MemoPart™ Patent Ductus Arteriosus (PDA) Occluder Details
Product Description
MemoPart™ PDA Occluder is a self-expandable device made from nitinol wire mesh. Aretention skirt on the aortic side provides secure positioning in the ampulla of the ductus. As the occluder is implanted, it expands outward and the wires push against the wall of the ductus. Polyester fabric is sewn into the occluder with polyester thread.The fabric induces thrombosis that closes the communication.
Product Features
Modified rigidity and flexibility for different type of occluders - balanced stiffness of Patent Ductus Arteriosus Occluder (PDAO) ensures the optimal occlusion performance.
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 Patent Ductus Arteriosus Occluder (PDAO) helps with earlier endothelialization to minimize the risk of thrombosis.
Indications for Use
The MemoPart™ Patent Ductus Arteriosus (PDA) Occluder can be used for the nonsurgical closure of apatent ductus arteriosus (PDA) in the percutaneous, transcatheter therapy.
