Patent ID: 11395644

Abstract:
Devices and methods for treating a sinus venosus atrial septal defect. A treatment device may have a tubular shape and may be configured to be arranged to provide a conduit between an upper right pulmonary vein (PV) and a left atrium (LA). The device may have a proximal portion comprising a flexible mesh configured to anchor within the LA, a distal portion comprising a flexible mesh configured to anchor within the target PV, and a central portion having a plurality of elongate parallel bars. A method for treating a sinus venosus atrial septal defect may include percutaneously advancing the device through the femoral vein and inferior vena cava (IVC), and into the right atrium (RA). The method may include creating a trans-septal opening, passing the device through the opening into the LA, and toward the upper right PV to treat the defect.
