Abstract: An apparatus is provided for draining aqueous humor from an eye for reducing intraocular pressure. The draining apparatus comprises a tube defining a passage for fluid flow between an inlet end and an outlet end. An outlet assembly contacts the conjunctival layer externally of the eyeball. The outlet assembly comprises a housing in fluid communication with the outlet end of the tube and having an aperture for allowing egress of aqueous humor onto the external ocular surface. A resistive component is disposed in the housing for providing resistance to a flow of aqueous humor. A pair of tabs project outwardly and are adapted to be disposed subconjunctivally for securing the draining apparatus relative to the eyeball.

Abstract: An apparatus for reducing/stabilizing intraocular pressure is provided. A tube extends from an inlet end in fluid communication with an anterior chamber of the eye, to direct an aqueous humor flow from the anterior chamber to an outlet end in fluid communication with a cavity, defined by a housing, for receiving the aqueous humor. A flow control device is operably engaged with the housing, and is configured to control the flow of the aqueous humor, via a conduit defined thereby and extending from the cavity, to a location away from the anterior chamber. The conduit is dilatable in response to the intraocular pressure being above a preselected pressure, to increase the flow or to decrease resistance to flow of the aqueous humor through the conduit to the drainage site and to reduce the intraocular pressure to no greater than the preselected pressure. Associated apparatuses and methods are also provided.
