Stenting Ring with Marker
First Claim
1. A stenting ring made of a tube or roiled-up sheet that has a characteristic wall thickness, the ring defining a lumen and being equipped with at least one marker made of a material different from that 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 a serpentine arrangement of succeeding struts lying in alternate opposite directions to the longitudinal axis of the lumen, whereinthe 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, whereinthe marker is attached to the ring at a zone located at a point intermediate in the extent of said arc, and whereinthe marker overlaps with a respective one of said struts, at each end of its circumferential arc, when the ring is in the compact disposition, the respective struts moving away from each other, and from the marker, when the ring expands towards said radially expanded disposition.

Abstract
A stenting ring made of a tube or rolled-up sheet that has a characteristic wall thickness. The ring defines a lumen and is equipped with at least one marker made of a material different from that of the ring. The ring is expansible from a radially compact disposition with a relatively small circumference to a radially expanded disposition with a relatively large circumference. The ring exhibits in the compact disposition a serpentine arrangement of succeeding struts lying in alternate opposite directions to the longitudinal axis of the lumen. The 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. The marker is attached to the ring at a zone located at a point intermediate in the extent of said arc. The marker overlaps with a respective one of said struts, at each end of its circumferential arc, when the ring is in the compact disposition, the respective struts moving away from each other, and from the marker, when the ring expands towards said radially expanded disposition.

15. A stent, comprising:
-
a plurality of stenting rings including an end stenting ring, the end stenting ring including a plurality of nodes, each node formed by two struts joined together at an end thereof, the struts forming the nodes lying adjacent one another generally parallel with a longitudinal axis of the stent in a stent radially compact configuration; and a marker attached to a marker node, the marker having a thickness in a radial direction of the end stenting ring that is less than a wall thickness thereof, the marker overlapping each of the nodes adjacent to the marker node in the stent radially compact configuration. - View Dependent Claims (16, 17, 18, 19, 20)
