1. A system for accessing and inserting a containment device within an interior volume of a vertebral body, the system comprising:

  • an expandable containment device including an outer surface encasing an interior cavity;

    a chassis including an interior cavity for at least partially enclosing the expandable containment device;

    a first guidewire;

    a working cannula including a proximal end, a distal end and a hollow interior passageway extending from the proximal end to the distal end;

    a second guidewire having at least a partially flexible distal end portion such that the distal end portion generally extends laterally across an anterior portion of the vertebral body when the second guidewire extends out of the cannula in an insertion position; and

    a sleeve including a proximal portion, a distal portion and a cannulated passageway extending from the proximal portion to the distal portion, the sleeve being sized and configured to be inserted into the interior passageway of the working cannula, the distal portion of the sleeve being detachably coupled to the chassis, the proximal portion being operatively associated with a bone filler injecting mechanism for introducing bone filler material through the cannulated passageway of the sleeve and into the interior cavity of the containment device.
