Ocular delivery systems and methods
First Claim
1. A single-handed, single-operator, ab-interno method for introducing viscoelastic fluid into Schlemm'"'"'s canal comprising:
- advancing a cannula at least partially through the anterior chamber of the eye and into Schlemm'"'"'s canal, wherein the cannula is coupled to a handle of a single-handed, single-operator controlled device, a portion of the handle defining a fluid reservoir and comprising a drive assembly configured to advance a flexible slidable conduit from the cannula and to deliver a volume of viscoelastic fluid;
advancing the flexible slidable conduit from the cannula into Schlemm'"'"'s canal along an arc of the canal; and
delivering the volume of viscoelastic fluid from the reservoir into Schlemm'"'"'s canal through the flexible slidable conduit, wherein the volume of viscoelastic fluid delivered corresponds to the length the flexible conduit has been advanced along the arc.

Abstract
Described here are systems and methods for accessing Schlemm'"'"'s canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm'"'"'s canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.
