Glaucoma implant
First Claim
1. A device for draining fluid from a first region of an eye to a second region of an eye, said device comprising:
- a single thin elastomeric plate having oppositely-disposed first and second primary surfaces, each of said surfaces being disposed to provide contact between said first region of said eye and substantially all of said first and second surfaces of said plate to form a bleb in said first region of said eye around said plate when said device is implanted within said eye, said plate sufficiently flexible to conform to the patient'"'"'s eye when the device is implanted in said eye; and
a tube having a first end adjacent said first surface of said plate and a second end extendable into said second region of said eye to provide fluid communication between said first region of said eye and said second region of said eye.

Abstract
An implant for use in the treatment of glaucoma is disclosed wherein the implant comprises an elastomeric plate having a non-valved elastomeric drainage tube attached thereto. The plate is elliptical in-shape and curved so as to conform to the curvature of the eye. The plate is inserted into the eye in an incision made in the Tenon'"'"'s capsule and sutured to the sclera. The drainage tube is tunnelled through the Tenon'"'"'s capsule and cornea and inserted into the anterior chamber, thus providing patent fluid communication between the anterior chamber and the elastomeric plate. The flexible structure of the plate allows the plate to be easily inserted, thus reducing the surgical procedure length. In addition, the pliable material minimizes the risk of damage and trauma to surrounding tissues in the insertion process.

8. An implant for draining fluid an eye comprising:
-
a single thin carrier plate sufficiently flexible to conform with the outer surface of said eye such that substantially all of its surfaces are engageable with the surface of a first region of said eye; and a tube having a first end attached to a surface of said plate and extendable into a second region of said eye.

9. An implant for draining fluid from an eye, comprising:
-
a single thin elastomeric plate having first and second primary surfaces, configured such that substantially all of said first and second surfaces are engageable with a first region of said eye, said plate having sufficient resilience so that if said plate is folded flat against itself and released, said plate will return to its original, as-molded condition; and a tube having a first end attached to one of said first and second surfaces of said plate and a second end extendable into a second region of said eye to provide a fluid passage between said first and second regions of said eye.
