The Role of CardioSEAL and Starflex Devices in Atrial Defect Occlusion.
The CardioSEAL and Starflex implants (Nitinol Medical Technologies, Boston, MA) are self-expanding, double-umbrella septal occluders designed to close small to moderate secundum atrial septal defects (ASDs), the latter having a self-centering mechanism. Overall, successful clinical defect occlusion occurs in more than 90% of patients following implantation. In this article, we discuss the development, design issues, technique of implantation, and clinical results pertinent to these new devices.
