  • Patent number: RE46705
    Abstract: A self-expanding occlusion device for occluding an atrial auricula in the heart of a patient includes a braiding of thin wires or threads given a suitable profile form by means of a molding and heat treatment procedure. The occlusion device includes a proximal retention area, a distal retention area and a center section. The occlusion device holds securely in the atrial auricula of a patient in its expanded and implanted state without damaging the tissue of the patient's heart. The proximal retention area has a flanged area which positions at the inner walls of the atrial auricula when the occlusion device is in an expanded state in the atrial auricula to be occluded, and forms a force-fit connection with the inner walls of the atrial auricula, thus holding the implanted and expanded occlusion device in the atrial auricula, whereby the distal retention area closes the opening in the atrial auricula.
