Abstract
Methods and devices are described for occluding openings in an annulus fibrosis to prevent conditions such as disc herniation and recurrent disc herniation. An occluding device having an intradiscal component, an extradiscal component, and a barrier element disposed between the intradiscal and extradiscal components is provided. The intradiscal component has first and second arms having a collapsed state with a horizontal dimension less than the width of the opening and an expanded state having a horizontal dimension greater than the width of the opening. The barrier element and the intradiscal component in the collapsed state are inserted through the annulus fibrosis opening, the extradiscal component being positioned adjacent an outer surface of the annulus fibrosis. The intradiscal component assumes the expanded state in the intradiscal space, the first and second arms urging the barrier element against the inner wall of the annulus fibrosis adjacent the opening, thereby occluding the opening.
