Semi-biological intervertebral disc replacement system
View Patent ↗The present invention is a system for a partially biological disc replacement that stimulates natural fibrous, cartilaginous or other tissue growth in the DDD cavity, resulting in a partial biological disc replacement. Multiplicities of fibronous pieces of fibro-cartilaginous tissue promoting material are inserted into the DDD cavity inducing tissue growth.
1. A system for semi-biologic nuclear replacement for a degenerated disc of a spine of a mammalian body comprising:
an injection tube having a small diameter corresponding to a small entrance hole defined in the degenerated disc that is at least partially excavated to create a cavity;
a volume of strands of tissue promoting material combined with hydrogel strands sufficient to fill at least a portion of the cavity; and
an insertion device operably coupled to the injection tube that dispenses the volume of strands of tissue promoting material combined with strands of hydrogel into the cavity in a piecemeal manner as a plurality of aliquots of the tissue promoting material and hydrogel strands.
2. The nuclear replacement of claim 1 wherein the tissue promoting material is selected from a group consisting of fibrous tissue promoting material, cartilaginous promoting material and any combination thereof.
3. The nuclear replacement of claim 1 wherein the tissue promoting material is a preparation of multilayered bands piled in a circular configuration.
4. The nuclear replacement of claim 1 wherein the tissue promoting material is a preparation of tangled knots.
5. The nuclear replacement of claim 1 wherein the tissue promoting material is a preparation of multiple fabric bands.
6. The nuclear replacement of claim 1 wherein the tissue promoting material is surrounded by a porous container.
7. The nuclear replacement of claim 1 wherein the tissue promoting material is selected from a group comprising: autograft, allograft, or xenograft of fascia, autograft, manmade polymeric fiber, talc, tissue promoting pharmaceuticals, tissue promoting minerals, tissue morphogenic protein, notochord cells and any combination thereof.
