Abstract
The invention relates to a cement director for insertion within a vertebral body or other body structure, and related methods of use. An example method includes creating a cavity in a vertebral body, inserting a collapsible mesh structure into the cavity in a collapsed state, wherein the collapsible mesh structure comprises regions of different permeability to a bone cement, inflating a balloon within the collapsible mesh structure to expand the mesh structure, and injecting a bone cement into the mesh structure, wherein the bone cement flows preferentially out of the mesh structure through at least one region of greater permeability.
