1. A method for treating regurgitation through a valve in a heart, the heart having an atrium fluidically coupled to a ventricle by the valve, the valve including at least two leaflets which coapt along a line of coaptation, the method comprising:

  • introducing percutaneously a medical device system into a patient'"'"'s heart to a vicinity of a gap within the line of coaptation of the valve, the medical device system comprising;

    a steerable guide catheter configured for delivery through the patient'"'"'s vasculature to the vicinity of the gap;

    a retractable sheath moveably disposed over a device comprising a frame sized to fit within a heart chamber and a pair of arms moveably coupled to the frame, the arms are structurally configured to move from a fluid flow-blocking position during a systole to a fluid flow-allowing position during a diastole in response to pressure changes occurring between the systole and the dystole;

    using the guide catheter to position the device within the gap along the line of coaptation;

    retracting the sheath to release the blocker from compressive forces maintaining the device in the delivery configuration;

    expanding the device after positioning the device along the line of coaptation; and

    retracting the catheter and the sheath from the heart.
