Title
(EN) COVERED STENT
(FR) STENT RECOUVERT
(ZH) 覆膜支架
Abstract
(EN)
A covered stent, comprising an outer membrane (103), an inner membrane (100) and a bare stent (101) which is disposed between the outer membrane (103) and the inner membrane (100), at least one tying wire (102) being disposed on an outer surface of the outer membrane (103) or/and between the outer membrane (103) and the inner membrane (100). The tying wire (102) is wound in a ring or a spiral shape about an outer surface of the bare stent (101), an inner surface of the bare stent (101) or an outer surface of the inner membrane (100); or the tying wire (102) passes between an inner surface and an outer surface of two connection rods of the bare stent (101). By using an anti-extension function of the tying wire (102) and by means of a coating means of the tying wire (102), a covered stent is effectively prevented from expanding under the impact of high pressure blood flow, thereby reducing the risk of function loss of the covered stent due to the expansion of the covered stent.
(FR)
L'invention concerne un stent recouvert, comprenant une membrane externe (103), une membrane interne (100) et un stent nu (101) qui est disposé entre la membrane externe (103) et la membrane interne (100), au moins un fil d'attache(102) étant disposé sur la surface externe de la membrane externe (103) et/ou entre la membrane externe (103) et la membrane interne (100). Le fil d'attache (102) est enroulé en anneau ou en spirale autour de la surface externe du stent nu (101), de la surface interne du stent nu (101) ou de la surface externe de la membrane interne (100) ; ou le fil d'attache (102) passe entre la surface interne et la surface externe de deux tiges de connexion du stent nu (101). Grâce à une fonction anti-extension du fil d'attache (102) et à un moyen de revêtement du fil d'attache (102), on peut efficacement empêcher un stent recouvert de se dilater sous l'effet d'un flux sanguin à haute pression, ce qui permet de réduire le risque de perte de fonction du stent recouvert résultant de la dilatation de celui-ci.
(ZH)
一种覆膜支架,其包括外膜(103)、内膜(100)以及设置于外膜(103)与内膜(100)之间的裸支架(101),外膜(103)的外表面或/和外膜(103)与内膜(100)之间设置有至少一根绑线(102)。绑线(102)呈环状或螺旋状地缠绕于裸支架(101)的外表面、裸支架(101)的内表面或内膜(100)的外表面上;或绑线(102)穿梭于裸支架(101)的两根连接杆的内表面与外表面之间。利用绑线(102)的抗延伸性能,通过添加绑线(102)的覆膜方式,有效抑制覆膜支架在高压血流冲击下膨胀,从而减低由于覆膜支架膨胀而使覆膜支架功能失效的风险。
