Atrial Septal Closure Occlusion Device

MemoCarna® Atrial Septal Defect (ASD) Occluder with a single hubinput:
output:A polyester fiber membrane, a stainless steel bushing, and a nickel titanium alloy stent comprise the product.input:
output:The stent is composed of medical nickel-titanium memory alloy wires and is filled with a polyester fiber membrane. It is intended for the treatment of an atrial septal defect.input:
output:A stainless steel screw bushing is employed to secure the nickel-titanium alloy wire at one end of the device. The nut of the screw bushing may be compatible with the screw on the head end of the conveyor pushing rod.



Product Specifications



The Atrial Septal Defect Occluder utilizes a distinctive Dature-shape braiding technology, which results in a more flat disk and faster endothelization after release, while simultaneously reducing the impact on blood flow.input:
output:The surface treatment technology of the Atrial Septal Defect Occluder has been updated to create a uniform and even oxide layer while simultaneously removing impurities. The release of nickel ions is significantly diminished, and the delivery performance is improved.input:
output:Useful indicationsinput:
output:
Suitable for the secundum left-to-right shunt atrial septal defect (ASD) with an ASD diameter of ≥ 5mm and ≤ 36mm, as well as the increased right ventricular volume overload.The defect edge is ≥ 5mm from the coronary sinus, the superior or inferior vena cava, and the pulmonary vein, and is ≥ 7mm from the atrioventricular valve.input:
output:Other cardiac abnormalities that necessitate surgery are not combined.input:
output:Product Highlightsinput:
output:Well-integrated with the delivery system, demonstrating antifatigue, multi-withdrawal, and release capabilities.input:
output:The CARNA occluder was well-positioned after three months of implantation, with no residual shunt and a smooth surface of two disks that were free of thrombus and neoplasms.
