Claim 26:
27. A method for controlling of blood flow across a patient's interatrial septum, the method comprising:
creating a puncture through the patient's interatrial septum;
delivering a sheath across the puncture such that a first set of one or more openings of the sheath is disposed within a first atrium of the patient a second set of one or more openings of the sheath is disposed within a second atrium of the patient, and a proximal region of the sheath extends external to the patient's body;
permitting blood to flow between the first and second atria responsive to a pressure gradient across the interatrial septum via the first and second set of one or more openings and a lumen of the sheath;
modifying an area of an opening of the second set of one or more openings by selectively actuating an actuator operatively coupled to the proximal region of the sheath, such that blood is permitted to flow between the first and second atria via the first and second set of one or more openings and a lumen of the sheath at a modified blood flow rate; and
selecting an interatrial shunt for implantation in the patient's interatrial septum based on the modified area of the opening of the second set of one or more openings.
