  • Variable lordosis spacer and related methods of use
    Patent number: 9839528
    Abstract: An expandable fusion device may include a first endplate and a second endplate. The expandable fusion device may also include first and second ramps configured to mate with both the first and second endplates. The first ramp may include a mating feature having a first angle relative to a vertical axis, and the second ramp may include a mating feature having a second angle relative to the vertical axis such that the first angle is different from the second angle. In particular, the first and second ramps may be configured to provide for symmetrical expansion of the first and second endplates.

  • Expandable intervertebral implant
    Patent number: 9833336
    Abstract: An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.

  • EXPANDABLE FUSION DEVICE AND METHOD OF INSTALLATION THEREOF
    Publication number: 20170333203
    Abstract: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

  • Variable angle connection assembly
    Patent number: 9814492
    Abstract: A connection assembly configured to securely connect a spinal implant to a bone anchor. In particular, a variable angle connection assembly that is able to securely connect the spinal implant to the anchors even when there is a variance in the angle and position of the anchors with respect to the spinal implant. Furthermore, a connection assembly that will not inadvertently lock the components of the connection assembly preventing the relative movement of the components.

  • Articulating and expandable vertebral implant
    Patent number: 9782265
    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.

  • EXPANDABLE VERTEBRAL IMPLANT
    Publication number: 20170035577
    Abstract: A joint spacer therapeutically maintains separation of bones of a joint. A carriage is slideably retained within the frame and has at least one ramped surface. An actuator screw is threadably engaged with the frame, and rotatably connected to the carriage, to cause the carriage to slideably move within the frame when the actuator screw is rotated. First and second endplates engage the bones of the joint, and each has at least one ramped surface that is mateable with the ramped surface of the carriage, whereby when the carriage is slideably moved by rotation of the actuator screw, the endplates ramped surface slides against the carriage ramped surface to cause the endplates to move along an axis transverse to the longitudinal axis of the frame, to increase the height of the spacer. Piercing elements are connected to the carriage to pierce bone of the joint when the carriage is moved.
