Abstract
An apparatus according to the invention may comprise one or more expandable structural support pylons (140), means for deploying said one or more structural support pylons (138, 141), and one or more therapeutic substances. Structural support pylons (20) may comprise an elastomeric core (22), or may comprise one or more suitable metals, and may be deployed by shortening the length and increasing the height of the pylon. Alternatively, scaffold (200) may comprise a delivery configuration in which first unit (202) and second unit (204) he generally end to end, and a deployed configuration in which superior surfaces (216) and (218) exert an upward force and inferior surfaces (220) and (222) exert a downward force on superior and inferior vertebral surfaces respectively. A method according to the invention may comprise accessing an interior of a diseased or injured bone in a minimally invasive manner, creating a semi-circular path within said bone, deploying one or more structural support pylons within said interior, introducing structural reinforcement material, and if desired, repeating with one or more subsequent structural support pylons.
