The frame of the occluder uses Nitinol wires as material that shaped into two discs. A waist that fits the size of the defect connects the two discs. Three polyester fabrics insert to help close the hole and provide a foundation for growth of tissue over the occluder after placement. Low profile and weill shaping are considered as two essential parameters in the design of Amender™ occluder.

Intergal Weaving technology is adopted in small and middle sizes Amender™ ASD occluders. ASD occluder over 30mm where a stick-out is needed functionally, are weaved in the traditional way.
