Stenting ring with marker

A stenting ring made of a tube or rolled-up sheet that has a wall with a characteristic wall thickness, the ring defining a lumen and being equipped with at least one marker made of a material different from a material of the ring, the ring being expansible from a radially compact disposition with a relatively small circumference to a radially expanded disposition with a relatively large circumference, the ring exhibiting in the compact disposition an arrangement of succeeding struts lying in alternate opposite directions, wherein the at least one marker:

• has a thickness in the radial direction of the ring that is less than the characteristic wall thickness, and has a width that extends circumferentially around an arc of the ring,
• includes radially extending portions, each radially extending portion tapering as it extends toward a :longitudinal axis of the stenting ring,
• is attached at a node connecting two struts, wherein the node and at least one of the two struts include surfaces mating with at least one of the radially extending portions,
• is attached to the ring at a zone located at a point intermediate in an extent of said arc, and
• at least partially radially overlaps with at least one strut adjacent to the arc when the ring is in the compact disposition, the at least one strut moving away from the at least one marker, when the ring expands toward said radially expanded disposition.
