Abstract
A device for precise control of blood flow across an interatrial septum is provided. The device includes a sheath having a first set of openings disposed within a first atrium while a second set of openings is disposed within a second atrium. An actuator may be actuated to move an inner sleeve within the sheath to modify the area of second set of openings to permit blood to flow between the first and second atria responsive to a pressure gradient across the interatrial septum via the first and second openings at a blood flow rate corresponding with the area of the second set of openings of the sheath. In addition, the patient's hemodynamics responsive to the shunting of blood across the interatrial septum at each incremental area of the opening may be monitored for selecting a specific sized implantable interatrial shunt for the patient.
