Publication number: 20130231603Abstract: 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.Type: ApplicationFiled: April 18, 2013Publication date: September 5, 2013Inventors: John Wardle, Andrew T.

Publication number: 20110098809Abstract: An ocular implant and delivery system having a channel tool adapted to extend through at least a portion of Schlemm's canal of a human eye and to determine whether the Schlemm's canal portion provides a suitable location for the delivery of an ocular implant; an ocular implant adapted to be disposed within Schlemm's canal of a human eye; and a cannula comprising a distal opening adapted to deliver the channel tool and the ocular implant into Schlemm's canal of the eye. The invention also provides a method of treating glaucoma in a human eye including the steps of inserting a distal exit port of a cannula at least partially into Schlemm's canal of the eye; delivering a channel tool through the cannula into Schlemm's canal; delivering an ocular implant through the cannula into Schlemm's canal; and removing the channel tool and the cannula from the eye while leaving the ocular implant in place within Schlemm's canal.Type: ApplicationFiled: October 25, 2010Publication date: April 28, 2011Inventors: John Wardle, Andrew T. Schieber, Kenneth M. Galt
