APPARATUS AND METHODS FOR TREATING EXCESS INTRAOCULAR FLUID
First Claim
1. An ocular drainage system for the treatment of excess fluid within an eye, the system comprising:
- a housing configured to be implanted on or within an exterior layer of the eye;
at least one deformable tube disposed within the housing, the deformable tube having a lumen and a hydraulic resistance; and
a disk rotatably mounted within the housing, the disk arranged to selectively rotate within the housing to apply a compressive force to the deformable tube to thereby adjust the hydraulic resistance.

Abstract
An ocular drainage system is provided for treating diseases that produce elevated intraocular pressures, such as glaucoma, wherein the system includes an implantable device and an external control unit. The implantable device includes a non-invasively adjustable valve featuring at least one deformable tube and a disk rotatably mounted within a housing, such that rotation of the disk using the external control unit causes the disk to apply a selected amount of compression to the deformable tube, thereby adjusting the fluidic resistance of the deformable tube and regulating the intraocular pressure.

31. A method of reducing intraocular pressure within an eye, the method comprising:
-
providing an implantable device including a housing, at least one deformable tube disposed within the housing and a disk rotatably mounted within the housing, the disk arranged to selectively rotate within the housing to apply a compressive force to the deformable tube to thereby adjust an fluidic resistance of the deformable tube; implanting the implantable device on or within an exterior layer of the eye so that the deformable tube is in communication with aqueous humor in an anterior chamber of the eye; non-invasively coupling the disk within the implantable device to an external control unit; and moving the control unit to non-invasively adjust an angular orientation of the disk within the implantable device, thereby adjusting fluidic resistance of the deformable tube. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
