Processes and systems for loading medical implants with simulative growth agents
View Patent ↗Methods and systems for providing an improved apparatus and packaging system to more expeditiously hydrate or reconstitute medical grafts and to effectively and uniformly seed the medical grafts with biological components and cells. The systems generally comprise a container comprising entry port, at least one substrate cavity, and top, side and bottom walls defining an inner surface. The entry port is configured to receive the biological solution. The cavity is in communication with the entry port and includes the porous substrate maintained under negative pressure. The container volume is substantially the same as a volume of the porous substrate. The side and bottom walls are configured to promote a laminar flow of the biological solution received through the entry port.
1. A system for loading bone morphogenetic material into a medical graft, comprising:
a hermetically sealed container comprising an entry port, a substrate cavity, and top, side and bottom walls defining an inner surface of the container, a lip surrounding a periphery of the substrate cavity and the top wall is hermetically sealed to the lip adjacent the substrate cavity periphery;
the entry port configured to receive the bone morphogenetic material;
the substrate cavity in communication with the entry port and having the medical graft stored and maintained under negative pressure; and
wherein a container volume is substantially the same as a volume of the medical graft.
2. The system of claim 1 , wherein the entry port is disposed near the middle of the medical graft within the substrate cavity.
3. The system of claim 1 , wherein the container further comprises one or more supporting members configured to elevate and support the container in a substantially stable position.
4. The system of claim 1 , wherein said bone morphogenetic material is selected from the group consisting of bone morphogenetic protein (BMP), transforming growth factor β (TGF-β) growth differentiation factor (GDF), and cartilage derived morphogenetic protein (CDMP).
5. The system of claim 4 , wherein said bone morphogenetic protein is selected from the group consisting of BMP-1, BMP-2, BMP-3, BMP-4, BMP-5, BMP-6,BMP-7, BMP-8, BMP-9, BMP-10, and BMP-11.
6. The system of claim 4 , wherein said bone morphogenetic material is a recombinant human bone morphogenetic protein.
7. The system of claim 6 , wherein said recombinant human bone morphogenetic protein is rhBMP-2.
8. The system of claim 1 , wherein said medical graft is a bioabsorbable absorbent matrix.
9. The system of claim 8 , wherein said absorbent matrix comprises a purified collagen matrix.
10. The system of claim 9 , wherein said collagen is selected from the group consisting of Type I collagen, Type II collagen, Type IV collagen, cell-contracted collagen, and combinations thereof.
11. The system of claim 9 , wherein said collagen matrix comprises a nanofiber density of 10 nanofiber per 100 micron 3 collagen matrix volume.
12. A system for loading bone morphogenetic material into a medical graft, comprising:
a hermetically sealed container comprising an entry port configured to receive the bone morphogenetic material, and top, side and bottom walls defining a substrate cavity, a lip surrounding a periphery of the substrate cavity and the top wall is hermetically sealed to the lip adjacent the substrate cavity periphery;
the entry port being disposed near the middle of the medical graft within the substrate cavity,
the substrate cavity in communication with the entry port and having the medical graft stored and maintained under negative pressure; and
wherein a container volume is substantially the same as a volume of the medical graft.
13. The system of claim 12 , wherein the container further comprises one or more supporting members configured to elevate and support the container in a substantially stable position.
14. The system of claim 12 , wherein said bone morphogenetic material is selected from the group consisting of bone morphogenetic protein (BMP), transforming growth factor β (TGF-β), growth differentiation factor (GDF), and cartilage derived morphogenetic protein (CDMP).
15. The system of claim 14 , wherein said bone morphogenetic protein is selected from the group consisting of BMP-1, BMP-2, BMP-3, BMP-4, BMP-5, BMP-6, BMP-7, BMP-8, BMP-9, BMP-10, and BMP-11.
16. The system of claim 14 , wherein said bone morphogenetic material is a recombinant human bone morphogenetic protein.
17. The system of claim 16 , wherein said recombinant human bone morphogenetic protein is rhBMP-2.
18. The system of claim 12 , wherein said medical graft is a bioabsorbable absorbent matrix.
19. The system of claim 18 , wherein said absorbent matrix comprises a purified collagen matrix.
20. The system of claim 19 , wherein said collagen is selected from the group consisting of Type I collagen, Type II collagen, Type IV collagen, cell-contracted collagen, and combinations thereof.
21. The system of claim 19 , wherein said collagen matrix comprises a nanofiber density of 10 nanofiber per 100 micron 3 collagen matrix volume.
