  • Patent number: 10687876
    Abstract: A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screws include a threaded tip connected to a main shaft and a threaded outer sleeve that rotates relative to the outer shaft until locked down. Independent rotation of the threaded outer sleeve relative to the threaded distal tip allows compression or distraction to modify the gap between the vertebral bodies. The screws are passed from the inferior to superior vertebra or superior to inferior, for example, through a trans-pedicular route to avoid neurological compromise. At the same time, the path of screw insertion is oriented to reach superior or inferior vertebra. An intervertebral cage of the system is configured for lateral expansion from a nearly straight configuration to form a large footprint in the disc space. The screws and cage may be combined for improved fixation with minimal invasiveness.

  • Patent number: 10682240
    Abstract: A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

  • Patent number: 10617530
    Abstract: A laterally deflectable asymmetric implant for implanting into a body may comprise a deflectable piece having distal and proximal ends and assuming a straightened insertion state. The backbone may abut or interconnect with said deflectable piece at the distal end of the deflectable piece. In a fully deflected state the implant may define an asymmetric shape, e.g. a D-shaped loop, defining an at least partially enclosed volume. The deflectable piece may comprise a sequence of segments interconnected at effective hinges. Longitudinal pressure applied to the proximal end of the deflectable piece (or applied to the backbone in an opposite direction) may cause relative longitudinal movement between the backbone and the proximal end of the deflectable piece and may generate outward horizontal movement of the deflectable piece away from the backbone. In one embodiment, the implant is implanted using lateral access into an anterior zone of a vertebra and deployed posteriorly.

  • Patent number: 10500063
    Abstract: A modular anterior lumbar interbody fusion device comprises a monolithic interbody fusion cage and a modular plate resiliently attached thereto. The cage includes an open architecture with top and bottom cross members and a pair of opposing arms projecting from respective side structures of the cage to define a pocket at the cage anterior end. The modular plate is received in the pocket and attached to the cage by resilient latches. The plate lies fully within the profile of the cage with the resilient latches lying fully within the thickness of the plate. The plate provides a structure to close the anterior portion of the modular cage after introduction of bone graft material while allowing for use with integrated fixation. Attachment features between the monolithic cage and modular plate are universal allowing for selection of various modular device configurations with minimal components.

    Abstract: An intervertebral implant may include an input for expanding at least two extendable support elements connected to a body at respective locations, such that the extendable support elements each apply a respective expansion force directed away from a surface of the body. Application of a single input force to the input may induce the extendable support elements to apply different amounts of expansion force. Alternatively or additionally, an intervertebral implant may include at least two portions connected together by a hinge for articulation about the hinge. In one aspect, the hinge may include at least two rigid links each pivotably connected to the two portions.
