A stent for a vessel inserted in use into the vessel of a living body including a tubular member constituting a passageway from one end to its opposite end. In one aspect, there is provided a computer-implemented method. The bended liquid crystal display has a better stability, and has no variation in its degree of curvature over service time. In addition, graphical user interface facets are described which map to pipeline parameters to control the processing steps and arrangements responsively and intuitively. In addition, the skirt may passively inhibit endoleak formation by sufficiently restricting blood flow to allow coagulation and clot formation, which would act as a barrier against endoleakage. The first light emitting diodes face the second reflective members, and the second light emitting diodes face the first reflective members.
