Abstract
A system for stabilizing a bone structure. The system includes a guide device and an overlying delivery tube. A distal portion of the guide device is positionable within the bone structure and operable in a straight configuration and a curved configuration relative to a longitudinal axis. The overlying delivery tube comprises flexible polymeric material. The flexible polymeric material facilitates the delivery tube assuming a curve within the bone structure relative to the longitudinal axis when the guide device is in the curved configuration. The flexible polymeric material maintains a patent lumen along the curve when the guide device is withdrawn. The system may include an access cannula configured to penetrate the bone structure, and/or an expandable member insertable through the patent lumen along the curve. A delivery device may deliver curable material through the patent lumen along the curve to a target site within the bone structure.
