  • Cord for Vertebral Fixation Having Multiple Stiffness Phases
    Publication number: 20150238231
    Abstract: A dynamic stabilization system for stabilizing a vertebral segment of a spine. The system includes a first vertebral anchor, a second vertebral anchor and a cord. The system may also include a spacer positioned between the first and second vertebral anchor through which the cord extends. The first vertebral anchor is configured to be secured to a first vertebra and the second vertebral anchor is configured to be secured to a second vertebra. The cord is extendable from the first vertebral anchor to the second vertebral anchor. The cord has a variable stiffness through a range of displacement, wherein the stiffness of the cord increases as an applied tensile force on the cord is increased.

  • Cord for vertebral stabilization system
    Patent number: 8328849
    Abstract: 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.
