1. An apparatus for delivering a shunt to an atrial septum of a patient, the apparatus comprising:
a catheter having a lumen and an exterior surface having a first diameter;
a cap coupled to a distal end of the catheter, the cap comprising an exterior surface having a second diameter less than the first diameter and one or more windows disposed on the exterior surface of the cap;
one or more latching legs disposed within the lumen of the catheter, each of the one or more latching legs having a hook portion, the one or more latching legs configured to move between a first position, where the hook portion protrudes through the one or more windows of the cap, and a second position, where the one or more latching legs move radially inward within the cap to release the shunt; and
a pull cord disposed within the catheter and configured to move the one or more latching legs between the first position and the second position,
wherein, in the second position, the hook portion of the one or more latching legs is completely disposed within the cap and does not extend beyond the second diameter of the cap.
