  • Publication number: 20240033100
    Abstract: Interbody implants may be formed by a product by process in which a first metallic frame component having an interconnected superior endplate and an interconnected inferior endplate are formed. In some embodiments, the endplates are interconnected by flexible struts and in others they are interconnected by translating struts. In various embodiments, a polymeric body may be infilled between the superior endplate and inferior endplate by a molding process, e.g., an injection molding process or an overmolding process. In various embodiments, the metallic frame may have a first compressive stiffness, the polymeric body may have a second compressive stiffness, and the first compressive stiffness of the metallic frame may be about 20% to about 80% of the second stiffness of the body. In various embodiments, a sum of the first compressive stiffness of the metallic frame and the second stiffness of the body is about 33,500 N/mm to about 11,500 N/mm.

  • Patent number: 11730608
    Abstract: A unibody implant movable between an expanded position and a contracted position is disclosed. The unibody implant may include a unitary expandable body defined by an inferior portion and a superior portion that are connected together. In various embodiments, a set screw may be rotatably supported by the body and configured to move a plug having a first inclined surface facing the distal side. In various embodiments, the set screw may be movable in the longitudinal direction towards the distal side upon rotation of the set screw along the rotation axis, for example. In various embodiments, movement of the set screw urges the plug against the superior portion thereby expanding a vertical distance between the superior and inferior sides of the body. In some embodiments, the plug may include a stabilizing element configured to transfer compressive forces between the superior portion and inferior portion.
