Abstract: A mandrel is inserted into the tissue to be distracted and a filament is repeatedly wrapped around the mandrel to make a spool. As the mandrel turns, the filament coils around the mandrel to create of spool of increasing diameter. This spool can be used as a distractor, tamp, or implant. A spool implant can be cemented to further stabilize the device in situ, such as a vertebral body. The filament deposition upon the mandrel is controlled by rotation and the volume creation is incremental. This makes the spool ideal for creating highly controlled distraction forces or insertion of bulking material. In some embodiments, fibers having a low glass transition temperature are used.

Abstract: Methods and devices are provided for replacing damaged, injured, diseased, or otherwise unhealthy elements of the spinal three-joint complex, such as the facet joints and discs. In one exemplary embodiment, a joint replacement system includes a facet replacement component that is adapted to replace and/or augment the facet joints, and a disc replacement component that is adapted to replace a spinal disc. The facet replacement component and the disc replacement component can couple to one another to allow and/or control flexion, extension, and/or lateral bending of the spine, preferably while substantially restricting posterior-anterior shear and axial rotation of the spine.
