  • Patent number: 9402737
    Abstract: A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

  • Publication number: 20160058573
    Abstract: An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.

  • Patent number: 8900307
    Abstract: A two-piece fusion cage having ramped interior surfaces. One advantage of such a cage is its easy insertion. In a first step, the lower component is inserted into the disc space and is held in place. The first step confirms placement of the implant and its footprint. In a second step, the upper component is inserted into the disc space by sliding its interior surface along the opposed interior surface of the lower component. This two-step method of insertion eliminates the need to provide an independent distraction means.
