Adjustable flow rate glaucoma shunt and method of using same
First Claim
1. An adjustable flow rate implant shunt device for draining aqueous humor from an eye, comprising:
- a hollow tubular member having a first end and a second end, the first end being sealed and the second end being open, the tubular member having a size and shape to allow one of the ends to be inserted into an anterior portion of an eye and wherein the shunt device is sealed, allowing no aqueous-humor to flow from the device after insertion into the eye, and an episcleral plate, the plate being mounted adjacent to one of the ends.

Abstract
An adjustable flow rate implantable shunt device for use in treating glaucoma is provided. The device comprises a tubular member having a first sealed end and an open second end which are joined by a wall. The first end is inserted into the anterior portion of the eye for receipt of aqueous humor, and the second end is fastened to the sclera of the eye. The first end of the shunt device is sealed when implanted, so that flow of aqueous humor through the device immediately after implantation is prevented. After a sufficient post-implantation period such that a fibrous capsule has formed around the shunt device, at least one perforation is made along the segment of the wall of the tubular member which is located within the anterior portion of the eye to allow aqueous humor to flow through and out of the device.
