  • Patent number: 11000290
    Abstract: This invention is the method of treating an ailment associated with the cervical portion of the spine by performing an intravertebral corpectomy that includes the steps of removing the vertebral corpus to define a working channel for the surgeon to gain access to the epidural space so as to attend to and perform a procedure on the pathology. This method obviates the problems incidental to more radical cervical spine operations such as discectomy or corpectomy which requires removal of a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves and using a bone graft with or without a metal plate and screws to reconstruct the spine and provide stability. Prior to terminating the surgery, the opening formed by the removed vertebral corpus is fitted and/or filled with a suitable implant.

The cages may have integrated ratchet assemblies that allow the cage to change size and angle as needed, with little effort. The cages may have a first, insertion configuration characterized by a reduced size to facilitate insertion through a narrow access passage and into the intervertebral space. The cages may be inserted in a first, reduced size and then expanded to a second, larger size once implanted. In their second configuration, the cages are able to maintain the proper disc height and stabilize the spine by restoring sagittal balance and alignment. Additionally, the intervertebral cages are configured to be able to adjust the angle of lordosis, and can accommodate larger lordotic angles in their second, expanded configuration. Further, these cages may promote fusion to further enhance spine stability by immobilizing the adjacent vertebral bodies.

  • Patent number: 10864086
    Abstract: An expandable intervertebral spacer has a plurality of arms. The arms can be retracted or extended. The spacer has a width that is narrower than the width between the nerve roots near the posterior approach to an intervertebral space. Once inserted into the intervertebral space, the arms can be deployed. The deployed arms expand the height and width of the spacer. Once deployed, the spacer stabilizes two adjacent vertebrae. The arms are interconnected mechanically to deploy simultaneously.

  • Patent number: 10842640
    Abstract: An implant is insertable in the joint space to separate bones of the joint. The implant has two endplates each configured to engage a separate articulating bone of the joint, and a threaded member positioned between the two endplates and configured to increase the space between the two endplates when the threaded member is rotated. A rotatable gear is engaged with the threaded member, and is engageable with a rotating gear of a connected implantation tool, so that rotation of the gear on the tool causes rotation of the threaded member and expansion of the implant to separate the bones. Connector portions on the tool and the implant may be rotated together to securely engage the implant and the tool so that the gears of the tool and the implant can be rotated using an actuator outside of the body, when the implant is inside the body.
