The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by varying the hardness of the elastomeric material in its nucleus and annulus.

This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by providing reinforcing fibers of appropriate orientation and number within an elastomeric matrix.

The invention comprises a bio-compatible composition suitable for constructing surgical articles for the repair or replacement of a part of the body of a human or non-human animal, e.g., ligaments, tendons, bones, comprising a composite of a bio-absorbable polymer and at least one substrate of a plurality of carbon fibers. The invention also includes surgical articles fabricated from the composites for the repair of damaged tissue, e.g., tendons, ligaments and bones. The invention includes a method for the formation of the aforesaid composite comprising providing a substrate of the carbon fibers and providing the substrate with a continuous coating of a bio-absorbable polymer. The invention also includes the surgical repair of a damaged body part such as a ligament, tendon or bone comprising surgically affixing to the damaged part the surgical article, the bio-absorbable polymer being absorbed by the body upon formation of the new tissue.
