  • Expanding intervertebral implants
    Patent number: 11179242
    Abstract: A joint spacer has first and second endplates, with each having a bone engaging surface, and at least two cams with an inclined cam surface positioned on an opposite side. First and second slides, each having ramps with an inclined surface are engaged with the cams of the endplate. The first slide has an angled portion at an end, and the second slide has a hinge portion. A threaded shaft has a hinge portion connected to the slide hinge portion, connecting the shaft to the slide, enabling the shaft to pivot. A nut is threaded to the shaft, and can contact and interfere with the angled portion of the first slide to drive the first slide with respect to the second slide. This results in engagement of the cams and ramps to drive the endplates apart to increase the spacer height.

  • Intervertebral implant
    Patent number: 11179246
    Abstract: The present invention provides an intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine. The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion rigidly coupled to the spacer portion, wherein the plate portion contains holes for receiving screws. A fastener back out prevention mechanism adapted on the plate to prevent the back out of the fasteners from the holes and to secure the spacer to the plate of the intervertebral implant.

  • Expandable Vertebral Implant
    Publication number: 20210338453
    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.

  • STABILIZING VERTEBRAE WITH ARTICULATING IMPLANTS
    Publication number: 20210186709
    Abstract: A bone joint spacer has two endplates which have a bone engaging surface on one side, and ramps extending from an opposite side. A shaft has a threaded end, and another end which has ramp followers which mate with the endplate ramps of both endplates. A collar slides over the threaded end of the shaft, and also has ramp followers which mate with the endplate ramps of both endplates. A nut threads onto the end of the shaft and pushes the collar towards the ramp followers of the shaft. This movement causes the ramp followers to slide the ramp followers of the collar and the shaft against the endplate ramps, pushing the endplates apart. Two of these spacers can be combined by a link plate so that the spacers can be aligned or curved into a U-shape to be inserted into the body and positioned between bony surfaces, respectively.
