Title (EN) COVERED STENT
(FR) STENT RECOUVERT
(ZH) 覆膜支架
Abstract:
(EN) A covered stent comprises a bare stent and coatings connected to the bare stent. The coatings comprise a first film and a second film in contact with the first film. The bare stent comprises multiple axially-distributed wavelike rings. Each wavelike ring comprises multiple peaks, multiple valleys, and multiple rod bodies connecting the peaks and the valleys that are adjacent. The second film covers at least one rod body and exposes the peaks and the valleys, and an angle between the extension direction of the second film at the position of the covered rod body and the axial direction of the covered stent is not greater than 75°.
(FR) La présente invention concerne un stent recouvert qui comprend un stent nu et des revêtements reliés au stent nu. Les revêtements comprennent un premier film et un deuxième film en contact avec le premier film. Le stent nu comprend des anneaux multiples de forme ondulée à distribution axiale. Chaque anneau de forme ondulée comprend des pics multiples, des vallées multiples et des corps de capsule multiples reliant les pics et les creux qui sont adjacents. Le deuxième film recouvre au moins un corps de tige et expose les pics et les vallées, et un angle entre la direction d’extension du deuxième film à la position du corps de tige recouvert et la direction axiale du stent recouvert n’est pas supérieur à 75°.
(ZH) 一种覆膜支架,包括裸支架及与所述裸支架连接的覆膜,所述覆膜包括第一膜片及与所述第一膜片贴合的第二膜片,所述裸支架包括多个沿轴向分布的波圈,所述波圈包括多个波峰、多个波谷及连接相邻所述波峰及所述波谷的多个杆体,所述第二膜片覆盖至少一所述杆体,并裸露出所述波峰及所述波谷,且所述第二膜片在被覆盖的所述杆体位置处的延伸方向与所述覆膜支架的轴向方向之间的夹角不大于75°。
