A bone support and/or barrier device and having an implantable structure including an outer surface, an inner surface, a first bone contact portion, and a second bone contact portion. The structure is collapsible to an undeployed configuration capable of percutaneous insertion to the interior of a bone and expandable to a deployed configuration in the bone. In the deployed configuration, the first bone contact portion contacts a first portion of the bone, and the second bone contact portion contacts a second portion of the bone such that a load placed on the first portion of the bone is transferred through the implantable structure to the second portion of the bone. The implantable structure includes a barrier material adapted to restrict bone filler material inserted into the bone adjacent the inner surface of the structure from flowing to the outer surface of the structure. A method is also disclosed.
