Abstract
Abstract Reinforcement of annulus fibrosis tissue within an intervertebral disc can be achieved through implantation of a support member also functioning as a barrier to resist damage to the tissue or herniation of tissue outside of 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.

1 . An implant for reinforcing an annulus of an intervertebral disc, comprising a thin resilient barrier having a first surface for placement against an interior surface of an annulus lamella and a second opposing surface, wherein said barrier is adapted to be sealably positioned against the lamella via the exertion of force on at least a portion of the second surface sustained by a pressurized intervertebral disc environment.
Claim 2
Dependent Claim
69 words
1 . An implant for reinforcing an annulus of an intervertebral disc, comprising a thin resilient barrier having a first surface for placement against an interior surface of an annulus lamella and a second opposing surface, wherein said barrier is adapted to be sealably positioned against the lamella via the exertion of force on at least a portion of the second surface sustained by a pressurized intervertebral disc environment.
