Abstract
Abstract A pliable band or hoop that is flexible to normal handling, but cannot stretch circumferentially once it has reached the limits of its circumferential length. The band may have a structural portal to be used for filling, or it may simply be constructed of a fabric-like material that allows a fill tube to perforate its walls to allow for filling. In the latter case, the perforated wall tends to self-seal once the fill tube is withdrawn. The band may be flat or tubular in cross-section. However, unlike a balloon, the band does not require either a bottom or a top, as we found that a top and bottom are unnecessary when using a band or hoop to enclose material injected into a reamed out intervertebral space.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
143 words
A device for stabilizing a spinal motion segment comprising: a substantially tubular member constructed from a generally pliable, but minimally elastic material, the substantially tubular member having a first end and a second end, the substantially tubular member defining an interior space and an opening at the first end and the second end, the substantially tubular member having a circumference sized to fit in the immediate vicinity of the outer annulus of the intervertebral disc of a mammalian spine, the substantially tubular member having a central axis, the central axis extending between the first end and the second end, the central axis constructed and arranged to be generally collinear with a cephalo-caudal axis of the mammalian spine when fitted into the immediate vicinity of the outer annulus of the intervertebral disc, the substantially tubular member having a predetermined height and a predetermined thickness.
Claim 2
Independent Claim
143 words
A device for stabilizing a spinal motion segment comprising: a substantially tubular member constructed from a generally pliable, but minimally elastic material, the substantially tubular member having a first end and a second end, the substantially tubular member defining an interior space and an opening at the first end and the second end, the substantially tubular member having a circumference sized to fit in the immediate vicinity of the outer annulus of the intervertebral disc of a mammalian spine, the substantially tubular member having a central axis, the central axis extending between the first end and the second end, the central axis constructed and arranged to be generally collinear with a cephalo-caudal axis of the mammalian spine when fitted into the immediate vicinity of the outer annulus of the intervertebral disc, the substantially tubular member having a predetermined height and a predetermined thickness.
Claim 3
Dependent Claim
26 words
The device of claim 1 wherein the predetermined height of the substantially tubular member, measured along the central axis, is between 0.25 mm and 20 mm.
Claim 4
Dependent Claim
21 words
The device of claim 1 wherein the predetermined thickness of the substantially tubular member is between 0.01 mm and 5 mm.
Claim 5
Dependent Claim
