Patent ID: 8753305

Claim:
An intraocular pressure (“IOP”) control system for implantation in an eye of a patient to provide drainage from an anterior chamber of the eye to a drainage site at the eye, comprising: a drainage tube with a first end configured to be located in the anterior chamber and a second end, the drainage tube being configured to convey fluid from the anterior chamber toward the drainage site to relieve intraocular pressure; 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 system; and an override pressure relief system comprising: an override pressure relief line with a first end fluidly coupled to the drainage tube and a second end configured to be located at the drainage site; and an override pressure relief valve coupled to the override pressure relief line, the override pressure relief valve configured to operate when intraocular pressure increases above preset values and the valve system is not sufficiently responsive.
