Abstract
Systems and methods for delivering a device for regulating blood pressure between a patient's left atrium and right atrium are provided. The delivery apparatus may include a first catheter, a hub having one or more engagers disposed thereon configured to releasably engage with a first expandable end of the shunt in a contracted delivery state within a lumen of a sheath, and a second catheter extending through a center lumen of the first catheter and the hub, wherein the first catheter, the hub, and the second catheter are independently moveable relative to the sheath. 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.
