Shunt and method treatment of glaucoma
First Claim
1. A shunt for implantation between the anterior chamber of the eye and the epithelial-lined space through the frontal sinus bone of a patient for the treatment of glaucoma, comprising:
- a tube having a length sufficient to span the distance between the anterior chamber of the eye and the epithelial-lined space of the patient, the tube having an open anterior chamber end and a closed epithelial-lined space end;
a seal device associated with the tube between the anterior chamber and epithelial-lined space ends, for sealing a hole in the frontal sinus bone, and for anchoring the tube against movement from the frontal sinus bone;
a fluid pressure openable valve in the tube, the valve being located at or near the epithelial-lined space end of the tube such that when implemented the valve is within the epithelial-lined space, allowing for controlled flow of aqueous humor through the tube, the valve including a longitudinal slit in the tube; and
one or more ligature devices around the tube overlying or adjacent the slit wherein at least one ligature device overlies the slit so that adjustment of the one or more ligature devices adjusts fluid flow through the valve, the one or more ligature devices tighten the slit allowing less fluid to escape from the tube and drain from the anterior chamber.

Abstract
This invention provides a shunt for implantation between the anterior chamber of the eye and the epithelial-lined space through the frontal sinus bone of a patient for the treatment of glaucoma. The shunt includes a tube having a length sufficient to span the distance between the anterior chamber of the eye and the epithelial-lined space of the patient, the tube having an open anterior chamber end and a closed epithelial-lined space end, and a seal device associated with the tube between the anterior chamber and epithelial-lined space ends, for sealing a hole in the frontal sinus bone, and for anchoring the tube against movement from the frontal sinus bone. The shunt also includes a fluid pressure openable valve in the tube, located at or near the epithelial-lined space sinus end, allowing for controlled flow of aqueous humor through the tube when implanted. The invention also extends to a method of treating glaucoma in a patient by surgically implanting the shunt between the anterior chamber of the eye and the frontal sinus.

7. A shunt for implantation between the anterior chamber of the eye and an epithelial-lined space of a patient for the treatment of glaucoma, comprising:
-
a tube having a length sufficient to span the distance between the anterior chamber of the eye and the epithelial-lined space of the patient, the tube having an open anterior chamber end and an epithelial-lined space end; a seal device associated with the tube between the anterior chamber and epithelial-lined space ends to seal and anchor the tube against movement once implanted; an adjustable valve in the tube to control flow of aqueous humor through the tube when implanted, the valve including a longitudinal slit in the tube; and a plurality of ligature devices around the tube at the slit, at least one of the ligature devices overlying the slit such that adjustment of the at least one of the ligature devices adjusts fluid flow through the valve. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 26)

18. A shunt for implantation between the anterior chamber of the eye and the frontal sinus of a patient for the treatment of glaucoma, comprising:
-
a tube having a length sufficient to span the distance between the anterior chamber of the eye and the frontal sinus of the patient, the tube having a tube end and a valved frontal sinus end; a seal component on the tube spaced from the frontal sinus end to hold the tube in place in the frontal sinus; a slit extending longitudinally in the tube and located at the frontal sinus end, allowing for flow of aqueous humor through the tube when implanted; and a plurality of ligature devices around the tube at the slit to wherein at least one ligature device overlies the slit control flow through the slit. - View Dependent Claims (19, 20, 21, 22, 23, 24, 27)
