Patent ID: 8236057

Claim:
An inflatable balloon device for an intervertebral disc comprising at least three independent, adjacent hollow cylindrical tube chambers, wherein each tube is curved to form a ring and the rings are arranged concentrically around an axis, substantially in a plane perpendicular to the concentric axis; and at least one rotating ball valve adapted to allow a filler material to be inserted at least partially concurrently into at least two of said at least three hollow cylindrical tube chambers by rotating the ball valve to an open position allowing filler material to enter at least two of said chambers, wherein said rotating ball valve is also adapted such that it is capable of stopping material from entering or exiting a chamber when the chamber has reached a desired amount of filling; wherein said inflatable balloon device is adapted to distribute load placed on the inflatable balloon device after filling, approximately evenly across multiple of the at least three hollow cylindrical tube chambers.
