Angulated rings and bonded foils for use with balloons for fusion and dynamic stabilization

摘要

An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.

主权项

1. A method of angling a single-volume balloon to create a multi-volume balloon, the method comprising:
inserting a single-volume balloon into at least one ring, wherein the ring has a first end portion that defines a first opening, a second end portion that defines a second opening, and a central axis that extends through the first and second openings, wherein the first and second end portions are disposed at an oblique angle with respect to the central axis to define a predetermined angle of the end portions of the at least one ring; inserting the ring containing the single-volume balloon into a cavity of a vertebral column, wherein the cavity is selected from the group consisting of an intervertebral disc space and a space in a vertebral body; and expanding the single-volume balloon, wherein the expansion of the single-volume balloon within the ring forms a multi-volume balloon having at least two compartments, with the predetermined angle of the ring determining the angulation of a longitudinal axis of each compartment of the multi-volume balloon with respect to the central axis.
