Abstract

The present disclosure provides an ophthalmology implant and methods for treating glaucoma or optic neural transmission deficiency, wherein at least a portion of the implant is made of or includes a nanometer-sized substance, such as nanotubes, nanofibers, sheets from nanotubes, nanowires, nanofibrous mesh and the like.

Claims

1. An implant for treating glaucoma comprising:

an inlet portion having an inlet lumen extending therethrough, the inlet lumen being in fluid communication with the anterior chamber of an eye when the implant is positioned within the trabecular meshwork of the eye; and

an outlet portion having an outlet lumen extending therethrough, the outlet lumen being in fluid communication with the inlet lumen and with an aqueous outflow channel of the eye when the outlet portion is disposed within the aqueous outflow channel of the eye and thereby permitting the transfer of fluid from the anterior chamber into the aqueous outflow channel;

wherein at least a portion of the implant comprises a nanostructure; and

wherein the aqueous outflow channel comprises at least one of Schlemm'"'"'s canal, a collector channel, and an episcleral vein.

2. The implant of claim 1, wherein the nanostructure comprises at least one of a nanotube, a nanofiber, a sheet of nanotubes, a nanowire, and a nanomesh.

3. The implant of claim 1, wherein the nanostructure comprises a nanotube.

4. The implant of claim 1, wherein the nanostructure comprises a nanofiber.

5. The implant of claim 1, wherein the nanostructure comprises a sheet of nanotubes.

6. The implant of claim 1, wherein the nanostructure comprises a nanomesh.

7. The implant of claim 1, wherein the nanostructure comprises a carbon nanotube.

8. The implant of claim 1, wherein the nanostructure comprises a carbon nanofiber.

9. The implant of claim 1, wherein the nanostructure comprises a single-wall carbon nanostructure.

10. The implant of claim 1, wherein the nanostructure comprises a multi-wall carbon nanostructure.

11. The implant of claim 1, wherein a long axis of the nanostructure is aligned substantially parallel to the flow of fluid through one of the lumens of the stent.

12. The implant of claim 1, wherein the nanostructure is electrically conductive.

13. The implant of claim 1, wherein the inlet lumen and the outlet lumen are substantially parallel.

14. The implant of claim 1, wherein at least one of the inlet portion and the outlet portion comprises a wall having at least a portion thereof comprising a nanostructure.

15. The implant of claim 14, wherein the wall has a wall thickness less than about 100 nanometers.

16. The implant of claim 1, wherein the implant further comprises means for detecting intraocular pressure.

17. The implant of claim 1, wherein the implant further comprises an intraocular pressure sensor.

18. The implant of claim 1, wherein the implant further comprises a therapeutic agent.

19. The implant of claim 1, wherein the implant further comprises means for anchoring the implant in the eye.

20. The implant of claim 1, wherein the implant further comprises an anchor that substantially prevents expulsion of the implant from the eye.

21. The implant of claim 1, wherein the implant is substantially linear prior to insertion in the eye.

22. An implant for treating glaucoma comprising:

an inlet portion having an inlet that is configured to receive fluid from the anterior chamber of an eye when the implant is positioned within the trabecular meshwork of the eye;

an outlet portion having an outlet that is configured to conduct fluid from the anterior chamber into at least one of Schlemm'"'"'s canal, a collector channel, and an episcleral vein of the eye when the outlet portion is positioned within the eye, thereby permitting the transfer of fluid from the anterior chamber into that at least one of Schlemm'"'"'s canal, a collector channel, and an episcleral veins; and

a layer of nanotubes disposed in or on the implant.

23. The implant of claim 22, wherein the layer of nanotubes is disposed in or on an interior portion of the implant.

24. The implant of claim 22, wherein the layer of nanotubes is disposed in or on the implant by spraying a matrix comprising the nanotubes on the implant.

25. The implant of claim 22, wherein the layer of nanotubes is disposed in or on the implant by dipping the implant into a matrix comprising the nanotubes.

26. The implant of claim 22, wherein the implant further comprises a therapeutic agent.

27. The implant of claim 22, wherein the implant is substantially I-shaped.

28. The implant of claim 22, wherein the implant is substantially linear prior to insertion in the eye.

29. The implant of 22, wherein the implant further comprises an anchor that substantially prevents expulsion of the implant from the eye.
