Systems and methods for vertebral or other bone structure height restoration and stabilization

The invention provides a method for stabilizing a vertebral body of a patient, the method comprising: directing an expandable member in a contracted state to a first target site within the vertebral body accessed through a first pedicle of the vertebral body; transitioning the expandable member from a contracted state to an expanded state within the vertebral body, thereby forming a cavity; delivering a curable material to a second target site within the bone structure accessed through a second pedicle of the vertebral body while the expandable member remains in the expanded state within the vertebral body at the first target site; transitioning the expandable member from the expanded state to the contracted state; and removing the expandable member from the vertebral body.
