the support structure or lattice structure 110 of a stent 100 the invention here is not restricted to the design of the lattice structure 110 illustrated in fig1 instead the invention can comprise all stent structures that have struts and in which the longitudinal sections have at least one directional component that runs in the radial circumferential direction of the stent this refers to those longitudinal sections 220 that as shown in fig1 do not run parallel to the longitudinal axis 150 of stent 100 this thus refers to longitudinal sections 220 that obviously run in a radial circumferential direction but also to the longitudinal sections that run obliquely relative to the longitudinal axis since these longitudinal sections have also a directional component that runs perpendicular to the longitudinal axis it is thus evident in fig2 that the surfaces of the strut facing the outside of the stent that is the mural surfaces that that contact the vascular wall 210 do not have any curvature in the cross section shown this means that these surfaces are curved only in one direction specifically about longitudinal axis 150 in the stent according to the invention curvature of the mural strut surfaces is not affected about axes that are perpendicular to longitudinal axis 150 the invention is made clear in particular by a comparison of the cross sectional shape of the strut in fig3 and.
