    摘要： The intervertebral disc is avascular. With aging, endplates become occluded by calcified layers, and diffusion of nutrients and oxygen into the disc diminishes. The disc degenerates, and pain ensues. Conduits are delivered and deployed into the intervertebral disc to reestablish the exchange of nutrients and waste between the disc and bodily circulation to stop or reverse disc degeneration and relieve pain. The intervertebral disc installed with semi-permeable conduits may be used as an immuno-isolated capsule to encapsulate donor cells capable of biosynthesizing therapeutic molecules. The semi-permeable conduits establish the exchange of nutrients and therapeutic molecules between disc and bodily circulation to treat a disease without using immunosuppressive drugs.

    摘要： An elastically curved suture anchor is resiliently straightened and delivered into tissue by a needle. When the needle is withdrawn, resumption of the curvature provides leverage for anchor rotation as the attached suture is pulled to fasten the anchor within the tissue. A fin at the proximal end of the anchor further increases the rotational leverage and expedites anchor fastening. When two or more anchors with connecting suture are delivered in series on a needle, the tension of the suture helps to draw the anchors together and approximates the pierced tissue.

    摘要： A solid stepped needle delivers a disc shunt bridging between muscle and a degenerated disc, drawing blood plasma from muscle into the degenerated disc to alleviate back pain and regenerate the disc. The device further includes pull lines attached to the ends of the disc shunt for withdrawing and repositioning the stepped needle during shunt delivery.

    摘要： The intervertebral disc contains no blood vessels. Nutrients and waste are diffused mainly through adjacent vertebral bodies. As we age, calcified layers form between the disc and vertebral bodies, blocking diffusion. The disc begins to starve and flatten. The weight shifts abnormally from disc to the facet joints causing strain and back pain. Under anaerobic conditions, lactic acid is produced causing acidic irritation and unspecific pain. A U-shaped disc shunt is delivered into and sealed within the degenerated disc simply by needle puncturing and withdrawal, to draw nutrients from bodily circulation into the avascular disc. A continual supply of nutrients increases biosynthesis of the water-retaining sulfated glycosaminoglycans, hence swelling pressure within the disc. The weight is re-shifted from the facet joints to the regenerated disc, alleviating back pain. With oxygen transported through the shunt, anaerobic production of lactic acid is minimized. In addition, the residual lactic acid is expelled through the U-shaped shunt during disc compression into bodily circulation to alleviate unspecific pain.

    摘要翻译： 椎间盘不含血管。 营养物和废物主要通过相邻的椎体扩散。 随着年龄的增长，钙化层形成在椎间盘和椎体之间，阻止扩散。 光盘开始变得饿死了。 重量从椎间盘异常移动到小关节，引起应变和背部疼痛。 在厌氧条件下，产生乳酸，引起酸性刺激和非特异性疼痛。 U形盘分流器简单地通过针穿刺和抽出而被输送并退化在退化的椎间盘中，以将营养物从身体循环中吸收到无血管盘中。 持续供应营养物质可增加保水性硫酸糖胺聚糖的生物合成，从而增加盘内的压力。 重量从小关节重新转移到再生椎间盘，减轻背痛。 通过分流运送的氧气，乳酸的厌氧生产被最小化。 另外，残留的乳酸通过U形分流在椎间盘压迫期间被排出到身体循环中以减轻非特异性疼痛。
