摘要:
A tube stent includes a first tube body. The first tube body includes a first section, a second section, and a transition section located between the first section and the second section. One end of the transition section is connected to the first section, and the other end is connected to the second section. The shortening ratio of the first section (100) and the shortening ratio of the second section are smaller than the shortening ratio of the transition section. By using the tube stent, the pulsations of aortas are buffered by the transition section, so that vibration deformations of the tube stent are confined to the first section and the transition section, and accordingly the relative stability of the second section and branch blood vessels can be ensured, and the stimulations to walls of the branch blood vessels can be reduced.
