1. An intervertebral disc implant, comprising:
an expandable cage assembly configured to expand from a collapsed state to an expanded state in an intervertebral space when inflated with a material, the expandable cage assembly comprising:
an inflatable section defining an interior volume configured to receive the material and expand the interior volume in response to a pressure from the received material to cause the expandable cage assembly to transition from the collapsed state to the expanded state, and
a stabilization section configured to restrain the inflatable section during inflation,
wherein the inflatable section comprises a textile substrate, and
wherein the stabilization section comprises a 3D scaffold that is printed onto the textile substrate and configured to restrict further expansion of the textile substrate in the expanded state.
