Laterovertically-expanding fusion cage systems
First Claim
1. An intervertebral scaffolding system, comprising;
- a laterovertically-expanding frame configured to create an intervertebral scaffolding system in vivo, the frame havinga first top beam, a second top beam, a first bottom beam, and a second bottom beam, wherein the beams are in an at least substantially parallel arrangement with each other;
a plurality of top connector elements configured to expandably connect the first top beam to the second top beam;
a plurality of bottom connector elements configured to expandably connect the first bottom beam to the second bottom beam;
a top tensioner operably attaching the first top beam to the second top beam;
a bottom tensioner operably attaching the first bottom beam to the second bottom beam; and
,a stabilizer that slidably engages with the first top beam, the first bottom beam, the second top beam, the second bottom beam, or a combination thereof, and is configured for retaining the first top beam, the first bottom beam, the second top beam, the second bottom beam, or the combination thereof, from a lateral movement that exceeds the expanded state.

Abstract
An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.
