Abstract:
A segmented intervertebral body fusion support includes a plurality of segments, the segments including an initial segment, a final segment and at least one intermediate segment. The intermediate segment has a generally trapezoidal configuration and the initial and final segments include tapered side walls providing triangular gaps between adjacent segments. A draw wire is fixed to the first segment and passes through the remaining segments. By pulling the draw wire relative to the segments, the segments are drawn together in a generally arcuate configuration. The draw wire includes an enlargement that passes through the final segment and engages a plurality of fingers on the final segment, which prevents the draw wire from retracting, maintaining the arcuate configuration. The segmented device can be inserted through a laparoscopic device into the intervertebral space and can be subsequently drawn into the arcuate configuration to establish the desired intervertebral spacing.
