1. A shunt for regulating blood pressure between a patient's left atrium and right atrium, the shunt comprising:
a shunt conduit configured to be implanted at an atrial septum of the patient to dilate an opening in the atrial septum, the shunt conduit having an outer surface along a length greater than a thickness of the atrial septum, the shunt conduit configured to transition between a collapsed state suitable for percutaneous delivery and an expanded state when deployed across the patient's atrial septum such that the shunt conduit has a smallest diameter where the outer surface traverses the atrial septum and has a larger diameter at the outer surface where an end region of the shunt conduit extends into an atrium, wherein the shunt conduit has a diabolo shape and is configured to be collapsible after implantation.
