## Abstract

Red light-emitting implants for treating degenerative disc disease.

## Claims

### Claim 1

A method of treating a degenerating disc comprising a nucleus pulposus and an annulus fibrosus, comprising the steps of:
a) implanting into a vertebral body an implant comprising a red light source and an emission surface,
b) powering the red light source to transmit red light from the red light source through the emission surface and the vertebral endplate to the intervertebral disc.

### Claim 2 (depends on 1)

The method of claim 1 further comprising the step of:
c) orienting the implant so that the emission surface faces the vertebral endplate.

### Claim 3 (depends on 2)

The method of claim 2 wherein the emission surface faces a center of the vertebral endplate.
