Title (EN) NITINOL ALLOY COMPOSITION FOR VASCULAR STENTS
(FR) CONCEPTION ET COMPOSITION DE NITINOL POUR STENTS VASCULAIRES
Abstract:
(EN) A stent and a delivery system for implanting the stent in a body lumen is disclosed. The stent is made from a superelastic alloy such as nickel-titanium or nitinol, and includes a ternary element in order to minimize the stress hysteresis of the superelastic material. The stress hysteresis is defined by the difference between the loading plateau stress and the unloading plateau stress of the superelastic material. The resulting delivery system has a small profile and includes a sheath covering the stent that has a thin wall.
(FR) L'invention concerne un stent et un système de distribution permettant d'implanter le stent dans une lumière corporelle. Ce stent, qui est constitué d'un alliage superélastique tel que du nickel-titane ou du nitinol, comporte un élément ternaire permettant de minimiser l'hystérésis de contrainte du matériau superélastique. Cette hystérésis de contrainte est définie par la différence entre la contrainte du plateau de chargement et la contrainte du plateau de déchargement du matériau superélastique. Le système de distribution ainsi obtenu présente un profil réduit et comporte une gaine recouvrant le stent et comportant une paroi fine.
