  • Patent number: 8852280
    Abstract: Implants for positioning between vertebral members. The implant may include a superior surface to contact against a first vertebral member, and an inferior surface to contact against a second vertebral member. The implant may include a central web that extends between first and second flanges. The flanges may be shaped to form gaps that extend the height of the implant. Spaces in communication with the gaps may be formed in an interior of the implant to hold bone growth material.
    Type: Grant

  • Patent number: 8613761
    Abstract: The present application is directed to an implant maintained within the patient by a fastener. The implant includes an aperture sized to receive the fastener. A locking member extends across the aperture in a first position. The locking member is constructed of a resilient material that is movable to a second position during insertion of the fastener. Once the fastener is inserted within the aperture below a level of the locking member, the locking member rebounds towards the first position and extends over the fastener. The locking member prevents the fastener from backing out of the implant.

  • Patent number: 8465547
    Abstract: Methods and devices for spacing vertebral members using modular intervertebral devices and insertion tools. The devices may include opposing first and second endplates, and an intermediate member configured to fit between and support the endplates. The insertion tool may include an elongated handle and a distracter. A method of inserting the device using the tool may include inserting the endplates positioned on opposing sides of the handle into the intervertebral space and positioning the endplates in the intervertebral space relative to first and second vertebral members. The method may include deploying the distracter and increasing a distance between the endplates. Another step may include inserting the intermediate member into the intervertebral space and between the endplates and supporting the endplates with the intermediate member. The insertion tool may then be removed from the intervertebral space.

  • Publication number: 20100137916
    Abstract: In some aspects, the spinal plates of the present disclosure are sized and shaped for use in a spinal level adjacent to a previously treated spinal level. The spinal plates of the present disclosure are generally no-profile or low-profile plates. That is, the spinal plates are sized and shaped for positioning entirely within the disc space between adjacent vertebrae such that the plates either do not extend beyond the outer boundaries of the vertebrae (no profile) or extend only slightly beyond the outer boundaries of the vertebrae (low profile). The spinal plates of the present disclosure are also configured to receive fixation members, such as bone screws, in a hyper-angulated orientation. The hyper-angulated screws facilitate optimal cortical bone purchase or penetration of the adjacent vertebrae to fixedly secure the spinal plates to the vertebrae.
