Title (EN) MATERIALS HAVING SUPERELASTIC PROPERTIES INCLUDING RELATED METHODS OF FABRICATION AND DESIGN FOR MEDICAL DEVICES
(FR) MATÉRIAUX AYANT DES PROPRIÉTÉS SUPERÉLASTIQUES COMPRENANT DES PROCÉDÉS DE FABRICATION ET DE CONCEPTION ASSOCIÉS POUR DES DISPOSITIFS MÉDICAUX
Abstract:
(EN) There are super elastic NiTi materials for use as medical components, especially implantable medical components, and methods of fabricating such components to have desired R-phase characteristics in-vivo. Additionally, there are methods of processing a TiNi material to produce an implantable medical component by cold or warm working the TiNi material at least 15%; aging the cold or warm worked TiNi material under stress at between 300-700°C; and further aging the TiNi material below 300°C to produce desired R-phase characteristics. Additionally, there are methods of processing a TiNi material to produce a medical component by processing the TiNi material to produce a medical component that has a stress free M*s below a normal body temperature. Additionally, a TiNi material is used to produce a super elastic medical component from a tube, a sheet, a wire or a strip to have a stress free M*s below a normal body temperature.
(FR) La présente invention concerne des matériaux NiTi superélastiques pour utilisation en tant que composants médicaux, en particulier des composants médicaux implantables, et des procédés de fabrication de tels composants de façon à avoir des caractéristiques de phase R souhaitées in vivo. L’invention concerne en outre des procédés de traitement d’un matériau TiNi pour produire un composant médical implantable par travail à froid ou à chaud du matériau TiNi d’au moins 15 % ; vieillissement du matériau TiNi travaillé à froid ou à chaud sous contrainte entre 300 et 700 °C ; et vieillissement plus avant du matériau TiNi au-dessous de 300 °C pour produire des caractéristiques de phase R souhaitées. L’invention concerne en outre des procédés de traitement d’un matériau TiNi pour produire un composant médical par traitement du matériau TiNi pour produire un composant médical qui présente un M*s sans contrainte inférieur à une température corporelle normale. En outre, un matériau TiNi est utilisé pour produire un composant médical superélastique à partir d’un tube, d’une feuille, d’un fil ou d’une bande de façon à avoir un M*s sans contrainte inférieur à une température corporelle normale.
