Ocular implants with anchors and methods thereof
First Claim
1. An implant for treating an ocular disorder, the implant comprising:
- an inlet portion configured to be positioned in the anterior chamber of an eye;
an outlet portion in fluid communication with the inlet portion, the outlet portion configured to be positioned at least partially in a physiological outflow pathway of the eye; and
a scleral anchor comprising a sharp end extending from the outlet portion such that the outlet portion is located intermediate the inlet portion and the scleral anchor, said scleral anchor configured to penetrate partially the sclera of the eye when the implant is positioned in the eye such that aqueous humor flows from the anterior chamber into the inlet portion, then into the outlet portion, and then into the physiological outflow pathway.

Abstract
Intraocular stents and applicators are disclosed for treating glaucoma. The stents are configured to extend between the anterior chamber of the eye and Schlemm'"'"'s canal for enhancing outflow of aqueous from the anterior chamber so as to reduce intraocular pressure. The stents can have features for anchoring the stent into Schlemm'"'"'s canal as well as preventing the walls of Schlemm'"'"'s canal from closing the outlet of the stents. The applicators can be steerable so as to make implantation easier. Additionally, the applicators can be configured to hold a plurality of stents so that multiple stents can be implanted through one incision without removing the applicator from the incision between serial implantations.

15. A method of treating glaucoma, comprising:
-
inserting an implant through an incision in the eye, the implant having an inlet portion and an outlet portion; positioning the implant in the eye by piercing through a first wall of Schlemm'"'"'s canal, such that fluid flows from the anterior chamber through the inlet portion and then through the outlet portion of the implant and into Schlemm'"'"'s canal of the eye; and
piercing through a second, substantially opposite wall of Schlemm'"'"'s canal. - View Dependent Claims (16, 17, 18, 19, 20)

21. An ocular shunt comprising:
-
an inlet portion configured to be positioned in a first space within an eye; an outlet portion in fluid communication with the inlet portion, the outlet portion configured to be positioned at least partially in a second space within the eye; and an anchor comprising a sharp end extending from the outlet portion such that the outlet portion is located intermediate the inlet portion and the anchor, said anchor configured to anchor the shunt in eye tissue when the shunt is positioned in the eye such that fluid flows from the first space into the inlet portion, then into the outlet portion, and then into the second space. - View Dependent Claims (22, 23, 24, 25, 26)
