Abstract
Systems for delivering a device for regulating blood pressure across a patients atrial septum are provided. The delivery apparatus may include a first catheter, a hub having one or more engagers disposed thereon, the one or more engagers configured to releasably engage with a first expandable end of the shunt in a contracted delivery state within a lumen of a sheath, and an 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, increase cardiac output, increase ejection fraction, relieve pulmonary congestion, and lower pulmonary artery pressure, among other benefits. The inventive devices also may be used to treat subjects having heart failure, pulmonary congestion, or myocardial infarction, among other pathologies.
