DEVICE AND METHOD FOR CONTROLLING IN-VIVO PRESSURE
First Claim
1. A device for reducing elevated left atrial pressure, the device comprising:
- a shunt element configured to define a passageway between the left atrium and right atrium through the atrial septum,said shunt element comprising a valve element configured to regulate blood flow between the left atrium and the right atrium through the shunt element, the valve element being constantly ajar; and
a support structure configured to support the shunt element in a hole through the atrial septum.

Abstract
A differential pressure regulating device is provided for controlling in-vivo pressure in a body, and in particularly 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.
