Abstract
The present disclosure describes an intervertebral implant having a laterovertically-expanding shell operable for a reversible expansion from a collapsed state into an expanded state, the laterovertically-expanding shell having one or more connectors, and a pair of lateral extension elements that function to laterally expand the footprint of the implant within an intervertebal disc space.
Claims20
A surgical implant configured for placement within an intervertebral space, comprising:
- a laterovertically-expanding shell, the shell having a distal region and configured to create an intervertebral scaffolding system in vivo, the shell having a first body portion configured to engage a first vertebral endplate and a second body portion configured to engage a second vertebral endplate, the shell further including a collapsed state and an expanded state;
- and,
- wherein the shell is configured to extend asymmetrically from the longitudinal axis of the shim, extending further in the first lateral direction than in the second lateral direction to bias the profile of the implant in the first lateral direction after the expansion.
A surgical implant having a combination of materials combined in layers, comprising:
- a laterovertically-expanding shell having a distal region and configured to create an intervertebral scaffolding system in vivo, the shell having a layered assembly that includes a central layer and a plurality of surface layers;
- wherein,
- the central layer has a top face and a bottom face, and is configured to associate with the plurality of surface layers;
- the plurality of surface layers has a top surface layer and a bottom surface layer, the top surface layer configured to associate with the top face of the central layer and form a first body portion configured to engage a first vertebral endplate;
- and the bottom surface layer configured to associate with the bottom face of the central layer and form a second body portion configured to engage a second vertebral endplate;
- and,
- the shell has a collapsed state and an expanded state;
- wherein, the central layer and the plurality of surface layers comprise different materials.
