Abstract
A device for the percutaneous transluminal repair of septal defects is disclosed. The device comprises first and second expandable occluders fastened to each other, each occluder including a framework having a central hub with elongated struts radiating therefrom. The struts are constructed such that they have a resistance to fatigue that exceeds the maximum fatigue stresses to which the struts will be subjected over a prolonged period in vivo. As such, the device exhibits a significantly decreased likelihood of metal fatigue failures after prolonged exposure in vivo.
