Patent ID: 8911497

Claim:
A system configured to augment a vertebral body, the system comprising: an expandable containment device that defines an interior device cavity, and further defines a leading end with respect to a direction of insertion of the expandable containment device into the vertebral body, and a trailing end that is opposite the leading end and spaced from the leading end substantially along a first direction; a chassis that defines an interior chassis cavity that is configured to at least partially receive the expandable containment device; a cannula that defines a proximal cannula end, a distal cannula end opposite the proximal cannula end, and a cannula passageway that extends between the proximal cannula end and the distal cannula end; a guidewire sized to be received in the cannula passageway and having distal guidewire end portion, wherein moving the distal guidewire end portion from inside the cannula to outside the cannula causes the distal guidewire end portion to change shape such that the distal guidewire end portion generally extends laterally across the vertebral body when the distal guidewire end portion is disposed inside the vertebral body; and a sleeve that defines a sleeve passageway, the sleeve sized and configured to be inserted into 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 along a second direction that is substantially perpendicular to the first direction when the expandable containment device is at least partially disposed in the interior chassis cavity, thereby causing at least a portion of the expandable containment device to be outwardly disposed with respect to the chassis along the second direction.
