Title (EN) VARIABLE EXPANSION FORCE STENT
(FR) EXTENSEUR A FORCE D'EXPANSION VARIABLE
Abstract:
(EN) A stent having varying outward radial force along its length. In use, the stent can provide greater force in vessel regions requiring greater force and less force in regions requiring less. In particular, more force is provided in the narrowed, center of a stenosis, while not applying too much force to the adjoining healthy tissue area. Greater stent expansion is provided in wider vessel geometries and less stent expansion in narrower regions. Varying force is achieved varying the number of elements, the density of elements, and the thickness of the elements.
(FR) La présente invention concerne un extenseur à force radiale extérieure variable sur sa longueur. Lors de l'utilisation, l'extenseur peut exercer une force plus grande sur des régions vasculaires nécessitant une force accrue, et une force moins grande sur des régions requérant d'une force plus limitée. On exerce, en particulier, une force plus grande sur le centre rétréci d'une sténose tout en exerçant une force moindre sur la zone de tissu sain adjacente. L'expansion de l'extenseur est plus importante dans des vaisseaux de plus grande largeur et moins marquée dans les régions plus étroites. On obtient une force variable en faisant varier le nombre, la densité et l'épaisseur des éléments.
