An atrial septal defect (ASD) is an abnormal hole (defect) in the wall (septum) between the heart’s upper chambers (atria). The hole might be as small as a pencil point or as large as the entire septum. The exact causes of an ASD are not known. Many ASDs close spontaneously in the first years of life.
The GORE® CARDIOFORM Septal Occluder is a minimally invasive device intended for the closure of an ASD using cardiac catheterization. It is a permanent implant consisting of a wire frame covered with a thin ePTFE membrane.
