Abstract
The present invention provides a shunt for the flow of aqueous humor from the anterior chamber of the eye to Schlemm'"'"'s canal. The device comprises at least one lumen and optionally has at least one anchor extending from the proximal portion within the anterior chamber to assist in placement and anchoring of the device in the correct anatomic position.

33. A method of controlling the flow of aqueous humor in a living eye having an anterior chamber, a Schlemm'"'"'s canal, and an episcleral venous system, the method comprising:
-
introducing into the living eye an indwelling tubular body which leads from the anterior chamber into Schlemm'"'"'s canal to provide an aqueous humor directing channel out of the anterior chamber; and
draining aqueous humor through the tubular body to reduce intraocular pressure in the living eye. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A method of controlling the flow of aqueous humor in a living eye having an anterior chamber, a Schlemm'"'"'s canal, and an episcleral venous system, the method comprising:
-
introducing a tubular body between Schlemm'"'"'s canal and the anterior chamber, wherein the tubular body provides a first aqueous humor directing channel from the anterior chamber toward Schlemm'"'"'s canal; and
draining aqueous humor through the tubular body to reduce build-up of aqueous humor in the living eye. - View Dependent Claims (45)

46. A method of controlling the flow of aqueous humor in a living eye having an anterior chamber, a Schlemm'"'"'s canal, and an episcleral venous system, the method comprising:
-
placing a substantially hollow device in the living eye leading from Schlemm'"'"'s canal to the anterior chamber of the eye, wherein device provides an elongated aqueous humor directing channel within Schlemm'"'"'s canal to guide the flow of aqueous humor from the anterior chamber toward the episcleral venous system, wherein the outer diameter of the portion of the device placed within Schlemm'"'"'s canal is between about 0.1 mm and 0.5 mm; and
draining aqueous humor along the elongated aqueous humor directing channel to maintain pressure above approximately 6.0 mmHg in the living eye. - View Dependent Claims (47)

48. A method of controlling the flow of aqueous humor in a living eye having an anterior chamber, a Schlemm'"'"'s canal, and an episcleral venous system, the method comprising:
-
introducing a tubular body into Schlemm'"'"'s canal and the anterior chamber to provide a non-linear aqueous humor directing channel from the anterior chamber toward the episcleral venous system; and
draining aqueous humor through the tubular body at a sufficient flow rate to permit intraocular pressure to be reduced in the living eye. - View Dependent Claims (49, 50, 51, 52)

53. A method of controlling the flow of aqueous humor in a living eye having an anterior chamber, a Schlemm'"'"'s canal, and an episcleral venous system, the method comprising:
-
providing a tubular body in Schlemm'"'"'s canal comprising an elongated aqueous humor directing channel, wherein the outer diameter of the tubular body in Schlemm'"'"'s canal is between about 0.1 mm and 0.5 mm, and the aqueous humor directing channel guides the flow of aqueous humor from the anterior chamber toward the episcleral venous system; and
draining aqueous humor along the elongated aqueous humor directing channel at a sufficient flow rate to maintain pressure above approximately 6.0 mmHg in the living eye. - View Dependent Claims (54, 55)
