Abstract

The present invention is directed to methods for collecting and processing autografts, processed autografts, kits for collecting and transporting autografts, and tools for preparing autografts. It is also directed to autologous bone grafts, and methods of preparing them.

First claim

The invention claimed is:

1. A method of preparing a clean, disinfected autologous tissue implant for implantation, the method comprising:
a) shipping surgically removed autologous tissue collected from a patient to a tissue processing facility;
b) receiving the collected autologous tissue at the tissue processing facility;
c) processing the shipped autologous tissue to clean and disinfect the autologous tissue, wherein the processing comprises treating the autologous tissue with a detergent;
d) storing the processed autologous tissue at a storage facility; and
e) providing the clean, disinfected autologous tissue, including a tracking device, to a surgical facility for re-implantation into the patient,
wherein the autologous tissue is cranial bone, facial bone, a bone of the extremities, a soft tissue, or a periprosthetic bone.

2. The method of claim 1 , wherein the tracking device comprises a microchip.

3. The method of claim 1 , wherein the tracking device comprises a thumb drive.

4. The method of claim 1 , wherein the autologous tissue is cranial bone.

5. The method of claim 4 , wherein the tracking device comprises a microchip.

6. The method of claim 4 , wherein the tracking device comprises a thumb drive.

7. The method of claim 1 , wherein the facial bone is mandible bone, frontal bone, parietal bone, sphenoid bone, temporal bone or nasal bone.

8. The method of claim 1 , wherein the bone of the extremities is a bone of the hand, a bone of the foot, a bone of the arm, or a bone of the leg.

9. The method of claim 8 , wherein the bone of the leg is a tibial bone or a femoral bone.

10. The method of claim 1 , wherein the soft tissue is at least one of a ligament, a tendon, a fascia, or a muscle.

11. The method of claim 1 , wherein the storing the processed autologous tissue comprises including the tracking device.

12. The method of claim 1 , further comprising pre-treating the collected autologous tissue prior to shipping the tissue to a tissue processing facility.

13. The method of claim 12 , wherein the pre-treating comprises treating the collected autologous tissue with an antibiotic solution, a bactericidal solution, a virucidal, a glycerol-containing solution, water, saline or a combination thereof.

14. The method of claim 1 , wherein the processing comprises debridement.

15. The method of claim 1 , wherein the processing comprises treating the autologous tissue with a plasticizer.

16. The method of claim 1 , wherein the processing comprises exposing the autologous tissue to at least one bioactive factor.

17. The method of claim 1 , wherein the autologous tissue is sterilized using irradiation after processing.

18. The method of claim 17 , wherein the tracking device comprises a microchip.

19. The method of claim 1 , further comprising storing the processed autologous tissue in a storage solution, wherein the autologous tissue is irradiated while in the storage solution.

20. The method of claim 19 , wherein the tracking device comprises a microchip.
