A medical guidewire system comprising a first inner member (20) having a firs outer diameter, a second intermediate member (30) having a second outer diameter larger than the first outer diameter, and a third outer member (40) having a third diameter larger than the second outer diameter of the second member. The second member (30) has a longitudinal extending opening to receiv the first member (20) for sliding movement with respect to the first member and the third outer member has a longitudinally extending opening to receive the second member (30) for sliding movement with respect to the first and second member. The first member has a first stiffness, the third member has a third stiffness greater than the first stiffness, and the second member is movable to stiffen the guidewire system.
L'invention concerne un système de fil de guidage médical qui comprend un premier élément interne (20) ayant un premier diamètre externe, un second élément intermédiaire (30) ayant un deuxième diamètre externe plus grand que le premier diamètre externe, et un troisième élément externe (40) ayant un troisième diamètre plus grand que le deuxième diamètre externe du deuxième élément. Le deuxième élément (30) possède une ouverture s'étendant longitudinalement destinée à recevoir le premier élément (20) en vue du mouvement coulissant par rapport au premier élément et le troisième élément externe possède une ouverture s'étendant longitudinalement destinée à recevoir le deuxième élément (30) en vue du mouvement coulissant par rapport aux premier et deuxième éléments. Le premier élément a une première rigidité, le troisième élément a une troisième rigidité et le deuxième élément est mobile pour rendre rigide le système de fil de guidage.
