Abstract:
A stent, an intermediate article in the manufacture of a stent, and a method of forming a stent from a workpiece are disclosed. A portion of the wall thickness of a workpiece may be removed, demarcating the structural framework of a stent from the remainder of the workpiece material during a cutting process. In some embodiments, a residuum layer of material remaining after a cutting process may have a recessed surface in relation to a first surface of the structural framework of the stent formed in the workpiece. In some embodiments, a plurality of kerf channels may be cut in a workpiece to demarcate a structural framework of a stent from waste material of the workpiece. In some embodiments, a series of perforations may, at least in part, demarcate the structural framework of a stent from the remainder of the workpiece material. The waste material and/or residuum material may be removed from the structural framework of a stent during a post-cutting process.
