Abstract (en)
[origin: WO2020126721A1] The invention relates to a medical device, in particular a stent, having a radially self-expandable lattice structure (10) which is tubular at least in some sections and which is made of a single wire (11), which is interwoven with itself and which comprises a core material (11a) which is visible under X-ray and a superelastic jacket material (11b) and forms meshes (12) of the lattice structure (10). The invention is characterised in that a plurality of meshes (12) arranged directly adjacently in the circumferential direction of the lattice structure (10) form a mesh ring (13), and the lattice structure (10), in a fully self-expanded state, has an expansion diameter Dexp, the mesh ring (13) having a mesh number n, and the core material (11a) having a core diameter dKern, and the following being true for the core diameter dKern: dKern = f ∙ (Dexp / n), with the following being true for a visibility factor f: 0.05 ≤ f ≤ 0.08.
