Abstract

Disclosed herein are devices for minimally invasive vertebral augmentation and restoration of spinal lordosis using a steerable cannula assembly. When deployed, the articulating cannula, including an outer cannula and an inner cannula extending into a central lumen of the outer cannula and coupled to each other at their distal ends, can be manipulated to curve/bend the body of the articulating cannula. This manipulation is used to create a void within the interior body and may also be used to control delivery of a treatment element to the interior body.
