MemoCarna^® Atrial Septal Defect (ASD) Occluder

MemoCarna® Atrial Septal Defect Occluder Details

Product Description

• MemoCarna® Atrial Septal Defect (ASD) Occluder with single hub

• The product is composed of a nickel titanium alloy stent, a stainless steel bushing and a polyester fiber membrane.

• The stent is made of medical nickel-titanium memory alloy wires and filled with the polyester fiber membrane, to be applied for the atrial septal defect.

• A stainless steel screw bushing used for fixing the nickel-titanium alloy wire on one end thereof, and the nut  of the steel screw bushing may match with the screw of the head end of the conveyor pushing rod.

Product Features

• Atrial Septal Defect Occluder adopts unique Dature-shape braiding technology, achieves faster endothelization with more flat disk after releasing and decreasing influences to blood flow.

• Atrial Septal Defect Occluder updated surface treatment technology, forming uniform and even oxide layer while  removing impurities. Nickle ions release is effectively reduced and delivery performance  is enhanced.

Indications for Use

• Suitablefor the secundum left-to-right shunt atrial septal defect (ASD) with the ASD diameter of ≥ 5mm and  ≤ 36mm and the increased right ventricular volume overload;

• The defect edge is ≥ 5mm distanced from the coronary sinus, the superior or inferior vena cava and the pulmonary vein, and is ≥ 7mm distanced from atrioventricular valve.

• Other cardiac abnormalities required for the surgery are not combined.

Product Highlights

• Well coordinated with delivery system, multi withdraw, release and antifatigue performance.

• After 3 months implantation, CARNA occluder positioned well, without residual shunt, smooth two disks surface without thrombus or neoplasms.

Product Advantages

• Adopt updated structure braiding technology, with advanced heat treatment technique,

• guarantee additional advantages:

• Effectively decreased nitinol ions release into human body.

• Accelerated endothelialization process, minimize thrombus risk.

• Single hub design reduce metal implantation and device-driven thrombus risk.
