Abstract
The invention relates to a closure device (10) for closing an anatomical anomaly in the form of a vascular opening (80), such as patent ductus arteriosus, atrial septal defect, foramen ovale or ventricular septal defect, including a closure body (14) that extends at least within the vascular opening and wirelike, elastic locking members (30, 32, 34). In order to improve a fixation of the closure device and to preclude injuries, it is proposed that the locking members (30, 32, 34), on their free ends, be embodied spherically or in lentiform fashion or be provided with spherical or lentiform elements (40).
