Methods, systems, and devices for treating intervertebral discs including intradiscal fluid evacuation
Abstract:
Methods, systems, and devices for of treating intervertebral discs are disclosed. In one embodiment, a minimally invasive method of treating an intervertebral disc is provided. A contrast or imaging media is introduced into a nucleus of the intervertebral disc without removing any of the nucleus. The intervertebral disc is imaged with the contrast media within the nucleus. Then the contrast media is evacuated from the nucleus to reduce intradiscal pressure. Finally, a disc augmentation biomaterial is introduced into the nucleus. The disc augmentation biomaterial is introduced in such a manner that the disc augmentation biomaterial is maintained within the nucleus without having to repair an opening in the annulus surrounding the nucleus.
