Patent ID: 7019192

Claim:
A sterile formable bone composition for application to a bone defect site to promote new bone growth at the site comprising demineralized osteoinductive and osteoconductive bone particles in an aqueous carrier solution, said bone particles are alloaraft bone ranging from about 100 microns to about 850 microns in size at a concentration ranging from 20% to 35% by weight of the composition, the carrier comprising a hydrogel component of sodium hyaluronate or its derivatives in a phosphate buffered aqueous solution, said hydrogel ranging from about 1.0% to about 5.0% by weight of the aqueous carrier solution and cellular material taken from a group consisting of living cells, cell elements such as red blood cells, white blood cells, platelets, blood plasma, pluripotential cells, osteoblasts, osteoclasts, and fibroblasts, epithelial cells, and endothelial cells present at a concentration of 10 5 to 10 8 per cc of the carrier, said hydrogel component having a high molecular weight ranging from about six hundred sixty thousand to three million Daltons with a stable viscosity at a temperature ranging from about 22° C. to about 37° C. and said composition having a pH ranging from about 6.8 to about 7.4
