Abstract

A stent, in particular a coronary stent, includes a thin-walled, hollow-cylindrical base body of an X-ray transparent material, the surface area of which has an open-worded, net-shaped design owing to recesses. The stent has at least one X-ray opaque element or region, wherein the X-ray opaque element or the X-ray opaque region extends essentially in a linear direction over at least a portion of the circumference of the stent located at least one end region of the stent while the rest of the stent remains X-ray transparent.
