MemoPart™ Ventricular Septal Defect (VSD) Occluder Detail

Product Description

MemoPart™ Ventricular Septal Defect (VSD) Occluder is a self-expanding double-disc nitinol mesh occlusion device.The 2 discs are connected by a short waist which corresponds to the defect size. Polyester fabric is securely sewnto each disc to secure the occlusion. The device is visible under X-ray.

Product Features

Modified rigidity and flexibility for different type of occluders - less stiffness of Ventricular Septal Defect Occluder (VSDO) reduces the holding force to minimize the risk of third degree atrioventricular block.
Different waist lengths of Ventricular Septal Defect (VSD) Occluders minimize the negative impact of compress force to the patients.
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 Ventricular Septal Defect Occluder (VSDO) helps with earlier endothelialization to minimize the risk of thrombosis.

Indications for Use

Membranous VSD Occluder

The MemoPartTM Membranous VSD Occluder is used for minimally invasive transcatheter closure of perimembranous ventricular septal defects.

Muscular VSD Occluder

The MemoPartTM Muscular VSD Occluder is indicated for use in patients with a complex ventricular septal defect (VSD) of significant size to warrant closure (large volume left-to-right shunt, pulmonary hypertension,and/or clinical symptoms ofcongestive heart failure) who are considered to be at high risk for standard transatrial or transarterial surgical closure based on anatomical conditions and/or based on overall medical condition.
