Abstract:
A cardiac reinforcement device for constraining outward expansion of a heart during diastole, said device comprising:a jacket with a membrane for forming a right ventricular chamber and a separate left ventricular chamber on a single side thereof, wherein the jacket is adapted to wrap around a heart so that the right ventricular chamber is adjacent a right ventricle of the heart, and a left ventricular chamber is adjacent a left ventricle of the heart; a first bladder in fluid communication with the right ventricular chamber by a supply tube, wherein a first volume of liquid can flow between the first bladder and the right ventricular chamber; and a second bladder in fluid communication with the left ventricular chamber by a supply tube, wherein a second volume of liquid can flow between the second bladder and the left ventricular chamber; wherein adding or decreasing the first liquid volume or the second liquid volume will change the amount of pressure applied to the heart by the device.
