Abstract
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.
Claims7
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.
