  • Patent number: 11376134
    Abstract: An expandable implant movable between a contracted position and an expanded position, is disclosed. In various embodiments, the implant may be defined by a superior endplate and an inferior endplate having proximal ramps and distal ramps disposed on an interior surface thereof, respectively. The expandable body may include a beveled hook portion at a distal end thereof. In various embodiments, upon rotation of a proximal set screw, a proximal wedge may act against the proximal ramps of the superior and inferior endplates and cause the implant to expand at the proximal end. Upon rotation of a distal set screw, a distal wedge may act against the distal ramps of the superior and inferior endplates and cause the implant to expand at the distal end. In some embodiments, both the superior and distal set screws may be rotated simultaneously.

  • Publication number: 20220133488
    Abstract: A rhomboid shaped spinal implant may include a proximal surface that extends from a first lower end to a first upper end thereof a first distance, and a distal surface that extends from a second lower end to a second upper end thereof a second distance. The implant may include a superior surface that extends from the first upper end of the proximal surface to the second upper end of the distal surface a third distance, and an inferior surface that extends from the first lower end of the proximal surface to the second lower end of the distal surface a fourth distance. In various embodiments, the first distance is greater than the second distance, and the third distance is less than the fourth distance. In some embodiments, at least one bone screw aperture defines a trajectory extending in a direction substantially perpendicular to the superior and/or inferior surface.

  • Patent number: 11291554
    Abstract: A unibody implant movable between an expanded position and a contracted position is disclosed. The implant may include a unitary expandable body defined by an inferior portion, a superior portion, and a medial portion that are connected together. The unibody implant may include a first set screw and a second set screw rotatably supported by the body. The first set screw may have a first inclined surface facing a proximal side and the second set screw may have a second inclined surface facing a distal side. The medial portion may include a first inclined ramp and the superior portion may include a second inclined ramp. Movement of the first set screw towards the proximal side urges the first inclined surface against the first inclined ramp and movement of the second set screw towards the distal side urges the second inclined surface against the second inclined ramp.

  • Publication number: 20220039843
    Abstract: A spinal implant comprises at least one bone fastener including a proximal portion configured for fixation with a first anterior cortical surface of a vertebra and a distal portion configured for fixation with a second cortical surface of the vertebra. The proximal portion is engageable with a surgical driver having a surgical navigation component that generates data for display of an image representing position of the spinal implant relative to the vertebra. The spinal implant can be employed with cervical, thoracic, lumbar and/or sacral regions of a spine. Systems, surgical instruments and methods are disclosed.
