HASDO™ ASD occluder for Hybrid procedure


Kewei Rising is a pioneer in the innovation of Hybrid ASD device. Since the first design in 2003,HASDO ™ ASD occluder and delivery system have been improved greatly. The last generation of HASDO ™ is non-tip, no screw in design.



What is Hybrid ASD procedure?

The Hybrid ASD procedure combines approaches of surgery and transcatheter intervention. The therapy is operated via a 3cm cut on the right anterior chest,under the guidance of TEE or TTE, to close the defect with a special designed occluder via a short and straight tube. Paitients are generally allowed to check out 2 or 3 days after the procedure.

Why does Kewei Rising promote HASDO ™ Occluder and Hybrid Procedure?

Although percutaneous interventional closures are well-accepted in the treatment of congenital heart defects, it may be associated with an increased risk and difficulties due to limited vascular access or a very tortuous catheter course. In these cases, combining operative and interventional approaches with direct puncture of the heart or the great vessels may facilitate the implantation of even large devices.Furthermore,in most cases, cardiopulmonary bypass can be omitted when doing a hybrid procedure.

What is the advantage of Hybrid procedure comparing with interventional closure?

1) With the straight and short delivery system, the placement of occluders become easier,safer and precise. As a result, some extra large and edge-absence cases can be cured with Hybrid procedure.


2) It is free from the limit of vascular access. That benefits those baby patients of ASD.

3) The HASDO™ occluder is of non-tip design. Without the stainless tip and screw, complications like embolism, hemolysis are reduced.
