Abstract
A catheter device that includes a double-threaded guidance wire that allows multiple use of a compliant cavity creation device (i.e., treatment of more than one level). The double-threaded guidance wire may be connected with the luer part of the device and a distal part of the balloon using a threaded engagement to avoid lengthening of the inner tube, avoid lengthening of the balloon, and to limit the plastic deformation of the system in axial direction. In other implementations, the double-threaded guidance wire may be reconnected to the distal part of the balloon with a distal thread of the double-threaded guidance wire in order to restore the nominal length.
