| 1. A method for treating a diseased or damaged intervertebral spinal disc having an inner nucleus pulposus and an outer annulus,
comprising the steps of:
providing access to the nucleus pulposus through the annulus;
removing at least a portion of said nucleus pulposus to create an intradiscal space;
determining the integrity of said annulus by sealably injecting a fluid under pressure directly into the intradiscal space;
and then
sealably introducing under pressure a curable biomaterial, different from said fluid under pressure, through said annulus
access directly into said intradiscal space.
