Embodiment Construction

[0039] In accordance with the principles of the present invention, an implantable device for treating excessive intraocular pressure in an eye is provided. In preferred embodiments, the implantable device comprises a cavity and an elastic membrane disposed within the cavity, thereby creating a fluid pathway through the device. The elastic membrane is self-regulating to control the flow of aqueous humor from the anterior chamber of the eye through the pathway to a sink outside the eye (e.g., formed under the scleral flap or orbital fat space of the eye The flow rate of the filter bubble). According to one aspect of the present invention, the implantable device includes a localized constriction region disposed within the cavity to reduce the area of ​​the fluid pathway to increase fluid flow through the pathway Fluid resistance to flow. In an alternative embodiment, the implantable device comprises a circular passage such that the elastic membrane is positioned around the loca...

Abstract

A device (100) is provided for treating diseases that produce elevated intraocular pressures, such as glaucoma, wherein the device (100) includes a housing shell (101) defining a cavity (107) between a first end (102) and a second end (104) of the housing shell (101), and an elastic membrane (110) disposed within the cavity (107) to divide the cavity (107) into a fluidic channel (106) that permits a flow of fluid from the first end (102) to the second (104) end and a sealed cavity (112). The elastic membrane (110) deforms to change the volume of the sealed cavity (107) responsive to pressure fluctuations between the first and second ends (102, 104), thereby varying the fluidic resistance of the flow of fluid through the fluidic channel (106).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 728,022, filed September 6, 2018, which is hereby incorporated by reference in its entirety. This application is also related to U.S. Patent Application No. 15 / 612,988, filed June 2, 2017, which claims priority to U.S. Provisional Application No. 62 / 346,456, filed June 6, 2016 Interest, the entire contents of each of said applications are incorporated herein by reference. technical field [0003] The present application relates to a device for draining excess intraocular fluid to relieve intraocular pressure, for example for the treatment of glaucoma. Background technique [0004] Glaucoma affects approximately 70 million people worldwide and is a condition associated with high intraocular pressure caused by the production of excess intraocular fluid (aqueous humor). Aqueous humor is produced by the ciliary body at a rate of 2 μl / min to 3...
