Abstract:
1. An intraocular pressure (IOP) control valve for implantation in an eye of a patient, comprising: a housing including a fluid inlet and a fluid outlet; and a corrugated membrane anchored within the housing to form a reference chamber on a first side of the corrugated membrane and a fluid flow channel on a second opposing side of the membrane, the reference chamber having a reference chamber pressure representative of atmospheric pressure, the fluid flow channel selectively increasing and decreasing in size to permit fluid to flow from the fluid inlet to the fluid outlet, the corrugated membrane configured to affect flow through the fluid flow channel from the fluid inlet to the fluid outlet by deflecting in response to pressure differentials of the reference chamber pressure and the fluid flow channel pressure acting on the opposing sides of the corrugated membrane.
