Cord for vertebral stabilization system

A spinal stabilization system including a cord extendable between first, second and third vertebral anchors. A first length of the cord includes a first set of intermingled filaments, and a second length of the cord includes a second set of intermingled filaments. The first set of intermingled filaments includes a first subset of filaments and a second subset of filaments, and the second set of intermingled filaments includes the first subset of filaments of the first set of intermingled filaments and a third subset of filaments different from the second subset of filaments of the first set of intermingled filaments. When secured to the first, second and third vertebral anchors, a first portion of the cord may be tensioned a first amount and a second portion of the cord may be tensioned a second amount different from the first amount.
