    摘要: Stent, as well as a method and device for fabricating the stent, wherein the stent has a tubular lattice structure comprising individual struts and at least one strut of which at least one longitudinal section runs with at least one directional component in the radial circumferential direction of the stent, wherein the surface of the longitudinal section facing the outside of the stent is curved only about the longitudinal axis of the stent. According to the invention, the surface of longitudinal section of the strut, which surface faces the inside of the stent, has such a curvature that the strut cross section is fluidically optimized.

    摘要: The invention concerns an endovascular implant comprising a biodegradable material and having a tubular main body which is open at the ends and which is dilatable from an unexpanded condition into an expanded condition. The implant is so designed that when the implant in the expanded condition is subjected to a radially acting compression pressure in the range of between 5 and 30 kPa (0.05-0.3 bar) a cross-sectional area of the implant is reduced to 70% or less of the original cross-sectional area, or an internal volume of the implant is reduced to 70% or less of the original internal volume.
