摘要： 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.

摘要： A radially expansible annular stent is disclosed. The stent comprises a plurality of stenting turns around a lumen centred on a longitudinal axis. Adjacent turns of the stent are joined by connector struts. The stent annulus has a wall thickness related to the material from which it is formed. The radial thickness of the connector struts is smaller than that of the stent annulus. A method of making such a stent is also disclosed. The method includes cutting the connector struts from a tubular workpiece with a laser beam. The laser beam is aimed so as to be offset from a longitudinal axis of the workpiece to provide the reduced radial thickness of the connector struts.

摘要： Normally, when stents are bent, inside the body of the stented patient, there is head-to-head collision between facing V-points on the inside of the bend. However, by alternating between two whole numbers the number of struts between successive connectors around the circumference of each of the stenting rings, the V-points are caused to veer circumferentially in opposite directions as they approach each other on the inside of the bend, so allowing them to pass by each other without collision, thereby allowing in the same stent both close packing of the ring stack, and an enhanced ability to tolerate severe bending, after placement in the body.

摘要： A method of cutting, polishing and then welding together two metallic components (10, 18), in which the respective components (10, 18) are cut to define respective cut surfaces (14, 16) that are to be polished and fitted together, both to define the relative positions of the two components (10, 18) to be fixed by the welding and to provide facing weld surfaces at which the two components (10, 18) can be welded together. The method is characterized by the steps of i) making at least one extra cut (20), to create at least one zone of elastic deformation that deforms when the cut surfaces (14, 16) are fitted together; ii) polishing the cut surfaces (14, 16) before fitting them together; and iii) designing the dimensions of the cut components (10, 18) so that the zones of elastic deformation compensate for the variations of dimensions caused by the polishing step, thereby retaining the capability of the polished cut surfaces (14, 16, 20) to define said component (10, 18) relative positions during the welding step.
