  • MULTIPLE SPINDLE ADJUSTABLE INTERBODY FUSION DEVICES AND METHODS OF USE
    Publication number: 20190070015
    Abstract: An interbody fusion device includes a base member, a top member, and an expansion mechanism for moving the top member relative to the base member. The expansion mechanism may include a connector drive rod assembly, a gear, a threaded rod, and a support means. The gear ring is coupled to the threaded rod and is rotatable. The expansion mechanism may also include at least one load head coupled to the threaded rod. An alternative interbody fusion device is also disclosed and includes a bottom member, a superior member, and an expansion mechanism for moving the superior member relative to the base member, wherein the expansion mechanism comprises at least one expansion assembly for moving an end of the superior member relative to the bottom member.

  • Unidirectional dynamic interbody fusion device and method of use
    Patent number: 10143565
    Abstract: An interbody fusion device includes a top member, a base member, and an expansion member. The top member includes a first bone-engaging side and a threaded opening. The base member is received by the top member and includes a second bone-engaging side and an open cavity aligned with the threaded opening of the top member. The expansion member is disposed within the open cavity for rotation about an axis. The expansion member includes a threaded portion threadably engaged with the threaded opening. Rotation of the expansion member translates the first bone-engaging side away from the second bone-engaging side along the axis.
