Tissue graft material and method of making
View Patent ↗The present invention relates to a method of making a tissue graft material. The method includes placing body tissue and a blood component in a chamber and extruding the body tissue and blood component from an opening in the chamber to form the tissue graft material.
1. A method of making a tissue graft material comprising:
obtaining a blood component by separating the blood component from blood;
placing body tissue and the blood component in a chamber;
extruding the body tissue and blood component from an opening in the chamber to form the tissue graft material; and
implanting the tissue graft material into a patient.
2. The method of claim 1 wherein the blood component is separated by centrifugation of the blood.
3. The method of claim 1 wherein the blood component is autogenic.
4. The method of claim 1 wherein the body tissue is bone.
5. The method of claim 4 wherein the bone is allogenic.
6. The method of claim 1 wherein extruding the body tissue and blood component includes extruding the body tissue and blood component through the opening in a desired shape.
7. The method of claim 6 wherein extruding the body tissue and blood component in a desired shape includes pushing the body tissue and blood component through the opening using a ram.
8. The method of claim 7 wherein pushing the body tissue and blood component with a ram includes increasing the density of the body tissue and blood component.
9. The method of claim 1 further including placing an additional material in the chamber, wherein the additional material is selected from the group consisting of an antibiotic, an apatite, a growth enhancer, gelatin, a polysaccharide, synthetic bone material, a polymer, and a combination thereof.
10. The method of claim 1 wherein allograft material is placed in the chamber with the body tissue and blood component.
11. The method of claim 10 wherein the allograft material, body tissue, and blood component are extruded from the opening in the chamber.
12. The method of claim 11 wherein the blood component is separated by centrifugation of the blood.
13. The method of claim 11 wherein the blood component is autogenic.
14. The method of claim 11 wherein the body tissue, blood component, and allograft material are extruded through the opening in a desired shape.
15. The method of claim 14 wherein the body tissue, blood component, and allograft material are pushed through the opening using a ram.
16. The method of claim 11 further including placing an additional material in the chamber, wherein the additional material is selected from the group consisting of an antibiotic, an apatite, a growth enhancer, gelatin, a polysaccharide, synthetic bone material, a polymer, and a combination thereof.
