CORD FOR VERTEBRAL STABILIZATION SYSTEM

摘要

A spinal stabilization system (10) including a cord (30) extendable between first (12a), second (12b) and third (12c) vertebral anchors. A first length (LI) of the cord includes a first set of intermingled filaments (33), and a second length (L2) of the cord includes a second set of intermingled filaments (33). The first set of intermingled filaments includes a first subset of filaments (33a) and a second subset of filaments (33b), and the second set of intermingled filaments includes the first subset of filaments (33a) of the first set of intermingled filaments and a third subset of filaments (33c) 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.
