Abstract

An implant for treating an ocular disorder has a longitudinal implant axis, an outflow portion passing therethrough, a plurality of longitudinally spaced openings therein, an inflow portion, and an anchoring member that extends from the implant and is disposed distally of the openings. The outflow portion is shaped and sized to be introduced into Schlemm's canal of an eye at an angle, and received at least partially within Schlemm's canal regardless of its rotational orientation about the axis during introduction. The openings allow fluid communication from a lumen within the outflow portion to a location outside the outflow portion. The inflow portion is configured to be positioned within an anterior chamber of the eye to permit fluid communication from the anterior chamber to the outflow portion. The axis extends through a trabecular meshwork of the eye and is generally orthogonal to Schlemm's canal during the fluid communication.
