Abstract:
1. A device for relieving intraocular pressure, comprising: a microflow control system comprising at least one pressure-sensitive valve, where the at least one pressure-sensitive valve has a pressure threshold at which it changes from a first configuration to a second configuration, where one of the two configurations is an opened configuration and the other is a closed configuration, such that when in the open configuration fluid is allowed to pass through the at least one pressure-sensitive valve, and when in the closed configuration fluid is prevented from passing through the at least one pressure-sensitive valve; a protective hollow carrier tube having two opened ends though which fluid can pass, where the microflow control system is attached with and fitted inside the protective carrier tube; and a pair of foldable anchoring arms having rounded edges and opposingly attached with an exterior of the protective carrier tube, wherein each folding anchoring arm of the pair of foldable anchoring arms comprises as set of rounded arm tips to retain the device in as desired position within a patient's eye, such that a set of rounded arm tips is placed on each side of an eye wall of the patient; wherein the device is configured such that changes in intraocular pressure beyond a prescribed pressure threshold will cause the at least one pressure-sensitive valve of the device to change configurations, thereby allowing or disallowing fluid drain from the patient's eye.
