An expandable device adapted for percutaneous delivery into a membrane of a patient's heart, the device comprising:
- a retainer comprising first and second anchors adapted to contact, respectively, a first side and a second side of the membrane;
- a first shunt removably attachable to the retainer, the first shunt being adapted to permit blood to flow across the membrane at a first flow rate;
- a second shunt removably attachable to the retainer, the second shunt being adapted to permit blood to flow across the membrane at a second flow rate;
- wherein the first and second shunts are adapted to be alternatively connected to the retainer, wherein the first and second shunts, respectively, are configured to be percutaneously delivered to the retainer after the retainer is implanted into the membrane of the patient's heart.
