The stent (4) is made of a suitable material and provided with a v-shaped lateral groove (5, 7) created by guiding a cool fluid through the stent (4) reflecting a laser beam from inside. A string made of tantalum or another material visible under the use of x-rays with a round, rectangular or polygonal cross section is inserted into the groove serving as a self-centering marker (3). The remaining space is filled with a polymer (1) fixing the marker (3) inside the groove (5). |
