Abstract
(EN)
The present invention relates to a covered stent and a preparation method therefor. The covered stent comprises a stent body and a covering membrane. The stent body has a first surface and a second surface opposite the first surface. The covering membrane comprises a first membrane and a second membrane. The first membrane is arranged on the first surface. The second membrane is arranged on the second surface and is bonded with the first membrane. The covering membrane further comprises a connector fixedly connected to the stent body. The connector is located between the first membrane and the second membrane. The connector is bonded with at least one of the first membrane and the second membrane. The covered stent can improve the connection strength between the covering membrane and the stent body.

La présente invention concerne un stent couvert et son procédé de préparation. Le stent couvert comprend un corps de stent et une membrane de couverture. Un corps de stent possède une première surface et une deuxième surface opposée à la première surface. La membrane de couverture comprend une première membrane et une seconde membrane. La première membrane est disposée sur la première surface. La seconde membrane est disposée sur la seconde surface et est liée à la première membrane. La membrane de couverture comprend en outre un connecteur connecté de manière fixe au corps de stent. Un connecteur est situé entre la première membrane et la seconde membrane. Le connecteur est lié à au moins l'une de la première membrane et de la seconde membrane. Le stent couvert peut améliorer la force de liaison entre la membrane de couverture et le corps de stent.
