Porous containment device and associated method for stabilization of vertebral compression fractures
First Claim
1. A porous containment device for implantation in an interior volume of a targeted vertebral body, the porous containment device comprising an outer surface defining an interior cavity for receiving a bone filler material;
- the porous containment device further including;
a proximal portion, a distal portion, and a central portion located between the proximal and distal portions;
wherein the porous containment device is expandable from an insertion configuration to an expanded configuration via injection of a bone filler material into the interior cavity of the porous containment device and when the device is in the expanded configuration, the proximal and distal portions are enlarged and the central portion has a smaller diameter relative to the enlarged proximal and distal portions; and
wherein the porous containment device includes at least one pore configured to secrete the bone filler material into an area between the enlarged proximal and distal portions, the enlarged proximal and distal portions being sized and shaped such that the secreted bone filler material is semi-contained in said area.

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.
