Abstract

Glaucoma can be treated by implanting an intraocular shunt into an eye. The eye has an anterior chamber and sclera. A shunt can be placed into the eye to establish fluid communication between the anterior chamber of the eye and a space between layers of the sclera.

First claim

What is claimed is:

1. A method comprising inserting, through a cornea, an implant in an eye having (i) an anterior chamber and (ii) a sclera comprising layers, thereby establishing fluid communication between the anterior chamber and a space between the layers.

2. The method of claim 1 , wherein the implant comprises an intraocular shunt, and wherein the inserting comprises inserting the intraocular shunt through the cornea and into the anterior chamber.

3. The method of claim 1 , wherein the inserting comprises, from within the anterior chamber, forming a slit in sclera.

4. The method of claim 1 , wherein the inserting comprises inserting, through the cornea and into the anterior chamber, a hollow shaft carrying an intraocular shunt.

5. The method of claim 4 , further comprising, from within the anterior chamber, piercing the sclera with the shaft such that a distal tip of the shaft enters the sclera.

6. The method of claim 5 , wherein the inserting comprises, while maintaining the shaft distal tip positioned in the sclera, advancing the shunt from the hollow shaft to position a first end of the shunt in the anterior chamber and a second end of the shunt between layers of sclera such that the shunt forms a passage from the anterior chamber to the sclera.

7. The method of claim 1 , wherein the inserting comprises advancing a pusher component to distally advance the implant into the sclera.

8. The method of claim 7 , wherein the advancing the pusher component comprises rotating a portion of a deployment mechanism.

9. A method comprising inserting an intraocular shunt through a cornea of an eye, and positioning an outlet end of the shunt between layers of sclera and an inlet end of the shunt in an anterior chamber of the eye.

10. The method of claim 9 , further comprising, from within the anterior chamber, forming a slit in sclera.

11. The method of claim 10 , wherein the positioning comprises positioning the outlet end in the slit.

12. The method of claim 9 , wherein the positioning comprises positioning the shunt outlet end in the sclera between deep and superficial layers of sclera.

13. The method of claim 9 , wherein the positioning comprises advancing a pusher component to distally advance the shunt into the sclera.

14. The method of claim 13 , wherein the advancing the pusher component comprises rotating a portion of a deployment mechanism.

15. A method comprising inserting a shunt into an anterior chamber of the eye through a cornea, and positioning an outlet end of the shunt between layers of sclera for providing fluid communication to a space between the layers.

16. The method of claim 15 , further comprising actuating a portion of a deployment device to distally advance the shunt into the space.

17. The method of claim 16 , wherein the actuating comprises rotating the portion of the deployment device.

18. The method of claim 17 , wherein the rotating causes distal advancement of a pusher component to distally advance the shunt into the sclera.

19. The method of claim 15 , wherein the inserting comprises while maintaining a hollow shaft distal tip positioned in the sclera, advancing the shunt from the hollow shaft to position a first end of the shunt in the anterior chamber and a second end of the shunt between layers of sclera such that the shunt forms a passage from the anterior chamber to the sclera.

20. The method of claim 15 , further comprising, from within the anterior chamber, forming a slit in sclera.
