Shunt device and method for treating glaucoma
First Claim
1. An ocular device comprising:
- a body for implantation into Schlemm'"'"'s canal of an eye comprising a portion for insertion into the canal, and a portion sized to extend from a position within the canal to a position within an anterior chamber of the eye; and
wherein the body is configured and dimensioned such that implantation of the body in living tissue of the canal permits dynamic flow of aqueous humor toward a venous system of the eye; and
wherein the device is coated with a therapeutic agent.

Abstract
Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involve bypassing diseased trabecular meshwork with the use of a seton implant. The seton implant is used to prevent a healing process known as filling in, which has a tendency to close surgically created openings in the trabecular meshwork. The surgical method and novel implant are addressed to the trabecular meshwork, which is a major site of resistance to outflow in glaucoma. In addition to bypassing the diseased trabecular meshwork at the level of the trabecular meshwork, existing outflow pathways are also used or restored. The seton implant is positioned through the trabecular meshwork so that an inlet end of the seton 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.

28. An ocular device for use in an eye having an anterior chamber and a Schlemm'"'"'s canal for relieving intraocular pressure by facilitating flow from the anterior chamber of the eye into Schlemm'"'"'s canal, the implant comprising:
-
a proximal portion in fluid communication with a distal portion, the proximal portion being sized and shaped to fit at least partially in the anterior chamber of the eye, and the distal portion being sized and shaped to fit at least partially in Schlemm'"'"'s canal of the eye;
wherein the device is coated with a therapeutic agent.

29. An ocular device for use in a living eye having an anterior chamber and a Schlemm'"'"'s canal for relieving intraocular pressure by facilitating drainage from the anterior chamber of the living eye into Schlemm'"'"'s canal, the implant comprising:
-
a proximal portion in fluid communication with a distal portion, the proximal portion being sized and shaped to fit at least partially in the anterior chamber of the eye, and the distal portion being sized and shaped to fit at least partially in Schlemm'"'"'s canal of the eye;
wherein the device comprises a therapeutic agent. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
