Patent Images
1. A treatment device for repairing a defect in the intervertebral disc of a living being, said device comprising;
- an elongated instrument, at least one bridging member, and a plurality of connector members;
with said elongated instrument being arranged to be placed in or near the defect, and being further arranged to deliver said at least one bridging member inside of the intervertebral disc at a first location;
wherein said elongated instrument is further arranged to displace said bridging member from said first location to a second location;
wherein said second location comprises at least a portion of the defect;
wherein said connector members are arranged to be deployed from said elongated instrument into tissue at or near the defect and to engage said at least one bridging member such that said bridging member is secured at said second location;
wherein said bridging member serves to provide support to the intervertebral disc, and wherein the treatment comprises said support.

Abstract
A system for repairing a vertebral disc defect, such as hernia or bulge, a full or partial tear in the annulus, or a weakened annulus wall as a result of an excision procedure. The system introduces a treatment device arranged to repair the defect, and may prevent the leakage of fluid from the nucleus. The components of the device may be resorbable materials, and may induce the ingrowth of cellular material into the components. The system may feature a locating device to ensure proper placement of the treatment device.
