First Claim
Patent Images
1. An acoustic streaming valve arrangement for inducing flow in a glaucoma drainage device, comprising:
- a valve portion configured to selectively inhibit fluid flow between a fluid inlet and a fluid outlet, wherein the valve portion comprises;
a boss portion including a seat; and
a flexible portion, wherein the flexible portion selectively and sealingly engages with the boss portion to selectively inhibit fluid flow;
a selectively vibrating flow generator having a sharp edge; and
a driving device configured to selectively vibrate the flow generator to create a streaming fluid flow in a direction away from the sharp edge and disengage the flexible portion from the boss portion to open the valve portion to allow fluid flow between the fluid inlet and the fluid outlet.

7. An implantable glaucoma drainage system, comprising:
-
an inlet passageway and an outlet passageway; and a valve portion disposed between the inlet and outlet passageways to regulate the passage of fluid from the inlet passageway to the outlet passageway, the valve portion comprising an acoustic streaming valve arrangement configured to open or close the valve portion, the valve portion further comprising a flexible portion deflectable from a neutral condition to a displaced condition, the valve portion allowing passage of fluid when the flexible portion is in a deflected condition and inhibiting passage of fluid when the flexible point is a neutral condition, the inhibiting caused by sealingly engaging the flexible portion with a boss portion. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A method comprising:
-
implanting a flow system in an eye of a patient; and activating an acoustic streaming valve arrangement forming a part of the flow system to open or close a valve portion to inhibit or allow drainage fluid to flow through the flow system, wherein opening the valve portion includes causing it to disengage from a boss portion. - View Dependent Claims (17, 18, 19)
