1. An interatrial shunt for regulating blood volume distribution configured for placement in an interatrial septum between a patient's left atrium and the patient's right atrium, the interatrial shunt comprising:
an hourglass-shaped anchor having a first region, a second region, a neck region joining the first region to the second region, the hourglass-shaped anchor configured to transition from a collapsed delivery state to an expanded deployed state in which the first region extends into the patient's left atrium, the second region extends into the patient's right atrium, and the neck region is disposed at the interatrial septum, the expanded deployed state exhibiting the hourglass-shape; and
an expanded-polytetrafluoroethylene (ePTFE) conduit affixed to the hourglass-shaped anchor and defining a lumen that permits blood to flow across the interatrial septum via the interatrial shunt, wherein the lumen at a narrow portion of the neck region has a diameter of 4-6 mm in the expanded deployed state, and wherein the first region is configured to protrude 2.5-7 mm into the left atrium and the second region is configured to protrude 5-9 mm into the right atrium in the expanded deployed state.
