Abstract

An inflatable balloon for diagnostics and treatment of diseased discs or fractured bones. The balloon is a multi-volume balloon comprised of a plurality of adjustable and expandable single volumes. Further disclosed are methods of forming, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the diseased discs or fractured bones. Still further disclosed are kits for aligning and stabilizing a bone, disc, or spinal motion segment.

First claim

What is claimed:

1. A multi-volume balloon for treating the clinical consequences of degenerative disc disease, vertebral body bone defects, and spinal motion segment instability comprising:
a plurality of single volumes each connected, directly or indirectly, to one another,
a fill tube configured to be inserted through the plurality of single volumes,
a perforated guide tube contained within the multi-volume balloon and extending through each of the single-volumes,
wherein each single volume is individually and independently adjustable and expandable and configured to maintain said individual and independent adjustment and expansion after the fill tube is removed therefrom, such that
(a) each single volume can contain a variable volume of contents, and
(b) each of the plurality of single volumes can contain the same, or a different, amount and type of contents relative to another single volume.

2. The multi-volume balloon according to claim 1 , wherein
the fill tube is adapted to be inserted into the perforated guide tube,
wherein the fill tube is capable of delivering contents to the plurality of single volumes and the amount of contents delivered to the plurality of single volumes is adjustable and variable in each volume; and
a delivery tube is attached to the fill tube, wherein the delivery tube is adapted to be connectable to the perforated guide tube.

3. The multi-volume balloon according to claim 2 , wherein the single volumes are connected via the perforated guide tube to form the multi-volume balloon.

4. The multi-volume balloon according to claim 2 , wherein the perforated guide tube is flexible and pre-shaped into a curved formation.

5. The multi-volume balloon according to claim 1 further comprising a ring configured to create a seal between two connected and expanded single volumes, wherein the two single volumes are connected via a puncture in a first single volume that contains a section of the second single volume and secured by the ring connecting the first and second single volumes to form the multi-volume balloon.

6. The multi-volume balloon according to claim 5 further comprising: a third single volume connected to the second single volume of the multi-volume balloon via a puncture in the second single volume of the multi-volume balloon and secured by a second ring connecting the second single volume and the third single volume to form the multi-volume balloon comprising three single volumes.

7. The multi-volume balloon according to claim 5 wherein the ring is a one-way valve.

8. The multi-volume balloon according to claim 1 , wherein each of the single volumes is external to the other single volumes.

9. The multi-volume balloon according to claim 1 , further comprising rigid contents.

10. The multi-volume balloon according to claim 9 , wherein the rigid contents include bone cement.

11. The multi-volume balloon according to claim 1 , wherein the fill tube is configured to extend through an entire length of at least one of the single volumes.

12. The multi-volume balloon according to claim 1 , wherein the volume of contents in a first single volume is not limited by the volume of contents in a second single volume.

13. A kit for aligning and stabilizing a bone, the kit comprising:
a multi-volume balloon including a plurality of adjustable single-volume balloons each connected, directly or indirectly, to one another;
a perforated guide tube contained within the multi-volume balloon and extending through each of the single-volume balloons;
a fill tube adapted to be inserted into the perforated guide tube and capable of delivering contents to the plurality of single-volume balloons; and
a delivery tube adapted to be connected both to the fill tube and to the perforated guide tube,
wherein each single-volume balloon is individually and independently adjustable and expandable and configured to maintain said independent adjustment and expansion after the fill tube is removed therefrom, such that
(a) each single-volume balloon can contain a variable volume of contents, and
(b) each of the plurality of single-volume balloons can contain the same, or a different, volume of contents relative to another single-volume balloon.

14. The kit according to claim 13 , wherein each of the single-volume balloons is external to the other single-volume balloons.

15. The kit according to claim 13 , further comprising rigid contents.

16. The kit according to claim 15 , wherein the rigid contents include bone cement.

17. The kit according to claim 13 , wherein the fill tube extends through an entire length of at least one of the single-volume balloons.

18. The kit according to claim 13 , wherein the volume of contents in a first single-volume balloon is not limited by the volume of contents in a second single-volume balloon.
