Abstract:
1. A method for stabilizing a bone structure, the method comprising: directing an access cannula, with a longitudinal axis, into a bone structure; directing a polymer delivery tube through an access site into the bone structure, where the delivery tube extends through and beyond a distal end of the access cannula to a first target region, forming a tubular cavity along a delivery tube length within the bone structure; retracting longitudinally the delivery tube from a distal portion of the tubular cavity; directing an expandable member to, and then expanding the expandable member in, the distal portion of the tubular cavity to form a first cavity having a larger diameter than the tubular cavity; deflating, then retracting longitudinally the expandable member and the delivery tube to a desired location in the tubular cavity which location is nearer than the location of the first cavity to the access site; expanding again the expandable member in the desired location of the tubular cavity, to form a second cavity with a larger diameter than the tubular cavity and disposed between the first cavity and the access site; and filling at least a portion of the first cavity and the second cavity with a curable material.
