Abstract:
1. A method for replacing a nucleus pulposus of an intervertebral disk with an implant after a nucleotomy, the nucleotomy providing a nuclear space in the intervertebral disk between a vertebral endplate of an upper vertebra and a vertebral endplate of a lower vertebra, and a boring channel extending through either of the vertebral endplates, the boring channel having a distal end with an opening located adjacent to a vertical axis of the vertebra, the method comprising: inserting the implant comprising a continuous wire through the boring channel and into the nuclear space, further inserting the wire through the boring channel and into the nuclear space, so that the wire continues to coil inside the nuclear space to form a stacked first inner coil inside the outer coil the first inner coil being wound in a direction along the winding axis that is opposite from the direction in which the outer coil is wound,
