  • Publication number: 20110098628
    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 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, 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.

    Abstract: The present invention provides fluid and material delivery methods and devices for practicing the methods. The invention provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection. The method comprises the steps of aspirating the cellular material into a fluid delivery device which incorporates a syringe arrangement. The cellular material is aspirated into the main body of the syringe until the desired amount of a material has filled the syringe body. The needle of the fluid delivery device is then inserted into the skin of a subject at an angle about parallel to the skin until a desired depth has been reached. The cellular material is then injected in the subject until the desired volume of material has been injected. The needle of the device is then rotated approximately 45 to 90 degrees and the needle is removed from the injection site.
