1. An ocular implant configured to maintain patency of Schlemm'"'"'s canal of an eye in a stenting fashion, the ocular implant comprising:
- a body of biocompatible material of a size and shape adapted to facilitate the passage of aqueous humor into and across a trabecular meshwork of the eye;
the body having a length and shape adapted to be circumferentially retained within a portion of Schlemm'"'"'s canal,wherein the body is curved,wherein the body is non-tubular, andwherein the body comprises at least one opening configured to facilitate passage of aqueous humor.

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.

20. A shunt for implantation within an eye, the shunt comprising:
-
a proximal end; a distal end; and a non-tubular curved body disposed between the proximal end and the distal end, the curved body comprising a first edge disposed on a first side of a longitudinal axis of the curved body and a second edge disposed on a second side of a longitudinal axis of the curved body; and a portal positioned at a location between the proximal end and the distal end along the curved body, wherein at least the curved body is configured to be received circumferentially within a portion of Schlemm'"'"'s canal of the eye. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
