摘要： A regeneration device and method for sealing annular tears between the nucleus pulposus and the annulus fibrosus of an intervertebral disc. The regeneration device includes a trocar having a sharp tip at a distal end, an inner cavity, and a handle portion attached to a proximal end of the trocar. The device further includes a plunger coupled to a catheter that extends through the inner cavity. The regeneration method includes inserting the trocar into an intervertebral disc via Kambin's triangle, and once the trocar reaches the nucleus pulposus, the catheter is extended alongside the annulus fibrosus wall to surround the nucleus pulposus. A syringe is mounted to the plunger and injects a biochemical, biological and/or synthetic material through multiple ports in the catheter to form a collagen barrier that prevents the nucleus pulposus from protruding through the annulus fibrosus.
