The Osseoflex SN+ steerable needle enables direct access to the entire vertebral body by way of a unipedicular approach for percutaneous vertebral augmentation. The Osseoflex SN+ 8 gauge steerable, articulating needle is used either individually or in combination with the Osseoflex SB 8 gauge steerable balloon for cavity creation. Cavity creation is achieved through the disruption of bone by steering and channeling with the Osseoflex SN+ or by inserting the Osseoflex SB steerable balloon for void creation.
