Alternative designs, materials and manufacturing methods for guidewires. Some embodiments pertain to a composite guidewire having proximal (14) and distal (16) section, and a connector (18) adapted and configured for permanently joining the proximal section (14) to the distal section (16). In some embodiments, at least one of the sections (16) is made of a linear-elastic nickel-titanium alloy. Several alternative guidewire tip designs including coiled safety/shaping structures are also disclosed.
La présente invention concerne des variantes de conceptions, de matériaux et de procédés de réalisation de fils-guides. Certains modes de réalisation correspondent à un fil-guide composite comprenant une partie distale et une partie proximale, un connecteur dont la conception et la configuration permettent une jonction permanente de la partie proximale à la partie distale. Dans certains modes de réalisation, au moins l'une des parties est constituée d'un alliage élastique linéaire nickel-titane. L'invention a également pour objet plusieurs variantes de conceptions de pointe de fil-guide comprenant des structures hélicoïdales de sécurité/mise en forme.
