  • Spinal cage having deployable member
    Patent number: 8292958
    Abstract: 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.
