BONE SUPPORT AND BARRIER DEVICE, SYSTEM, AND METHOD

摘要

A bone support and/or barrier device, system, kit, and method can include an implantable structure having an outer surface, an inner surface, a first bone contact portion, and a second bone contact portion. The structure can be 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 can contact a first portion of the bone, and the second bone contact portion can contact a second portion of the bone such that a load placed on the first portion of the bone can be transferred through the implantable structure to the second portion of the bone. The implantable structure can include a barrier material adapted to restrict a bone filler material inserted into the bone adjacent the inner surface of the structure from flowing to the outer surface of the structure.
