Ocular implants and methods for delivering ocular implants into the eye
First Claim
1. A method of placing an ocular implant into Schlemm'"'"'s canal of a patient'"'"'s eye, the ocular implant having a lateral cross section with 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 method comprising:
- placing the ocular implant within Schlemm'"'"'s canal with the first lateral extent oriented with a first side of Schlemm'"'"'s canal and the second lateral extent oriented with a second side of Schlemm'"'"'s canal, the first side of Schlemm'"'"'s canal being longer than the second side;
wherein the placing step comprises advancing the ocular implant out of a cannula into Schlemm'"'"'s canal; and
further comprising placing a distal opening of the cannula in fluid communication with Schlemm'"'"'s canal.

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.

9. A method of placing an ocular implant into Schlemm'"'"'s canal of a patient'"'"'s eye, the method comprising:
-
advancing a distal end of a cannula through trabecular meshwork into Schlemm'"'"'s canal; placing a distal opening of the cannula in fluid communication with Schlemm'"'"'s canal; advancing the ocular implant through the distal opening of the cannula into Schlemm'"'"'s canal, the ocular implant having a lateral cross section with 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; and placing the ocular implant within Schlemm'"'"'s canal with the first lateral extent oriented with a first side of Schlemm'"'"'s canal and the second lateral extent oriented with a second side of Schlemm'"'"'s canal, the first side of Schlemm'"'"'s canal being longer than the second side. - View Dependent Claims (10, 11, 12, 13, 14)
