The invention concerns a medical device, in particular a flow diverter, having a radially self-expandable lattice structure () which is tubular at least in some regions and which is composed of a plurality of interwoven individual wires () which form meshes () of the lattice structure (), wherein at least some of the individual wires () have an X-ray visible core material () and a superelastic mantle material (), wherein a plurality of directly adjacent meshes () in the circumferential direction of the lattice structure () form a mesh ring (), wherein in a fully self-expanded state, the lattice structure () has an expansion diameter D, the mesh ring () has a mesh number n, and the core material () has a core diameter d, and wherein for the core diameter d, the following holds: 2. The medical device as claimed in claim 1 ,characterized in that{'sub': 'exp', '#text': 'the expansion diameter Dis 2.5 mm to 8 mm.'}3. The medical device as claimed in one of the preceding claims claim 1 ,characterized in that{'b': '10', '#text': 'a braiding angle α of the lattice structure () is between 70° and 80°, in particular 75°.'}4. The medical device as claimed in one of the preceding claims claim 1 ,characterized in that{'b': '11', 'sub': 'wire', 'claim-text': [{'sub': ['exp', 'wire'], '#text': 'in the case of an expansion diameter Dof 2.5 mm to 4.5 mm: 30 μm≤d≤46 μm, and'}, {'sub': ['exp', 'wire'], '#text': 'in the case of an expansion diameter Dof more than 4.5 mm to 8 mm: 46 μm≤d≤65 μm.'}], '#text': 'the wire () has a wire diameter d, which is'}5. The medical device as claimed in one of the preceding claims claim 1 ,characterized in that{'b': '11', 'i': 'b', '#text': 'the mantle material () of the wire has a thickness which is at least 10 μm, in particular at least 15 μm, in particular 10 μm to 20 μm.'}6. The medical device as claimed in one of the preceding claims claim 1 ,characterized in that{'b': ['11', '11'], 'i': 'a', '#text': 'the volume of the core material () takes up a ...
