Title (EN) GUIDEWIRES WITH IMPROVED FATIGUE LIFE AND METHODS OF MAKING THE SAME
(FR) FILS DE GUIDAGE AYANT UNE DURÉE DE VIE AMÉLIORÉE À LA FATIGUE ET LEURS PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)A medical device, such as a medical guidewire, having a portion including an inner zone of material and an outer peripheral zone of material surrounding the inner zone of material. The inner zone of material has a first coefficient of thermal expansion and the outer peripheral zone of material has a second coefficient of thermal expansion less than the first coefficient of thermal expansion, wherein at an operating temperature the outer peripheral zone of material opposes expansion of the inner zone of material such that the outer peripheral zone of material exerts a compressive stress on the inner zone of material.
(FR)L'invention concerne un dispositif médical, tel qu'un fil de guidage médical, présentant une partie comprenant une zone intérieure de matériau et une zone périphérique extérieure de matériau entourant la zone intérieure de matériau. La zone intérieure de matériau a un premier coefficient de dilatation thermique et la zone périphérique extérieure de matériau a un second coefficient de dilatation thermique plus petit que le premier coefficient de dilatation thermique, la zone périphérique extérieure de matériau s'opposant, à une température de fonctionnement, à la dilatation de la zone intérieure de matériau de sorte que la zone périphérique extérieure de matériau exerce une contrainte de compression sur la zone intérieure de matériau.
