Abstract

A glaucoma treatment device for directing the flow of aqueous humor and reducing intraocular pressure for angle closure glaucoma is disclosed. The glaucoma device comprises an aqueous transporting element for transporting aqueous humor to bypass dysfunctional anatomical iris closure and restoring existing outflow pathways of the anatomical iris closure. The aqueous transporting element has an inlet end and an outlet end, wherein the inlet end is positioned inside an anterior chamber of an eye beyond an edge of the dysfunctional anatomic iris closure and the outlet end is positioned in proximity of trabecular meshwork of the eye. The device also serves to stent the space between the iris and an inner surface of a cornea of the eye.

Claims

A glaucoma device for reducing intraocular pressure in a patient having angle closure glaucoma, the glaucoma device comprising an aqueous transporting element for transporting aqueous humor to bypass dysfunctional anatomical iris closure and restoring existing outflow pathways of said anatomical iris closure, the aqueous transporting element having an inlet end and an outlet end, wherein the inlet end is positioned inside an anterior chamber of an eye beyond an edge of said dysfunctional anatomic iris closure and the outlet end is positioned at proximity of trabecular meshwork of the eye.

2. The glaucoma device according to claim 1, wherein said aqueous transporting element is an elongate tubular member.

3. The glaucoma device according to claim 2, wherein the elongate tubular member further comprises an inlet section having said inlet end and an outlet section having said outlet end, the inlet section being at an angle in relation to the outlet section.

4. The glaucoma device according to claim 3, wherein the outlet section is positioned at an opening of trabecular meshwork, the opening being created by incision or perforation.

5. The glaucoma device according to claim 1, wherein the device is made of a biocompatible material selected from a group consisting of polyvinyl alcohol, polyvinyl pyrolidone, collagen, heparinized collagen, chemically treated collagen, polytetrafluoroethylene, expanded polytetrafluoroethylene, fluorinated polymer, fluorinated elastomer, flexible fused silica, silicone, polyurethane, poly(methyl methacrylate), acrylic, polyolefin, polyester, polysilicon, polypropylene, hydroxyapetite, titanium, gold, silver, platinum, biodegradable material, bioresorable material, and a mixture thereof.

6. The glaucoma device according to claim 5, wherein the biocompatible material comprises surface coating with a coating material selected from the group consisting of Teflon, polyimide, hydrogel, heparin, hydrophilic coating substrate, therapeutic drug, and a combination thereof.

7. The glaucoma device according to claim 2, wherein the device is made of a porous material.

8. The glaucoma device according to claim 2, wherein the device is made of a solid material with many interconnected tiny holes for communicating aqueous humor throughout said interconnected holes.

9. The glaucoma device according to claim 4, wherein the outlet end further comprises a trumpet flange adapted for stabilizing the outlet end inside Schlemm'"'"'s canal of the eye.

10. The glaucoma device according to claim 7 or claim 8, the device further comprising at least an elongate trough for transmitting aqueous humor between the inlet end and the outlet end of the glaucoma device.

11. The glaucoma device according to claim 10, wherein said at least one elongate trough is in communication with a lumen of the glaucoma device between the inlet end and the outlet end.

12. The glaucoma device according to claim 3, wherein the angle is between about 120 degrees to about 185 degrees.

13. The glaucoma device according to claim 1, wherein said aqueous transporting element is an annular member, the annular member being placed inside the anterior chamber, wherein the inlet end is positioned beyond an edge of said dysfunctional anatomic iris closure and the outlet end is positioned at proximity of trabecular meshwork of the eye.

14. The glaucoma device according to claim 13, wherein the annular member is selected from the group consisting of a ring, an oval ring, and a semi-open ring configured to fit inside the anterior chamber of the eye.

15. The glaucoma device according to claim 14, wherein the outlet end of said annular member further comprises at least one protruded construct adapted to be positioned inside an opening of trabecular meshwork, the opening being created by incision or perforation.

16. The glaucoma device according to claim 13 or claim 15, wherein the device is made of a biocompatible material selected from a group consisting of polyvinyl alcohol, polyvinyl pyrolidone, collagen, heparinized collagen, chemically treated collagen, polytetrafluoroethylene, expanded polytetrafluoroethylene, fluorinated polymer, fluorinated elastomer, flexible fused silica, silicone, polyurethane, poly(methyl methacrylate), acrylic, polyolefin, polyester, polysilicon, biodegradable material, bioresorable material, and a mixture thereof.
