Abstract

Devices, systems, and methods for delivery of an active agent into the eye of a subject can include an ocular active agent delivery device (40) having an active agent reservoir (44) disposed in an annular body (42), the annular body (42) being configured to fit inside of a lens capsule and at least partially encircling a line of sight of an intraocular lens within the lens capsule.

Claims

1. A homogeneous ocular active agent delivery device, comprising:

an annular body shaped to at least partially encircle a line of sight of an intraocular lens within a lens capsule, and the annular body includes at least two bulbous portions which are distributed and spaced from one another by narrower portions along an arc of the annular body, wherein the annular body is formed of an active agent matrix having the active agent dispersed therein such that the entire device throughout is formed of the active agent matrix having the active agent dispersed therein, such that the active agent matrix extends from external surfaces of the annular body throughout an interior of the annular body.

2. The device of claim 1, wherein the active agent includes at least one of bevacizumab, timolol, latanoprost, brimonidine, nepafenac, ranibizumab, antibiotic, prednisolone, fluocinolide, anti-VEGF aptamers, anti-VEGF Fab fragments, and integrin antagonists.

3. The device of claim 1, wherein the active agent matrix is capable of functioning as a valve to allow filling of the active agent matrix with the active agent and as a semipermeable membrane to allow diffusion of the active agent from the active agent matrix.

4. The device of claim 3, wherein the valve is a resealable elastomeric material.

5. The device of claim 1, wherein the active agent matrix is a biodegradable material.

6. The device of claim 1, wherein the annular body forms an incomplete circle.

7. The device of claim 1, wherein the annular body further includes at least one manipulation handle including eyelets to allow secure handling of the device during implantation or subsequent removal of the device from an eye.

8. The device of claim 1, further comprising at least one secondary active agent reservoir disposed within the annular body.

9. The device of claim 1, further comprising an osmotic pump operatively coupled to the active agent matrix, said osmotic pump being configured to facilitate delivery of the active agent from the active agent matrix.

10. The device of claim 1, further comprising a biosensor configured to detect at least one of levels of drug within the device to indicate need for refill, intraocular pressure, and intraocular markers of disease.

11. The device of claim 1, wherein the annular body is configured to fit inside a lens capsule.

12. The device of claim 1, wherein the active agent matrix contains at least one of ranibizumab, anti-VEGF aptamers, anti-VEGF Fab fragments, and integrin antagonists.

13. A method of treating an eye condition, comprising administering an active agent to the eye using the device of claim 1 by associating the device with an intraocular lens of the eye by inserting the device into a lens capsule such that the annular body at least partially encircles a line of sight of the intraocular lens.

14. The method of claim 13, wherein the eye condition is at least one of AMD, glaucoma, diabetic retinopathy, Retinopathy of Prematurity, uveitis, corneal transplant rejection, capsular fibrosis, posterior capsule opacification, retinal vein occlusions, cataracts, and infection.

15. The method of claim 13, wherein the active agent includes at least one of bevacizumab, timolol, latanoprost, brimonidine, nepafenac, ranibizumab, antibiotic, prednisolone, fluocinolide, anti-VEGF aptamers, anti-VEGF Fab fragments, and integrin antagonists.

16. The method of claim 13, wherein the device is inserted into the lens capsule so that the device is located in an anterior portion of the lens capsule.

17. A homogeneous ocular active agent delivery device, comprising:

an annular body shaped to at least partially encircle a line of sight of an intraocular lens within the lens capsule, wherein the annular body is formed of an active agent matrix having the active agent dispersed therein such that the entire device throughout is formed of the active agent matrix having the active agent dispersed therein, such that the active agent matrix extends from external surfaces of the annular body throughout an interior of the annular body, and wherein the annular body further includes at least one manipulation handle including eyelets to allow secure handling of the device during implantation or subsequent removal of the device from an eye, and wherein the annular body further includes at least two bulbous portions which are distributed and spaced from one another by narrower portions along an arc of the annular body.

18. The device of claim 17, wherein the active agent includes at least one of ranibizumab, anti-VEGF aptamers, anti-VEGF Fab fragments, and integrin antagonists.

19. The device of claim 17, wherein the active agent matrix is a biodegradable material.

20. The device of claim 19, wherein the biodegradable material includes at least one of PLGA, PVA, PEG, PLA, PGA, HPMC, polycaprolactone, hyaluronic acid, albumin, and block copolymers thereof.

21. The device of claim 17, wherein the annular body forms an incomplete circle.

22. The device of claim 21, wherein the at least one manipulation handle including eyelets is positioned at a terminus of the annular body.
