| titleOfInvention | Disc shunts for back pain |
| abstract | The intervertebral disc is avascular. Nutrients and waste are diffused through adjacent vertebral bodies into the disc. As we age, calcified layers form between the disc and vertebral bodies, blocking diffusion of nutrients, oxygen and pH buffer in blood. Under anaerobic conditions, lactic 5 acid is produced, irritating nerve endings and causing nonspecific pain. In addition, the disc begins to starve and flatten. The weight shifts abnormally from disc to the facet joints causing strain and back pain. Shunt coils are formed and spiraled over the distal shaft of a twistable needle, then deployed into the nucleus of a degenerated disc by a sliding sleeve. The coils serve as an internal shunt, 10 drawing nutrients, oxygen and buffering solute from the superior and inferior diffusion zones to neutralize lactic acid in the mid layer of the degenerated disc. The coils also serve as a bulking agent within the repaired disc to sustain compression and reduce facet loading and segmental instability. The end strands of the shunt coils can also extend from the disc to draw blood plasma from muscle or bodily circulation to expedite neutralization of lactic acid and rebuild disc matrix 15 for pain relief and disc regeneration. |
