A method for treating a diseased or damaged spinal disc comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the size of the intradiscal space; and sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The clam type electronic device includes a first case, a second case and the vacuum latch structure. The second piece of material forms a second pair of sidewalls.
