(ZH) 一种血管支架
Abstract
(EN) Disclosed is a vascular stent, said vascular stent being a self-expanding braided tube formed by cross-weaving of first and second components, or the blood vessel stent being a self-expanding braided tube formed by cross-braiding of the second component; the first component comprises at least one first braided wire (11), said first braided wire (11) comprising a first core wire (111) and a sleeve (112) covering the outside of said first core wire (111); and the second component comprises at least one first braided wire (11) and at least one second braided wire (12). The vascular stent provided by the present invention can be developed as a whole, the boundary of the vascular stent can be seen during surgery, the surgeon can determine clearly whether the vascular stent is attached to the wall, and the stent has a relatively high supporting force.
(FR) L'invention divulgue une endoprothèse vasculaire, ladite endoprothèse vasculaire étant un tube tressé auto-déployable formé par un tissage croisé de premier et second composants, ou l'endoprothèse de vaisseau sanguin étant un tube tressé auto-déployable formé par un tressage croisé du second composant; le premier composant comprenant au moins un premier fil tressé (11), ledit premier fil tressé (11) comprenant un premier fil d'âme (111) et un manchon (112) recouvrant l'extérieur dudit premier fil d'âme (111); et le second composant comprenant au moins un premier fil tressé (11) et au moins un second fil tressé (12). L'endoprothèse vasculaire selon la présente invention peut être développée en tant qu'ensemble, la délimitation de l'endoprothèse vasculaire peut être vue pendant une chirurgie, le chirurgien peut déterminer clairement si l'endoprothèse vasculaire est fixée à la paroi, et l'endoprothèse a une force de support relativement élevée.
(ZH) 一种血管支架,血管支架为由第一组分和第二组分交叉编织形成的自膨胀编织管,或者,血管支架为由第二组分交叉编织形成的自膨胀编织管,其中:第一组分包括至少一根第一编织丝(11),第一编织丝(11)包括第一芯丝(111)和包覆在第一芯丝(111)外面的套管(112);及第二组分包括至少一根第一编织丝(11)和至少一根第二编织丝(12)。血管支架可以整体显影,手术中能够看到血管支架的边界,医生可以清楚的判断血管支架是否贴壁,且具有较高支撑力。
