Glaucoma stent for treating glaucoma and methods of use
First Claim
1. A method for inserting a trabecular stent through a trabecular meshwork of an eye, the method comprising:
- retaining the trabecular stent within a lumen of an applicator, wherein the applicator comprises a slidably movable piercing member located within the lumen of the applicator;
delivering the applicator to about a surface of the trabecular meshwork;
advancing the piercing member through a lumen of the trabecular stent for creating an opening at the trabecular meshwork; and
inserting said trabecular stent into said opening.

Abstract
Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
