  • Adjustable implant and method of use
    Patent number: 10039661
    Abstract: A system includes an adjustable implant configured for implantation internally within a subject and includes a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system includes an external adjustment device configured for placement on or adjacent to the skin of the subject having at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet and an encoder. Rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. Drive control circuitry is configured to receive an input signal from the encoder.

  • INTERBODY FUSION IMPLANT AND RELATED METHODS
    Publication number: 20180214279
    Abstract: An implant for performing interbody fusion within a human spine, inserters for such an implant, and associated methodology. The implant is preferably formed in situ from at least two separate but lockable members (a base member and a closure member). The base member may be implanted into an interbody space first, after which the end plates may be finally prepared and the base member packed with fusion promoting substances before engaging and locking the closure member. The closure member provides structural support for the adjacent vertebral bodies (along with the base member) and may be selected after implantation of the base member having a specific length, width, height, taper, etc. . . . to ensure an optimal sizing of the implant for desired restoration of disc height, coronal taper, sagittal taper, etc. . . .
