    Abstract: Provided are rod coupler devices, systems, kits and methods, which include at least one saddle having a concave configuration that either abuts a bone fastener and/or a locking cap and is shaped so as to contact the rod in two or more lines of contact, which reduces pressure on the rod, and therefore permits use of a rod having various materials, such as PEEK, without significant deformation of the rod. Also provided is the saddle itself and integrated locking caps that include a saddle, the locking cap and a set screw. Also provided are elongate rods having advantageous shapes, configurations, and/or compositions for rod coupler devices, systems and methods. Further provided are screw and cap devices and systems that themselves include a concave configuration so as to contact a rod in two or more lines of contact, which reduces pressure on the rod.

  • Patent number: 10512551
    Abstract: An interbody implant comprises one or more elongate members that have superior and inferior surfaces with a height, and medial and lateral surfaces having a width. The height is set so the implant fits into the intervertebral space. The width is less than the height. The interbody implant has a first configuration, a second configuration, and a third configuration. The interbody implant is inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, and the interbody implant is then actuated into the second configuration such that superior and inferior surfaces engage the vertebral bodies. Actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies. The implant is actuated into the third configuration where the width of the implant is greater than width of the implant in the first or the second configuration.

    Abstract: The present application discloses methods for treating a spinal deformity. In one embodiment, an elongated member is attached to vertebral members with fasteners. A separate fastener may attach the elongated member to each of the vertebral members. The elongated member may apply a force to limit growth on one side of the vertebral members, such as a convex side of a scoliotic spine. Each fastener may be constructed to limit a direction of growth of the vertebral member thereby applying a specific, corrective force to the vertebral member. The fasteners may allow relative motion between adjacent vertebral members without losing the attachment between the vertebral members and the fasteners. The net result may be controlled modulation of growth to reduce and/or eliminate the spinal deformity through redirection of growth potential.

  • Publication number: 20140257393
    Abstract: A flexible connection unit for use in a spinal fixation device is provided. The flexible connection unit includes an elongated member, such as a vertebral rod, having a first end portion and a second end portion opposite each other with a transition portion extending therebetween. The first end portion of the vertebral rod comprises an oval shape and the second end portion contains an oval or non-oval shape. The major diameter of the oval shaped first end is parallel to the sagittal plane of a patient's body and provides the higher stiffness for fusion to resist flexion in the sagittal plane. The second end portion of the vertebral rod is perpendicular to the sagittal end of a patient's body and provides the lower stiffness for fusion.

  • Patent number: 8795277
    Abstract: A bone reconstruction device (100, 200, 300) is provided that includes an elongated linkage (102, 202, 302) having a plurality of links (104, 204, 304). The reconstruction device further includes an adjustment assembly (120, 220, 320) that provides for adjustment of the directional and/or angular orientation of the links. The reconstruction device further includes a locking assembly (122, 222, 322) that is movable between a disengaged configuration and an engaged configuration. In the disengaged configuration, the adjustment assembly can be actuated to adjust the orientation of the links. In the engaged confirmation, the locking assembly inhibits adjustment of the orientation of the links.

  • Publication number: 20140180339
    Abstract: A dynamic fixation device is provided that allows the vertebrae to which it is attached to move in flexion within the normal physiological limits of motion, while also providing structural support that limits the amount of translation motion beyond normal physiological limits. The present invention includes a flexible portion and two ends that are adapted for connection to pedicle screws. In at least one embodiment of the present invention, the normal axis of rotation of the vertebrae is substantially duplicated by the dynamic fixation device. The flexible portion of the dynamic fixation device can include a geometric shape and/or a hinge portion.

  • Patent number: 8758410
    Abstract: A modular anchoring device including a threaded shank for anchoring within a vertebra, an intermediate element and a head portion configured to receive and secure a rigid or non-rigid stabilization rod. The threaded shank, the intermediate element and the head portion of the anchoring device are cannulated to permit percutaneous implantation of the device. The intermediate portion is designed to be removable from the threaded shank portion subsequent to implantation of the anchoring device to enable substitution of another intermediate element having different dynamic characteristics.

  • Publication number: 20140148854
    Abstract: A vertebral fixing system having a flexible elongated member, a connecting part, and an anchor, where the anchor may engage a bone structure (e.g., a vertebra) through an opening of the connecting part and the flexible elongated member may connect to the connecting part. In some cases, the vertebral fixing system may include a tightening part configured to apply a tension to the elongated member and/or secure the elongated member with respect to the connecting part. The vertebral fixing system may be configured to receive a rod and may be capable of connecting thereto. The connecting part may have a plurality of connecting members, where at least one of the connecting members includes an opening for receiving the anchor and at least one of the connecting members connects to the elongated member.

  • Patent number: 8663284
    Abstract: A connecting element for a spinal column stabilization system includes a first attachment section for fixing to a first bone attachment device, a second attachment section for fixing to a second bone attachment device and an at least partially flexible intermediate section. The intermediate section is arranged between the first and the second attachment section and is in the form of a strip-like, winding leaf spring element having at least one recess. A desired spring stiffness is maintained as precisely as possible, especially in the intermediate section independently of possible manufacturing tolerances arising from the manufacturing process. At least one of the two leaf spring element surfaces of the leaf spring element includes at least one stiffness-modifying element. The connecting element may be part of an improved spinal column fixation system and made by an improved method of manufacturing a connecting element.
