Abstract: A valve assembly (10) configured to maintain fluid flow therethrough at a constant flow rate. The valve assembly (10) including a flexible flow control member (50) defining an inner fluid chamber (90) within the flexible flow control member (50) and an inlet opening (56) to the inner fluid chamber (90). An outer fluid chamber (92) is defined between the flexible flow control member (50) and an inner surface (74) of a valve housing (20). The flexible flow control member (50) is configured to flex inward and shrink the inner fluid chamber (90) in response to a pressure decrease in the inner fluid chamber (90) relative to the outer fluid chamber (92) resulting from an increase in an inlet flow rate to maintain an outlet flow rate from the valve assembly (10) at the constant flow rate.

Abstract: Disclosed is a system including a flow regulating system. The flow regulating system may assist in ensuring a selected pressure within an inlet volume. The flow regulator may be included in a shunt assembly.

Abstract: Disclosed is a control system for a shunt system implantable in a subject. The control system may operate a selected portion of the shunt system, such as a flow control. The control system may operate the shunt system with a closed feedback loop based upon selected sensor input to achieve selected or optimal outcomes.

Abstract: Disclosed is a valve assembly operable to selectively control a flow or passage of a fluid. The valve assembly may be applied to any appropriate mechanism such as a hydrocephalus shunt, fluid draining sewage system, or tank holding system. The valve assembly disclosed may include a selected profile for various applications.
