1. An apparatus for coupling to an atrial shunt for regulating blood pressure between a patient'"'"'s left atrium and right atrium, the apparatus comprising:

  • a catheter having a proximal region and a distal region, the distal region sized and shaped to be advanced to the patient'"'"'s atrial septum;

    one or more latching legs disposed at the distal region of the catheter, the one or more latching legs having a hook portion and a ramp portion disposed proximal to the hook portion;

    a ring coupled to the one or more latching legs;

    an actuator disposed at the proximal region of the catheter, the actuator configured to move the ring between a first position, where the ring contacts a first section of the ramp portion such that the one or more latching legs extend radially outward, and a second position, where the ring contacts a second section of the ramp portion such that the one or more latching legs move radially inward; and

    a ring base coupled to the ring and the actuator, wherein the actuator causes the ring base to move the ring between the first position and the second position.
