Title
(EN) Intravascular stent
(ZH) 一种血管支架
Abstract
(EN) The invention discloses an intravascular stent, the intravascular stent is a self-expansion braided tube formed by cross-braiding of a first component and a second component, or the intravascular stent is a self-expansion braided tube formed by cross-braiding of the second component, the first component comprises at least one first braided wire, the first braided wire comprises a first core wire and a sleeve wrapping the first core wire; and the second component comprises at least one first braided wire and at least one second braided wire. The intravascular stent provided by the invention can be developed integrally, the boundary of the intravascular stent can be seen in an operation, a doctor can clearly judge whether the intravascular stent adheres to the wall or not, and the intravascular stent has high supporting force.
(ZH) 本发明公开了一种血管支架,所述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,所述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:所述第一组分包括至少一根第一编织丝,所述第一编织丝包括第一芯丝和包覆在所述第一芯丝外面的套管;及所述第二组分包括至少一根所述第一编织丝和至少一根第二编织丝。本发明提供的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。
