Disclosed herein are methods for treating a defect in a spinal disc nuclear space, comprising: (a) creating an opening by open, percutaneous or laparoscopic techniques to access the defect in the nuclear space; (b) removing a desired amount of tissue from the nuclear space; (c) positioning a delivery catheter through the opening; (d) fluidically isolating the nuclear space by blocking the opening with a blocking component of the catheter; (e) delivering an in-situ curable liquid material through a lumen of the catheter to the nuclear space; and (f) maintaining the isolating until the liquid material has cured. Also disclosed are treatment systems and materials for prostheses.

Disc annulus closure

Surgical methods of repairing defects and deficiencies in the spine are disclosed. The methods involve delivering a single part in-situ polymerizing fluid to (i) close a weakened segment or fissure in the annulus fibrosus, (ii) strengthen the annulus, (iii) replace or augment the disc nucleus, or (iv) localize a disc prosthesis. The methods may include placing a delivery conduit adjacent to the repair site and providing a liquid tissue adhesive to bond to and repair a disc defect or deficiency.

Devices and methods for spine repair

The present invention relates to a devices and methods for killing and/or debilitating pathogenic microorganisms in or on a patient's body, such as light-sensitive bacteria includingand/or. A chemiluminescent light source provides electromagnetic radiation having predetermined wavelengths in the visible spectrum. The light wavelengths are selected for absorption by naturally-occurring photosensitive chemicals produced by the patient's body.
