Title
(EN) STENT FOR BLOOD VESSEL
(FR) ENDOPROTHÈSE POUR VAISSEAU SANGUIN
Abstract
(EN)
Disclosed is a stent for blood vessels, structured in a manner such that struts overlap with each other in a contracted state, thereby being capable of easily being inserted into a narrow blood vessel because it has a small diameter in a contracted state while having a strong radial force. This stent can be applied to a balloon-expandable type stent and to a self-expandable type stent. Accordingly, if the present invention is applied to the self-expandable type stent, a problem that the stent of this type can hardly be used to treat a narrow blood vessel can be overcome.
(FR)
La présente invention concerne une endoprothèse pour vaisseaux sanguins, structurée de manière à ce que des tuteurs se superposent l’un à l’autre dans un état contracté, ce qui permet à l’endoprothèse d’être facilement insérée dans un vaisseau sanguin étroit en raison de son petit diamètre à l’état contracté tout en ayant une force radiale puissante. Cette endoprothèse peut être appliquée à une endoprothèse de type ballon extensible et à une endoprothèse de type auto-extensible. Selon le cas, si la présente invention est appliquée à l’endoprothèse de type auto-extensible, le problème qui surgit quand une endoprothèse de ce type peut difficilement être utilisée pour traiter un vaisseau sanguin étroit, devient surmontable.
