Atrial Septal Closure Occlusion Device

MemoPart™ ASD Occluder is a self-expanding double-disc nitinol mesh occlusion device. The 2 discs are connected by a short waist that relates to the defect size. Polyester fabric is securely sewn to each disc to increase occlusion. The device is visible under X-ray.

Product Features

Modified rigidity and flexibility for different type of occluders - greater stiffness of Atrial Septal Defect Occluder (ASDO) offers excellent supporting force for big disks.

Uniform and smooth oxide film on nitinol wire effectively prevents from the release of nickel ion to guarantee the great biocompatibility and long-term safety.

The hubless design of Atrial Septal Defect Occluder (ASDO) helps with earlier endothelialization to minimize the risk of thrombosis.

Indications for Use

The MemoPart™ ASD Occluder is a percutaneous, transcatheter, atrial septal defect closure device intended for the occlusion of atrial septal defects （ASD）in secundum position or patients who have undergone a fenestrated Fontan procedure and who require closure of the fenestration.

Patients indicated for ASD closure have echocardiographic evidence of ostium secundum atrial septal defect and clinical evidence of right ventricular volume overload（i.e.,1.5:1 degree of left-to-right shunt or RV enlargement ）.
