<p>A tissue-fastening device with counter gripping resilient anchors folded within a needle is delivered through bulging tissue into the intervertebral disc. The bulge is then compressed, a plunger is held stationary behind the fastener while the needle is withdrawn. As the restriction of the needle is removed, the resilient anchors open, counter fastening the annular tissues across the central disc by both ends of the tissue fastener. Since the anchors open within the compressed bulge, the previously bulging annulus is mechanically anchored and fastened down by the tissue fastener, free from impinging the adjacent nerve. A toggle and a disc restraining device are also proposed to compress bulging discs. To decompress bulging discs, a disc drain tube containing inlet and outlet openings, with pressure-regulating capabilities, drains nucleus pulposus from a swollen intervertebral disc to alleviate low back pain.</p> |
