Abstract
A device for regulating blood pressure between a patient's left atrium and right atrium, and apparatus for delivery the device, are provided. The delivery apparatus may include one or more latching legs, a release ring, a pull chord, and a catheter wherein the latching legs are configured to engage the device for delivery. The inventive devices may reduce left atrial pressure and left ventricular end diastolic pressure, and may increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices may be used, for example, to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies.
