Abstract
An asymmetric device for regulating blood volume distribution across a patient's atrial septum having a first expandable end region and a second expandable end region. The first expandable end region is transitionable from a contracted delivery state to an expanded deployed state in which the first expandable end region extends into the patient's left atrium and an inlet end of the first expandable end region is in a first plane. The second expandable end region is transitionable from a contracted delivery state to an expanded deployed state in which the second expandable end region extends into the patient's right atrium and an outlet end of the second expandable end region is in a second plane, such that the first plane intersects the second plane. The device further includes a neck region joining the first expandable end region to the second expandable end region, wherein the neck region is sized and shaped for placement in the patient's atrial septum.
