1. A device for treating a heart condition in a patient, the device comprising:

  • a body comprising an inner lumen defining at least one passageway with a first end and a second end, wherein the body has a collapsed configuration with a reduced diameter for passing through a catheter, and an expanded configuration with a larger diameter;

    a first flange and a second flange positioned on either end of the body, wherein both the first and the second flange have a collapsed tubular configuration with a first portion joining the body at a first end of the first portion and a second portion joining the first portion at a second end of the first portion, and an expanded flange configuration with the first portion of both flanges forming a first exterior face and the second portion of both flanges forming a second exterior face,wherein, in the expanded configuration, the first and second flanges are adapted for mounting the body in an opening in the patient'"'"'s atrial septum each with the first exterior face contacting the atrial septum, and the second exterior face facing away from the atrial septum, and wherein, in the collapsed configuration, both exterior faces of the first and second flanges extend away from one another causing the first and second flanges to lengthen and resume the tubular configuration; and

    at least one valve disposed inside the passageway, the valve positioned closer to a central portion of the passageway than the first or second ends of the passageway, along a longitudinal axis of the passageway,wherein the at least one valve is adapted to open and allow blood flow through the passageway from the left atrium to the right atrium to thereby reduce the left atrial pressure when the patient'"'"'s left atrial pressure exceeds the patient'"'"'s right atrial pressure by a predetermined amount and prevent flow from the right atrium to the left atrium when the right atrial pressure exceeds the left atrial pressure.
