Abstract
The invention relates to a medical device, in particular a stent, having a radially self-expandable lattice structure () which is tubular at least in some sections and which is made of a single wire (), which is interwoven with itself and which comprises a core material () which is visible under X-ray and a superelastic jacket material () and forms meshes () of the lattice structure (). The invention is characterized in that a plurality of meshes () arranged directly adjacently in the circumferential direction of the lattice structure () form a mesh ring (), and the lattice structure (), in a fully self-expanded state, has an expansion diameter Dexp, the mesh ring () having a mesh number n, and the core material () 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.
