SYSTEMS AND METHODS FOR VERTEBRAL OR OTHER BONE STRUCTURE HEIGHT RESTORATION AND STABILIZATION
First Claim
1. A method for stabilizing a bone structure of a patient, the method comprising:
- directing a first expandable member in a contracted state to a first location within the bone structure;
directing a second expandable member in a contracted state to a second location within the bone structure, the second location being spaced from the first location;
transitioning the first expandable member to an expanded state that forms a first cavity within the bone structure;
transitioning the second expandable member to an expanded state that forms a second cavity within the bone structure;
transitioning the first expandable member from the expanded state to the contracted state while maintaining the second expandable member in the expanded state;
removing the first expandable member from the bone structure;
delivering a curable material into the first cavity;
transitioning the second expandable member from the expanded state to the contracted state;
removing the second expandable member from the bone structure; and
delivering a curable material into the second cavity.

Abstract
A method for stabilizing a bone structure including directing first and second expandable members in contracted state to a first location within the bone structure. The expandable members are expanded, forming first and second cavities within the bone structure. The first expandable member is then transitioned back to the contracted state while maintaining the second expandable member in the expanded state. The first expandable member is removed, and curable material delivered into the first cavity. The second expandable structure is contracted and removed. A curable material is delivered into the second cavity. A height of the bone structure is restored via expansion of the two expandable members, and is retained throughout the procedure first by the second expandable member during delivery of curable material into the first cavity, and then by the hardened material in the first cavity during removal of the second expandable member.

14. A method for stabilizing a vertebral body of a patient, the method comprising:
-
a) directing a first expandable member in a contracted state to a first location within the vertebral body; b) directing a second expandable member in a contracted state to a second location within the vertebral body, the second location being spaced from the first location; c) transitioning the first expandable member to an expanded state that forms a first cavity within the vertebral body; d) transitioning the second expandable member to an expanded state that forms a second cavity within the vertebral body; e) transitioning the first expandable member from the expanded state to the contracted state while maintaining the second expandable member in the expanded state; f) removing the first expandable member from the vertebral body; g) delivering a curable material into the first cavity; transitioning the second expandable member from the expanded state to the contracted state; removing the second expandable member from the vertebral body; and delivering a curable material into the second cavity - View Dependent Claims (15)
