摘要：
Vascular filter comprising a first zone and a second zone (17), the mobile filter being between a collapsed position for its contribution to the vessel and a range of expanded positions for placement within the vessel, the first zone having a filtration part ( 19) which has a converging zone (21) to direct the particles towards the center of the filter, the first zone including a plurality of elongated spaced struts (14, 114, 214) and a plurality of connecting struts (14a, 14b, 114a , 114b) running at an angle from the elongated struts, the second zone (17) being widened in the expanded positions in order to present a transverse dimension that increases towards a second end part opposite to the filtration part, including the second zone a part (72a, 72b, 172a, 172b, 272a, 272b) of hooking to the vessel in the second end portion having a plurality of hooks hooking to the vessel, the area containing the hooks having a at the first transverse dimension, the first zone having a spacer (40a, 40b, 70 ', 70 ", 154, 264, 364, 420, 422, 520, 522, 620, 622) that runs radially with respect to a longitudinal axis of the filter, the spacer having a second transverse dimension, where in a non-constricted expanded position the second transverse dimension of the spacer is smaller than the first transverse dimension of the area of the hooks to the vessel to thus provide a lower profile in the spacer zone, characterized in that the spacer (40a, 40b, 70 ', 70 ", 154, 264, 364, 420, 422, 520, 522, 620, 622) is made of a helical cutout (45a, 45b, 152, 262, 320, 322, 326, 328, 365, 426, 426a, 426b, 526a, 526b, 626a, 626b) made in the first zone of the filter.Filtro vascular que comprende una primera zona y una segunda zona (17), siendo el filtro móvil entre una posición colapsada para su aporte al vaso y una gama de posiciones expandidas para su colocación dentro del vaso, teniendo la primera zona una parte de filtración (19) que tiene una zona convergente (21) para dirigir las partícula
