Ocular implants and methods for delivering ocular implants into the eye
First Claim
1. An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye, the eye having an iris defining a pupil, the implant comprising:
- a longitudinally extending curved body including a proximal portion and a distal portion, the distal portion of the curved body having a central longitudinal axis defined by a radius of curvature and a lateral cross section having a first lateral extent and a second lateral extent, an aspect ratio of the first lateral extent to the second lateral extent being greater than or equal to about two;
the distal portion of the curved body defining a longitudinal channel including a channel opening, the channel opening included in defining the first lateral extent; and
the curved body being adapted and configured such that the distal portion of the curved body resides in Schlemm'"'"'s canal and the proximal portion extends into the anterior space of the eye while the ocular implant assumes an orientation in which the channel opening is adjacent a major side of Schlemm'"'"'s canal when the ocular implant is implanted.

Abstract
An ocular implant is provided. In some embodiments, the ocular implant includes a body that is curved about a longitudinal central axis and a distal body portion that defines a longitudinal channel including a channel opening. The implant is sized and configured such that the ocular implant assumes an orientation in which the channel opening is adjacent a major side of Schlemm'"'"'s canal when the ocular implant is disposed in Schlemm'"'"'s canal. Methods for delivering ocular implants into Schlemm'"'"'s canal are also provided. Some methods include covering openings in the ocular implant, advancing the implant into Schlemm'"'"'s canal while at least some of the openings are covered, and uncovering the openings while the distal portion of the implant is disposed in Schlemm'"'"'s canal.

10. An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye, the eye having an iris defining a pupil, the implant comprising:
-
a longitudinally extending curved body including a proximal portion and a distal portion, the distal portion of the curved body having a central longitudinal axis defined by a radius of curvature and a lateral cross section having a first lateral extent and a second lateral extent, an aspect ratio of the first lateral extent to the second lateral extent being greater than or equal to about two, the lateral cross section further having a shape defining an inner concave surface and an outer convex surface, each extending over a substantial portion of the length of the distal section; the inner concave surface defining a longitudinal channel extending over a substantial portion of the length of the distal portion and including a channel opening, the channel opening being across from the inner concave surface; and the body being adapted and configured such that the ocular implant assumes an orientation in which the channel opening is adjacent a major side of Schlemm'"'"'s canal when the ocular implant is disposed in the eye. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye, the eye having an iris defining a pupil, the implant comprising:
-
a longitudinally extending body having a lateral cross section defining a first lateral extent and a second lateral extent, an aspect ratio of the first lateral extent to the second lateral extent being greater than or equal to two; the body being curved about a longitudinal central axis so that the lateral cross section further defines an inner concave surface and an outer convex surface; a distal portion of the body defining a longitudinal channel including a channel opening, the channel opening being across from the inner concave surface; and the body being adapted and configured such that the ocular implant assumes an orientation in which the channel opening is adjacent a major side of Schlemm'"'"'s canal when the ocular implant is disposed in Schlemm'"'"'s canal. - View Dependent Claims (20, 21)
