Sinus venosus atrial septal defect treatment device

Abstract

The sinus venosus atrial septal defect (“ASD”) treatment device includes has a generally tubular or funnel shaped configuration. A first end of the device can have a diameter that is less than a diameter of a second end of the device. The device can be inserted in the right upper right pulmonary vein PV. The second end of the device is configured to expand in a skirt-like configuration once the device is positioned in the right upper right pulmonary vein PV. In this manner, the device closes the upper sinus venosus hole and diverts anomalous pulmonary venous drainage into the left atrium.

1 . A sinus venosus atrial septal defect treatment device, comprising:
 a tubular body having opposed first and second open ends, the body being defined by:
 a proximal portion having an expandable peripheral wall, the expandable peripheral wall of the proximal portion including a balloon catheter locking system on an exterior surface thereof; 
 a distal portion having an expandable peripheral wall, the expandable peripheral wall of the distal portion including an expandable septal augmenter rim at an edge portion thereof; and 
 a central portion between the proximal portion and the distal portion, the central portion including an expandable peripheral wall.
