Abstract
Methods of reinforcing annulus fibrosis tissue within an intervertebral disc include the implantation of a support member also functioning as a barrier to resist damage to the tissue or herniation of tissue outside the disc. The device may be anchored to the surrounding tissue. The device is compressible and may be delivered in a minimally invasive manner through a cannula.
Claims12
A method of reinforcing an annulus of an intervertebral disc comprising:
- providing a biocompatible support member, wherein said biocompatible support member is a plate-shaped;
- displacing a herniated annulus segment to approximately its pre-herniated location;
- implanting at least a portion of the plate-shaped biocompatible support member along or within the annulus;
- placing said biocompatible support member to substantially close a defect in the annulus;
- and
- positioning said biocompatible support member within the disc such that said biocompatible support member is entirely disposed along the innermost surface of the annulus.

A method of reinforcing a herniated segment of an annulus of an intervertebral disc comprising:
- providing a biocompatible support member, wherein said biocompatible support member is plate-shaped;
- implanting at least a portion of the biocompatible support member along an annulus lamella surface, wherein at least a portion of said biocompatible support member contacts at least a portion of the herniated segment of the annulus;
- securely establishing said plate-shaped biocompatible support member to, within, or posterior to the herniated segment;
- returning at least a portion of the herniated segment of the annulus to a site substantially within its pre-herniated borders;
- and
- positioning said biocompatible support member within the disc such that said biocompatible support member is entirely disposed along the innermost surface of the annulus.
