Basic information

     The company's patent ductus arteriosus occluder and atrial defect occluder are one of the few occluder products that were first developed and produced in China. The research and development project was established in June 2003. The first trial production registrations were launched on December 27, 2004 and September 20, 2005. Both products were converted to quasi-production registrations on March 6, 2007. So far, more than ten products have been registered. Year. This laid a solid foundation and accumulated rich experience for us to develop ventricular septal defect occluders. In order to meet the needs of interventional treatment of ventricular septal defect, we developed a ventricular septal defect occluder based on the successful development of two previous occluder products.

     The human ventricular septum refers to the septal tissue that separates the left and right ventricles. Depending on whether the ventricular septal defect occurs in the muscular part of the ventricular septum or the membranous part after the patient is born, it is also called muscular ventricular defect or membranous ventricular defect. Therefore, in order to meet the needs of interventional sealing treatment, ventricular septal defect sealing devices are also divided into two models: muscular and membranous. The product is woven from nickel-titanium alloy wire and is in the shape of a double-umbrella bottle plug, connected by a short waist. It is filled with PET polyester non-woven fabric and is used to treat ventricular septal defects.

Performance advantages

This product consists of plugs, ends, end nuts, bluff bodies and sutures. The network plug is made of Ni-Ti memory alloy material that meets the standard of GB24627 "Nickel-Titanium Shape Memory Alloy Processing Materials for Medical Devices and Surgical Implants", and the end and end nut are made of stainless steel that meets the standard of GB4234 "Stainless Steel for Surgical Implants" 》Made of standard 00Cr18Ni14Mo3 material, the bluff body is made of PET (COC6H4COOCH2CH2O) polyester non-woven fabric, and the suture is made of uncoated multi-strand polyester non-absorbable surgical suture that meets the YY0167 "Non-absorbable surgical suture" standard. The product is delivered to the ventricular septal defect through a medical and surgical delivery system. Relying on its shape memory properties and elasticity, the product is radially supported at the defect to close the abnormal shunt and achieve sealing treatment of the ventricular septal defect.

Scope of application

This product is suitable for sealing ventricular septal defects in congenital heart disease.
