OCULAR IMPLANT
First Claim
1. An ocular implant, comprising:
- a small tube, the wall surface of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct wherein a first opening allowing ocular humor to flow in and a second opening allowing the ocular humor to be discharged is provided, and wherein the wall surface is formed by a liquid-tight material,wherein 35% of the longitudinal extent of the small tube from the first opening is positioned in the anterior eye chamber andwherein at least one pressure-controlled valve is disposed in the area of the wall surface, which is disposed at distance from the first opening equal to between 0% and 35% of the longitudinal extent of the small tube.

Abstract
The present invention relates to an ocular implant, particularly a glaucoma stent.
It is the object of the present invention to devise an ocular implant which allows the ocular eye pressure to be regulated, i.e., to be maintained at a desired level, while preventing the flow resistance from increasing over time, for example due to fibrosis.
In order to achieve this object, the ocular implant according to the invention comprises a small tube (5), the wall surface (3) of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct, wherein a first opening (1) allowing ocular humor to flow in and a second opening (2) allowing the ocular humor to be discharged is provided, and wherein the wall surface (3) is formed by a liquid-tight material, and wherein at least one pressure-controlled valve (4) is disposed in the area of the wall surface (3).
