An medical implantable occlusion device (100) is disclosed having a collapsed state and an expanded state and comprising a braiding (101) of at least one thread, and a distal end (102) comprised of said braiding. The distal end comprises loops (103, 104, 204, 304) formed by loop strands (105, 106, 206, 306) of the at least one thread, wherein, at least in said expanded state, each loop strand has a curved shape and extends away from a centre point (117) of the distal end, whereby an apex point (107, 108, 208, 308) of each of the loop strands corresponds to the turning point of the curved shape and to the point of each of the loop strands being arranged closest to the centre point. At least one of the loop strands is displaced from the centre point by a centre distance (109, 110, 210, 310), and the apex point lie at a distance from a periphery (113) of the distal end.
