Abstract

La présente invention concerne un procédé de fabrication d'un élément métallique central destiné à un fil-guide médical consistant à utiliser un fil d'alliage nickel-titane dont une longueur comprend une partie proximale ayant un premier diamètre et une partie distale ayant un deuxième diamètre ; à appliquer un écrouissage à la partie distale sans appliquer d'écrouissage à la partie proximale, conférant ainsi à la partie distale un troisième diamètre qui est inférieur au deuxième diamètre ; et ensuite à appliquer un processus de réduction au fil permettant de réduire le diamètre de la partie proximale jusqu'à atteindre un quatrième diamètre qui est inférieur au premier diamètre.
