US Patent 11382747 Device and method for controlling in-vivo pressure

A differential pressure regulating device is provided for controlling in-vivo pressure in a body, particular in a heart. The device may include a shunt being positioned between two or more lumens in a body, to enable fluids to flow between the lumens, and an adjustable flow regulation mechanism being configured to selectively cover an opening of the shunt to regulate the flow of fluid through the shunt in relation to a pressure difference between the body lumens. In some embodiments, a control mechanism coupled to the adjustable flow regulation mechanism may be provided to remotely activate the adjustable flow regulation mechanism.
