Systems and methods to affect anatomical structures
Systems and method to affect anatomical structures is disclosed. The systems and method can be used to regenerate bone. The system can comprise a nanofiber mesh configured to substantially conform to an anatomical structure, wherein at least a portion of the nanofiber mesh defines a fillable space. The system can comprise a carrier substance comprising an active agent, such as a bone morphogenetic protein, The carrier substance can be disposed within the fillable space.
1. A system for affecting an anatomical structure having a fillable space, the system comprising
a nanofiber mesh configured to substantially conform to an external surface of the anatomical structure, wherein at least a portion of the nanofiber mesh delineates a boundary between a milieu surrounding the anatomical structure and the fillable space of the anatomical structure and further comprising an injectible, flowable carrier substance substantially filling the fillable space of the anatomical structure.
2. The system for affecting an anatomical structure of claim 1 , further comprising an active agent.
3. The system for affecting an anatomical structure of claim 1 , wherein the nanofiber mesh has an average pore size of less than about 100 micrometers.
4. The system for affecting an anatomical structure of claim 1 , wherein the nanofiber mesh further comprises a plurality of macropores.
5. The system for affecting an anatomical structure of claim 2 , wherein the active agent comprises at least one member of the transforming growth factor beta superfamily.
6. The system for affecting an anatomical structure of claim 5 , wherein the carrier substance comprises a hydrogel.
7. The system for affecting an anatomical structure of claim 6 , wherein the anatomical structure is bone, and wherein the carrier substance comprises alginate or a derivative thereof, and wherein the at least one member of the transforming growth factor beta superfamily comprises a bone morphogenetic protein.
8. The system for affecting an anatomical structure of claim 7 , wherein the active agent further comprises a plurality of mesenchymal progenitor cells.
9. A kit for affecting an anatomical structure having a fillable space, the kit comprising:
a nanofiber mesh configured to substantially conform to an external surface of the anatomical structure, wherein at least a portion of the nanofiber mesh delineates a boundary between a milieu surrounding the anatomical structure and the fillable space of the anatomical structure; and
a flowable hydrogel system comprising at least one active agent, wherein the flowable hydrogel system is injected into and substantially fills the fillable space of the anatomical structure.
10. The kit for affecting an anatomical structure of claim 9 , wherein the nanofiber mesh has an average pore size of less than about 100 micrometers.
11. The kit for affecting an anatomical structure of claim 10 , wherein the nanofiber mesh further comprises a plurality of macropores.
12. The kit for affecting an anatomical structure of claim 10 , wherein the anatomical structure is bone, and wherein the flowable hydrogel comprises alginate or a derivative thereof, and wherein the active agent comprises a bone morphogenetic protein.
