Adjustable distraction cage with linked locking mechanisms

摘要

A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

1. An expandable implant comprising:
a body having a first surface and a second surface; a first member formed within the body, the first member being actuatable to expand along a first axis to extend the first surface away from the second surface; a second member actuatable to expand in a lateral direction transverse to the first axis, the second member being actuatable independently of the first member.
