  • Patent number: 10722380
    Abstract: Apparatus and associated methods relate to a laterally expandable spinal implant configured with pivoting wings adapted to secure the implant when inserted between vertebrae with stabilizing force applied to the vertebrae by shaft-driven wedges coupled with the wings. In an illustrative example, the wings may pivot along a hinge axis to swing outward from the implant central body until they press against vertebral endplates superior and inferior. The hinge may be, for example, disposed longitudinally to the implant central body. In some examples, four wings may be mounted axially in the implant central body. Some embodiments may include shaft-driven wedges coupled with the wings and adapted to force the wedges out laterally from the central body. Various examples may advantageously provide improved post-implant spinal stability, enhanced post-implant bone growth, and increased implant contact area with bone, based on the implant pressing the wings against the endplates as the shaft rotates.

  • Patent number: 10485675
    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.
