Minimally invasive spine augmentation and stabilization system and method

A system configured to augment a vertebral body, the system comprising:

• an expandable containment device that defines an interior device cavity;
• a cannula that defines a proximal cannula end, a distal cannula end spaced from the proximal cannula end, and a cannula passageway that extends between the proximal cannula end and the distal cannula end;
• a chassis that defines an interior chassis cavity that is configured to at least partially receive the expandable containment device, the chassis configured to be received in the cannula passageway, the chassis defining an insertion end and a trailing end opposite the leading end, the chassis extending along a chassis axis, the chassis having a first shape and a second shape that is different from the first shape, wherein moving the chassis from inside the cannula to outside the cannula causes the chassis to transition from the first shape to the second shape such that the chassis is curved along the chassis axis;
• and
• a sleeve that defines a sleeve passageway, the sleeve sized to be received in the cannula passageway, the sleeve configured to be detachably coupled to the chassis such that filler material can be introduced through the sleeve passageway and into the interior device cavity to expand the expandable containment device when the expandable containment device is at least partially disposed in the interior chassis cavity.
