Abstract
A minimally invasive system and method for vertebral body augmentation includes an expandable containment device, a chassis including an interior cavity for at least partially enclosing the expandable containment device, a first guidewire, a working cannula, a second guidewire having at least a partially flexible distal end portion and a sleeve for introducing bone filler material through a cannulated passageway of the sleeve and into an interior cavity of the containment device. The containment device preferably includes a plurality of pores for directing the outflow of bone filler material anteriorly within the vertebral body. The containment device and chassis are left interior to the vertebral body subsequent to height restoration and augmentation of the vertebral body.
