20100217323 | FORCED GROWTH AXIAL GROWING SPINE DEVICE - A forced growth axial growing spine device includes a central body portion having opposing ends. At least one housing is disposed at one end of the central body portion. The at least one housing includes a locking mechanism. At least one rigid member is coupled to the central body portion.

Additionally, the central body portion includes a cam and at least one port. One or more ball bearings may be inserted into the ports. Operation of the cam in conjunction with the ball bearing urges the rigid member away from the cam, thereby increasing an overall length of the forced growth axial growing spine device. | 08-26-2010 |

The treatment site may be an inter-vertebral motion segments in the lumbar and sacral regions of the spine. The tool set may comprise introducer tools and bone dilators for accessing and tapping into a targeted site, such as, for example, the anterior surface of the S1 vertebral body. The tool set may also comprise cutters and extractors for preparing the treatment site for subsequent treatment procedures. The tool set may additionally comprise a bone graft inserter, an exchange system, and/or a temporary distraction tool for further preparing the treatment site for subsequent treatment procedures. | 11-03-2011 |
20120310283 | SEGMENTAL SPINAL FIXATION SYSTEM AND A METHOD OF FIXATING A PLURALITY OF SPINAL SEGMENTS - A spinal fixation system includes a plurality of segmental members each having a concave end and a convex end, and aligned end to end with the convex end of one of the segmental members disposed within the concave end of an adjacent segmental member to define a segmental rod. The rod is formed for attachment to a plurality of spinal segments, and then tensioned to generate a stiffness in the segmental rod sufficient to maintain the pre-formed shape. A locking mechanism secures a tensile connector to the segmental rod and maintains the tension of the tensile connector once secured and the shape of the preformed segmental rod. The locking mechanism includes a crimping device through which the tensile connector passes, and a guide device through which the tensile connector wraps around. The crimping device is compressed to grasp and secure the tensile connector in place relative to the segmental rod. | 12-06-2012 |

20140058450 | SPINAL CORRECTION SYSTEM AND METHOD - A spinal construct comprises a first member defining a longitudinal axis and extending between a first end and a second end being offset relative to the longitudinal axis. A second member defines a longitudinal axis and extends between a first end and a second end being offset relative to the longitudinal axis of the second member. The second ends are connected to define an axis of rotation such that the members are relatively rotatable about the second ends and the axis of rotation is offset relative to the longitudinal axes. Systems and methods are disclosed. | 02-27-2014 |
20140088649 | ARTICULATING SPINAL ROD SYSTEM - An adjustable articulating spinal rod system including a first elongated element secured to a first bone, a second elongated element secured to the spine, and an articulating joint connecting the first and second elongated elements. The articulating joint including a first movable joint, a second movable joint, and at least one locking mechanism. The first movable joint is coupled to the first elongated element and the second movable joint which is also coupled the second elongate element. The first and second movable joints are configured to allow polyaxial movement and rotation of the first elongated element with respect to the second elongated element. The at least one locking mechanism immobilizes the first and second movable joints in the locked position to secure the first elongate element in a position relative to the second elongate element and allow movement and rotation in an unlocked position. | 03-27-2014 |
20140214083 | ARTICULATING ROD ASSEMBLY - An articulating assembly includes a first elongated element for attachment to a first anatomical region, and a second elongated element for attachment to a second anatomical region. In at least one embodiment, a coupling connects the first and second elongated elements. The coupling includes a moveable joint configured to allow polyaxial movement of the first elongated element with respect to the second elongated element. The assembly further includes a locking mechanism. The locking mechanism is operable in an unlocked condition to permit polyaxial movement of the first elongated element with respect to the second elongated element, and a locked condition to immobilize the movable joint and fix the position of the first elongated element with respect to the second elongated element. | 07-31-2014 |

The first end of the unit includes a female component with an interior dimension and the second end includes a male component having exterior dimension. The female component and the male component are capable of mating. At least one the female and male components also includes an adjustment mechanism with a first position that allows the component to rotate in a both a first rotational direction and a second rotational direction opposed to the first rotational direction, and a second position that prevents rotation of the component in the second rotational direction. | 12-29-2016 |
20160374729 | SYSTEM AND METHOD FOR DYNAMIC VERTEBRAL STABILIZATION - An intervertebral stabilization device and method is disclosed. The device preferably includes a planar spring enclosed within a housing. The housing is joined to an articulation component at either end, and the articulation components have couplings connectable to anchoring components which are securable to adjacent vertebrae. The planar spring can flex and retract providing relative motion between the adjacent vertebrae. The articulation components are ball and socket joints which allow the entire assembly to flexibly follow the curvature of the spine. A fusion rod with articulation components and couplings at either end may be substituted for the spring device. The couplings enable interchangeability between a fusion rod assembly and spring assembly, so that dynamic stabilization can occur at one vertebral level and fusion at the adjacent vertebral level. An overhung spring assembly with a sideways displaced housing which allows for a shorter pedicle to pedicle displacement is also disclosed. | 12-29-2016 |
