Abstract
A porous containment device for implanting into the interior volume of a targeted vertebral body for use in restoring the anatomy of the targeted vertebral body. The porous containment device is expandable from an insertion configuration to an expanded configuration via, for example, a bone filler material. The porous containment device includes an enlarged proximal portion, an enlarged distal portion, and a narrower central portion located between the enlarged proximal and distal portions. The porous containment device includes at least one pore positioned between a midline of the narrower central portion and walls of the enlarged distal and proximal portions. The porous containment device may include one or more air or fluid evacuation pores to permit air or fluid to escape and internal or external constraints to form the narrower central portion. In addition, a cannulated sleeve may be used to insert the porous containment device.
