Publication number: 20160030091
    Abstract: Devices and methods for coupling first and second adjacent vertebrae. The device includes a first coupling element and a second coupling element. The first coupling element has a first body portion for receiving a first bone fastener and an elongate rod portion extending transversely from the first body portion. The second coupling element has a second body portion for receiving a second bone fastener and an extension portion extending transversely from the second body portion. The extension portion defines a recess sized and configured to receive the rod portion of the first coupling element. When unlocked, the rod portion is moveable in the recess to allow for rotational and translational movement of the first and second coupling elements. When locked, the relative position of the first and second coupling elements is fixed.
