  • Patent number: 12109128
    Abstract: An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.

  • Publication number: 20240245526
    Abstract: An intervertebral implant comprising a body formed as an open truss structure, the body having a generally annular shape with a superior surface, an inferior surface, and a perimeter surface extending around an outer periphery of the body. The body may have a central portion and a peripheral portion, the peripheral portion extending inward from the perimeter surface toward the central portion, the peripheral portion including a first set of trusses, and the central portion including a second set of trusses. The implant may further include a strut at least partially defining a boundary between the central portion and the peripheral portion, wherein the strut has an oblong cross-sectional shape oriented to facilitate flow of bone graft material in a substantially radial direction away from the central axis.

  • Patent number: 11642227
    Abstract: A dynamic disc assembly has a superior end plate, an inferior end plate, and a core. The core has surfaces of an annular Fresnel shape and a linear Fresnel-like shape combined to control the dynamic range of motion (ROM) movement arranged to match anatomical ROM. The core is interposed between and held against interior surfaces of the superior end plate and the inferior end plate. The assembly further has a pair of coupling cords, one coupling cord at each lateral end of the superior and inferior end plates wherein each lateral end of each end plate has one or more cord connections attached and affixed to the coupling cord to form and retain the dynamic disc assembly.
