Abstract:
1. A method for stabilizing a bone structure of a patient, the method comprising steps of: identifying a target site for locating an expandable member within a bone structure at a predetermined location, directing a distal end of a generally straight access cannula into the bone structure near the target site; providing a guide stylet assembly that comprises directing the stylet and overlying delivery tube simultaneously and coaxially through the access cannula and out the distal end of the access cannula, where the pre-set stylet curved portion, no longer constrained by the access cannula, curves toward and forms a path into the target site as it is extended out of the access cannula distal end; withdrawing the stylet from the overlying delivery tube; then, directing an expandable member in a contracted state through the delivery tube into the target site where the delivery tube provides effective protection for the expandable member from damaging contact with the bone structure; expanding the expandable member to form a cavity at the target site; and, thereafter, delivering a curable material into the cavity.
