1. A shunt for regulating blood pressure between a patient'"'"'s left atrium and right atrium, the shunt comprising:
- a diabolo-shaped stent comprising a plurality of sinusoidal rings interconnected by longitudinally extending struts, the stent configured to transition between a collapsed state suitable for percutaneous delivery and an expanded state when deployed across a patient'"'"'s atrial septum; and
a tissue valve disposed across the stent, the tissue valve configured to shunt blood flow from the left atrium to the right atrium when subjected to a predetermined pressure differential.

Abstract
A device for regulating blood pressure in a heart chamber is provided. The device includes a shunt positionable within a septum of the heart. The shunt is designed for enabling blood flow between a left heart chamber and a right heart chamber, wherein the flow rate capacity of the device is mostly a function of pressure in the left heart chamber.
