Bubble-Driven IOP Control System
First Claim
1. An IOP control system for implantation in an eye of a patient to provide drainage from an anterior chamber of the eye to a drainage location at the eye, comprising:
- a drainage tube with a first end configured to be located in the anterior chamber of an eye and a second end, the tube being configured to convey fluid from the anterior chamber toward the drainage location to relieve IOP; and
a valve system in fluid communication with the drainage tube and configured for implantation in the eye, the valve system being arranged to control drainage flow through the drainage tube between the anterior chamber and the drainage site, the valve system being configured to control fluid flow using an electrolysis process.

Abstract
An intraocular pressure control system for implantation in an eye of a patient to provide drainage from an anterior chamber of the eye to a drainage location at the eye includes a drainage tube and a valve system arranged to control drainage flow between the anterior chamber and the drainage site, the valve system being configured to control fluid flow using an electrolysis process and closed loop feedback from pressure sensors able to determine: flow rate, TOP, bleb pressure, and internal valve pressure.

22. An IOP control system for implantation in an eye of a patient to provide drainage from an anterior chamber of the eye to a drainage location at the eye, comprising:
-
a drainage tube with a first end configured to be located in an anterior chamber of an eye, the tube being configured to convey fluid from the anterior chamber; a first sensor configured to detect pressure in the anterior chamber; a second sensor configured to detect atmospheric pressure; a third sensor configured to detect pressure at the drainage site; a valve system in fluid communication with the drainage tube and configured for implantation in the eye, the valve system being arranged to control drainage flow through the drainage tube between the anterior chamber and the drainage site; and a processor in communication with and configured to receive data from the first, second, and third sensors, the processor being configured to control the valve system based on the received data to maintain desired pressures in the anterior chamber and at the drainage site. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A method performed by an IOP control system that drains fluid from an anterior chamber of the eye to a drainage location of the eye, comprising:
-
detecting pressure within an anterior chamber of the eye; detecting pressure at a drainage location of the eye; determining whether to adjust drainage fluid flow based on the detected pressures by comparing the detected pressures in both the anterior chamber and the drainage location to preestablished acceptable pressures or pressure profiles as a function of time; and adjusting drainage fluid flow from the anterior chamber using a valve system to achieve pressures in both the anterior chamber and the drainage location corresponding to the acceptable pressures or pressure profiles as a function of time. - View Dependent Claims (30, 31, 32)
