ABSTRACT:
A method for retaining an intra-discal material within an annulus fibrosis is described. The annulus fibrosis has a posterior annulus, an inside surface, and an opening with a lateral and a vertical dimension. A single wire and a band is provided. The single wire is made of shape-memory material and has a first compressed configuration and a second expanded configuration. The band and the single wire, which is in the first compressed configuration, is inserted through the opening in the annulus fibrosis. After insertion through the opening, the single wire expands to the second expanded configuration. The single wire and the band are positioned near the posterior annulus to rest against annulus fibrosis tissues adjacent the opening on the inside surface of the annulus fibrosis, such that the band is positioned to rest against annulus fibrosis tissues adjacent the opening, thereby preventing escape of intra-discal material through the opening.
