Title (EN) TUBE STENT
(FR) STENT TUBULAIRE
(ZH) 管腔支架
Abstract:
(EN) A tube stent (10) comprises a first tube body (101). The first tube body (101) comprises a first section (100), a second section (200), and a transition section (300) located between the first section (100) and the second section (200). One end of the transition section (300) is connected to the first section (100), and the other end is connected to the second section (200). The shortening rate of the first section (100) and the shortening rate of the second section (200) are smaller than the shortening rate of the transition section (300). By using the tube stent, the pulsations of aortas are buffered by the transition section (300), so that vibration deformations of the tube stent (10) are confined to the first section (100) and the transition section (300), and accordingly the relative stability of the second section (200) and branch blood vessels can be ensured, and the stimulations to walls of the branch blood vessels can be reduced.
(FR) La présente invention concerne un stent tubulaire (10) qui comprend un premier corps de tube (101). Le premier corps de tube (101) comprend une première section (100), une deuxième section (200) et une section de transition (300) située entre la première section (100) et la deuxième section (200). Une extrémité de la section de transition (300) est raccordée à la première section (100), et l’autre extrémité est raccordée à la deuxième section (200). Le taux de raccourcissement de la première section (100) et le taux de raccourcissement de la deuxième section (200) sont inférieurs au taux de raccourcissement de la section de transition (300). Au moyen du stent tubulaire, les pulsations d’aortes sont amorties par la section de transition (300), de telle sorte que les déformations dues aux vibrations du stent tubulaire (10) sont confinées à la première section (100) et à la section de transition (300) et, en conséquence, la stabilité relative de la deuxième section (200) et des vaisseaux sanguins ramifiés peut être assurée, et les stimulations des parois des vaisseaux sanguins ramifiés peuvent être réduites.
(ZH) 一种管腔支架(10),包括第一管体(101),该第一管体(101)包括第一分段(100)、第二分段(200)及位于第一分段(100)及第二分段(200)之间的过渡段(300),过渡段(300)的一端与第一分段(100)连接,另一端与第二分段(200)连接,第一分段(100)及第二分段(200)的短缩率小于过渡段(300)的短缩率。利用该管腔支架,主动脉的搏动可以被过渡段(300)缓冲,使管腔支架(10)的震动变形停留在第一分段(100)及过渡段(300),从而可以保证第二分段(200)与分支血管的相对稳定,减少对分支血管壁的刺激。
