<p>Therapeutics and methods of treatment to repair, preserve and grow cartilage are presented. In addition, systems and methods for delivering a therapeutic to a hard to reach anatomical area, such as, for example, the BCI, are presented. A cannulated delivery device provided with a cutting tip, cutting flutes and threads on its distal end can be provided. Using such an exemplary device, various novel therapies for joint and cartilage repair, preservation and generation can be implemented. Alternatively, for disc repair, a delivery device directed to percutaneous intradiscal annular repair, or "PIARES" device can be used to introduce therapeutics intradiscally. The device may have two-needles, with a first cannula/needle, with a finger grip at its distal end, and a longer inner needle to penetrate through the outer needle into the disc, and introduce therapeutics, for example, via a syringe. When provided with a septum at the inner needle's proximal end, the PIARES device is a completely closed system, and its use minimizes trauma.</p> |
