  • Publication number: 20230293205
    Abstract: A magnetic screw device of a bone screw and one or more magnets that are attached to the bone screw. The bone screw may have a stem, which comprises a connector and at least one thread, and a housing assembly. The connector of the stem may be configured to articulate with the housing assembly such that the stem can rotate and angulate relative to the housing assembly. The magnetic screw device may be used to treat or stabilize spines with abnormal curvature, prevent further curvature progression, and relieve pain associated with abnormal curvature.

  • Patent number: 11678995
    Abstract: An intervertebral disc replacement device comprising a superior plate and an inferior plate, in which each plate contains one or more embedded magnets. The one or more magnets in the superior plate and the one or more magnet in the inferior plate are oriented such that a magnetic force exists between the one or more magnets in the superior plate and the one or more magnet in the inferior plate. In addition, an intervertebral disc replacement device comprising a superior plate and an inferior plate, in which each plate contains one or more embedded magnets, and the plates are designed to form an articulating surface. Further, an intervertebral disc replacement device comprising a superior plate, an inferior plate, and a spacer, in which each plate contains one or more embedded magnets, and the superior and inferior plates are designed to form articulating surfaces with the spacer.

  • Patent number: 10874518
    Abstract: Prosthetic implant devices and related methods are provided. The prosthetic implant devices include an internal component and an external component. The internal component has an implant portion associated with one or more rare earth magnets. The internal component being of a size and shape suitable for surgical implantation into the residual limb of the amputee. The one or more rare earth magnets generate at least one magnetic field. The external component having a prosthetic piston associated with a plurality of magnetic elements and a prosthetic cup associated with a magnetic array. The magnet elements of the prosthetic piston being in adaptable magnetic association with the at least one magnetic field generated by the one or more rare earth magnets.

  • Patent number: 10675152
    Abstract: Methods of reducing loading across a cartilaginous joint, or of reducing pain in a cartilaginous joint caused by cartilage damage in the joint. The methods involve implanting one or more magnetic devices in the bones, or affixing one or more magnetic devices onto the surface of the bones, that form the joint. For example, to reduce loading or reduce pain in a knee joint, one or more magnetic devices maybe implanted in the femur and in the tibia. The magnetic devices are oriented to generate a repulsive magnetic force between the one or more magnetic devices of each of the bones forming the joint.
