10. The device of claim 5 , wherein the semi-permeable membrane is recognized as self by the subject.
11. The device of claim 1 , wherein the one or more biologically active materials are produced by one or more living cells or tissues.
12. The device of claim 11 , wherein the one or more living cells or tissues are at least partially enclosed by a semi-permeable membrane.
13. The device of claim 12 , wherein the semi-permeable membrane is at least partially surrounded by the porous bone cage.
14. The device of claim 11 , wherein the one or more living cells or tissues are autologous.
15. The device of claim 11 , wherein the one or more living cells or tissues are genetically engineered.
16. The device of claim 11 , wherein the one or more living cells or tissues are non-immunogenic with respect to the subject.
17. The device of claim 1 , wherein the living bone cells are autologous.
18. The device of claim 1 , wherein the living bone cells bind the one or more biologically active materials.
19. The device of claim 1 , wherein the living bone cells are treated to at least partially prevent restructuring in the subject.
20. The device of claim 1 , wherein the living bone cells are treated to enhance restructuring in the subject.
21. The device of claim 1 , wherein the living bone cells are at least partially resorbable.
22. The device of claim 1 , wherein the living bone cells are immunogenic with respect to the subject.
23. The device of claim 1 , wherein the living bone cells are non-immunogenic with respect to the subject.
24. The device of claim 1 , wherein the living bone cells are recognized as self by the subject.
25. The device of claim 1 , wherein the living bone cells are genetically engineered.
26. The device of claim 25 , wherein the living bone cells are genetically engineered to at least partially prevent restructuring.
27. The device of claim 25 , wherein the living bone cells are genetically engineered to enhance restructuring.
28. The device of claim 1 , wherein the subject is an animal.
29. The device of claim 28 , wherein the animal is selected from the group consisting of a domesticated animal, a farm animal, a marine animal, a sport animal, a wild animal, a research animal, a zoo animal, a bird, an amphibian, a reptile, a fish and a mammal.
30. The device of claim 29 , wherein the mammal is a human.
31. The device of claim 1 , wherein the porous bone cage includes a semi-permeable membrane.
32. The device of claim 31 , wherein the semi-permeable membrane is autologous with respect to the subject.
33. The device of claim 31 , wherein the semi-permeable membrane is allogeneic with respect to the subject.
34. The device of claim 31 , wherein the semi-permeable membrane is xenogeneic with respect to the subject.
35. The device of claim 6 , wherein the semi-permeable membrane surrounds the porous bone cage.
36. The device of claim 7 , wherein the semi-permeable membrane surrounds the one or more biologically active materials.
37. The device of claim 11 , wherein the one or more living cells or tissues are enclosed by a semi-permeable membrane.
38. The device of claim 11 , wherein the one or more living cells or tissues are immunogenic with respect to the subject.
39. The device of claim 5 , wherein the semi-permeable membrane includes cells with tight junctions, one or more plasma membranes, one or more intracellular membranes, one or more red blood cell ghosts, and one or more aggregated platelets or other cells.
