Claim 4:
5. The device of claim 1, further comprising:
an inner sleeve having a proximal region and a distal region having an outer diameter equal to an inner diameter of the sheath, the inner sleeve moveably disposed within the lumen of the sheath,
wherein the actuator is configured to be selectively actuated to modify the area of the opening of the second set of one or more openings of the sheath by moving the inner sleeve relative to the sheath by an incremental amount such that blood is permitted to flow between the first and second atria responsive to a pressure gradient across the interatrial septum via the first and second sets of one or more openings and the sheath lumen therebetween, at a blood flow rate corresponding with the area of the opening of the second set of one or more openings of the sheath.
