Title:
IMPLANT TO TREAT RETINAL VEIN OCCLUSION
Document Type and Number:
WIPO Patent Application WO/2022/093832
Kind Code:
A4
Abstract:
Intraocular implants include a proximal end, a distal end, and a lumen, disposed between the proximal end and the distal end. When implanted into an eye, the proximal end is in fluid communication with a retinal vein of the eye and the distal end is in fluid communication with a choroid of the eye. Via this fluid communication, the intraocular implants treat retinal vein occlusion.

Claims:
AMENDED CLAIMS received by the International Bureau on 28 April 2022 (28.04.2022)

1. An intraocular implant comprising: a proximal end; a distal end; and a lumen, disposed between the proximal end and the distal end, wherein, when implanted into an eye, the intraocular implant is configured to pierce a retinal vein of the eye, such that the proximal end is in direct fluid communication with the retinal vein of the eye and the distal end is in direct fluid communication with a choroid of the eye.

2. The intraocular implant of Claim 1, wherein the distal end of the implant includes a plurality of retention features configured for retention in the choroid of the eye or in a sclera of the eye.

3. The intraocular implant of Claim 2, wherein the plurality of retention features includes a beveled end with a flange.

4. The intraocular implant of Claim 1, wherein the distal end includes a plurality of prongs, configured to capture the retinal vein of the eye prior to implantation and piercing.

5. The intraocular implant of Claim 1 , wherein the distal end includes a blade, configured to transect the retinal vein of the eye.

6. The intraocular implant of Claim 1, wherein the distal end is configured to receive a trocar blade, the trocar blade configured to transect the retinal vein of the eye.

7. The intraocular implant of Claim 1, wherein the proximal end is configured for manipulation by a surgeon.

8. The intraocular implant of Claim 1, wherein the proximal end includes a rectangular protrusion.

9. The intraocular implant of Claim 1 , wherein the lumen includes a fluid pathway, and wherein the implant includes a fluid inlet at the proximal end and a fluid outlet at the distal end, such that the fluid pathway is disposed between the fluid inlet and the fluid outlet and the fluid pathway is in fluid communication with each of the fluid inlet and the fluid outlet.

10. An intraocular implant system comprising: an intraocular implant, including a proximal end, a distal end, and a lumen, disposed between the proximal end and the distal end; and a trocar, wherein a distal end of the trocar is configured to extend through the intraocular implant via the lumen, wherein, when implanted into an eye, the intraocular implant system is configured to transect or puncture a retinal vein of an eye and create a wound channel in the eye.

11. The intraocular implant system of Claim 10, wherein the distal end of the intraocular implant is configured to reside within a choroid of the eye or a sclera of the eye.

12. The intraocular implant system of Claim 10, wherein the distal end of the intraocular implant includes a plurality of retention features configured for retention in a choroid of the eye or a sclera of the eye.

13. The intraocular implant system of Claim 12, wherein the plurality of retention features of the intraocular implant includes a beveled end with a flange.

14. The intraocular implant system of Claim 10, wherein the distal end of the intraocular implant includes a plurality of prongs, configured to capture the retinal vein of the eye prior to implantation.

15. The intraocular implant system of Claim 10, wherein the distal end of the trocar includes a blade, configured to transect or puncture the retinal vein of the eye.

AMENDED SHEET (ARTICLE 19)

16. The intraocular implant system of Claim 10, wherein the proximal end of the intraocular implant is configured for manipulation by a surgeon.

17. The intraocular implant system of Claim 10, wherein the proximal end of the intraocular implant includes a rectangular protrusion.

18. The intraocular implant system of Claim 10, wherein the lumen includes a fluid pathway, and wherein the intraocular implant includes a fluid inlet at the proximal end and a fluid outlet at the distal end, such that the fluid pathway is disposed between the fluid inlet and the fluid outlet and the fluid pathway is in fluid communication with each of the fluid inlet and the fluid outlet.

19. The intraocular implant system of Claim 10, further comprising a cannula, such that the trocar and the intraocular implant are configured to reside within the cannula prior to implantation.

20. The intraocular implant system of Claim 19, wherein the cannula includes a plurality of notches at a distal end, the plurality of notches configured to capture the retinal vein for alignment with the intraocular implant.
