Having Opposed Bone-plates Which Moves Relative To One Another Patents (Class 623/17.15)
  • Patent number: 11324605
    Abstract: A prosthetic intervertebral disc is formed of first and second end plates sized and shaped to fit within an intervertebral space and to be implanted from the back of the patient, thereby decreasing the invasiveness of the procedure. The posterior approach provides for a smaller posterior surgical incision and avoids important blood vessels located anterior to the spine particularly for lumbar disc replacements. The first and second plates are each formed of first, second and third parts are arranged in a first configuration in which the parts are axially aligned to form a low profile device appropriate for insertion through the small opening available in the TLIF or PLIF approaches described above. The three parts of both of the plates rotate and translate with respect to one another in situ to a second configuration or a deployed configuration in which the parts are axially unaligned with each other to provide a maximum coverage of the vertebral end plates for a minimum of insertion profile.

  • Patent number: 11304821
    Abstract: Apparatus and associated methods relate to a spinal implant configured to expand both vertically and laterally at the same time when wedges coupled by a threaded post drive movable spinal implant endplates radially outward from the longitudinal axis of the threaded post, displacing the wedges and expanding the implant as the threaded post turns. In an illustrative example, the wedges may be a pair of wedges configured with dual inclined planes. The inclined planes may be, for example, disposed both vertically and laterally with respect to the threaded post longitudinal axis, permitting implant expansion both vertically and laterally simultaneously. In some examples, the wedges may be cones. Some embodiments may include an aligning support. In some samples, the aligning support is a pair of rails adapted to prevent rotation of the wedges.

    Abstract: An expandable anterior lumbar interbody fusion device comprises a multiple piece construction that includes an outer shell, movable upper and lower endplates and a pair of laterally spaced supports therebetween. The endplates are initially nested within the outer shell and telescope through the outer shell when expanded by a secondary instrument. Each endplate includes fixation elements to anchor the expanded device in an intervertebral disc space. Bilateral internal pockets are formed within each of the endplates to fully contain the supports. Once the device is expanded, the supports are pushed into place by the instrument in a manner to maintain the expanded position. After the supports are in place, the expander instrument is removed, and the device remains anchored in the expanded state.

  • Patent number: 10980589
    Abstract: An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.

  • Patent number: 10912653
    Abstract: An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

  • Patent number: 10898344
    Abstract: An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.

  • Patent number: 10898340
    Abstract: Interbody spacers are expandable horizontally and vertically by an application of axial force, and lockable in an expanded configuration. The spacers include support members interconnected to end bodies by pivotable link members. The spacers are introduced between vertebral bodies in a compressed configuration and expanded to fill the intervertebral space and provide support and selective lordotic correction. Graft material may be introduced into the expanded spacer. Provisional and/or supplementary locking means lock the spacers in the expanded configuration. Embodiments of the spacers include symmetrically and asymmetrically configured spacers. Methods of expansion include symmetric expansion or asymmetric expansion along each of two directions.

  • Patent number: 10842641
    Abstract: An implant (100, 200, 300, 400) includes a base (10), and a sequence of at least two segments including a first segment (12) and a last segment (14). The first segment (12) is pivotally linked to base (10). Adjacent segments are interconnected at pivotal connections (18). A bolt (20) has a threaded shaft (22) and a head (24). The threaded shaft (22) is engaged in a threaded channel (26) of the base (10) so that rotation of the bolt (20) about a central axis of the threaded shaft (22) varies a degree of overlap between the base (10) and the bolt (20). The last segment (14) and the head (24) define therebetween a spherical bearing (28). Rotation of bolt (20) thus varies a distance between spherical bearing (28) and hinge pin (16), thereby causing deflection of the sequence of segments.

  • Patent number: 10813773
    Abstract: A secondary cover plate that contacts a stand-alone fusion cage without rigidly connecting to the cage, and instead only docks against the cage (or passes through a fixation cage) and is secured into the adjacent bone. The secondary cover plate is the last item that would be added to the fixation cage construct and would at least partially cover the head of one or more angled screws. The secondary cover plate could slidably engage the fixation cage without permanently snapping into any features of the cage itself. The secondary cover plate would then be final positioned by advancing into one or more adjacent vertebral bodies. The secondary cover plate advancing step could be achieved by tapping it into place (into bone) so that it is finally secured into the bone.
