1. A stent for use in an eye to enhance drainage of aqueous fluid from an anterior chamber of an eye into one or more collecting channels on an outer wall of Schlemm'"'"'s canal of the eye, wherein the stent comprises:
- a biocompatible metal body shaped to reside partially within Schlemm'"'"'s canal, the body having a trough-like aspect that is oriented to open toward the outer wall of Schlemm'"'"'s canal when positioned in the eye,wherein the trough-like aspect extends to a distal end of the body,wherein the body further comprises an inlet at a proximal end shaped to reside at least partially within the anterior chamber,wherein the body further comprises a fenestration located between the proximal end and the distal end of the body.

Abstract
Shunt devices and a method for continuously decompressing elevated intraocular pressure in eyes affected by glaucoma by diverting excess aqueous humor from the anterior chamber of the eye into Schlemm'"'"'s canal where post-operative patency can be maintained with an indwelling shunt device which surgically connects the canal with the anterior chamber. The shunt devices provide uni- or bi-directional flow of aqueous humor into Schlemm'"'"'s canal.

9. An implant designed to relieve elevated intraocular pressure, the implant comprising:
-
a biocompatible metal stent having approximately 6 mm of its length forming a curved length shaped to reside within Schlemm'"'"'s canal of an eye, wherein the curved length has a trough-like shape, the stent being configured such that the trough-like shape is oriented to open toward one or more collecting channels of Schlemm'"'"'s canal when positioned in the eye, wherein the curved length further includes a fenestration, and wherein the stent further includes an inlet at its proximal end shaped to reside at least partially within the anterior chamber. - View Dependent Claims (10, 11, 12, 13, 14, 15)
