A spinal cage with a wall extending in a longitudinal direction defining an interior space is disclosed. There is also provided a deployable element in movable relation to the spinal cage.

Spinal cage having deployable member

A delivery instrument for placing an interbody implant into an intervertebral space of a patient comprises a plurality of elongated plates disposed adjacent one another. Each elongated plate has a proximal portion and a distal portion. The distal portion is sized and shaped to fit into the intervertebral space, and is configured to engage a vertebral body in the intervertebral space. An expandable member is coupled to the plurality of elongated plates so as to form an enclosed tube that is sized and shaped to receive the interbody implant. The expandable member allows for translation of the plurality of elongated plates relative to one another as the interbody implant passes through the tube.

Methods and apparatus for an insertion guide device

An interbody implant comprises one or more elongate members that have superior and inferior surfaces with a height, and medial and lateral surfaces having a width. The height is set so the implant fits into the intervertebral space. The width is less than the height. The interbody implant has a first configuration, a second configuration, and a third configuration. The interbody implant is inserted into the intervertebral space in the first configuration such that medial and lateral surfaces contact the vertebral bodies, and the interbody implant is then actuated into the second configuration such that superior and inferior surfaces engage the vertebral bodies. Actuation of the implant from the first configuration to the second configuration distracts the vertebral bodies. The implant is actuated into the third configuration where the width of the implant is greater than width of the implant in the first or the second configuration.

Methods and apparatus for implanting an interbody device

A spinal cage with a wall extending in a longitudinal direction defining an interior space is disclosed. There is also provided a deployable element in movable relation to the spinal cage. In some embodiments, there is a rib, and the rotatable member is engaged at one end with the wall and at the other end with the rib. In some embodiments, the spinal cage is provided with holes for screws that can be directed at adjacent vertebrae for fixation. Such a spinal cage can be used with the spin-plate or with the screws. The screws and the spinal cage may have features that cooperate to prevent back-out of the screws.

An implant may provide a body capable of being fit in an intervertebral space and a spin-plate rotatable with respect to the body. The spin-plate may a blade. The blade may possess grooves in its flat faces, or may be provided with an overhang. The path of the overhang or groove may be such that as the spin-plate advances in its rotation, a vertebra engaged with the blade is drawn toward the body of the implant. Pins may be placed in adjacent vertebrae such as to engage the spin-plate. Surgical methods are also described.

Deployable member for use with an intervertebral cage

Embodiments are disclosed which provide a spinal cage with a wall extending in a longitudinal direction defining an interior space. There is also provided a spin-plate that may be assembled into the spinal cage. The spin-plate may comprise a blade and a disc on a common shaft, and may be rotatable from an undeployed position to a deployed position. In some embodiments, the spin-plate may be assembled into the spinal cage by a translational motion perpendicular to a rotational axis of the spin-plate. The spin-plate may be captured in the spinal cage for certain angular positions. In some embodiments, there may be a snap-in feature when the spin-plate is assembled into the spinal cage, and there may be a rotational feature such that increased torque is required to advance beyond certain points.
