Abstract:
(EN) A filter (10), comprising a heart-proximal end (1), a heart-distal end (2) and a main filter body connected between the heart-proximal end (1) and the heart-distal end (2). The main filter body comprises a first filter unit (3) and a second filter unit (4), both being conical mesh structures, as well as multiple intermediate connection posts (5) connecting the first filter unit and the second filter unit. The intermediate connection posts (5) have provided thereon support posts (6). A support post (6) comprises a transition segment (61) extending from an intermediate connection post (5) to a blood vessel wall, and a support segment bent and extending from the transition segment (61), and at least partially abutting the blood vessel wall. The support segment comprises a main body (62) bent and extending from the end of the transition segment (61) and a flexible segment (63) bent and extending from the main body (62). A diameter of at least a portion of the flexible section (63) along a length thereof is smaller than a diameter of the main body (62), thereby increasing flexibility of the support section and preventing the support section from puncturing the blood vessel wall.
(FR) Ce filtre (10) comprend une extrémité proximale (1), une extrémité distale (2) ainsi qu’un corps principal de filtre venant entre l'extrémité proximale (1) et l’extrémité distale (2) en connexion. Le corps principal de filtre comprend une première unité de filtration (3), une seconde unité de filtration (4) et une tige de connexion intermédiaire (5) reliant une pluralité de premières unités de filtration et de secondes unités de filtration en connexion, le tout formant treillis de configuration conique. La tige de connexion intermédiaire (5) reçoit une une tige de support (6), laquelle (6) comprend un segment de transition (61) s'étendant en direction d’une paroi tubulaire de la tige de connexion intermédiaire (5) et un segment de support dont au moins une partie supporte la paroi des vaisseaux sanguins, ledit segment s’étendant plié depuis le segment de transition (61). Le segment de support comprend un corps (62) qui s’étend en accordéon depuis l'extrémité du segment de transition (61) ainsi qu’un segment souple (63) qui s’étend depuis le corps (62), le segment souple (63) ayant au moins sur la longueur une taille radiale partielle inférieure à la taille radiale du corps (62), assurant ainsi davantage de souples au segment de support, ce qui permet d’éviter que le segment de support ne pince la paroi des vaisseaux sanguins.
(ZH) 一种滤器(10),其包括近心端(1)、远心端(2)以及连接于近心端(1)和远心端(2)之间的滤器主体。滤器主体包括均为锥形网状结构的第一过滤单元(3)、第二过滤单元(4)以及多个连接第一过滤单元和第二过滤单元的中间连接杆(5)。中间连接杆(5)上设有支撑杆(6)。支撑杆(6)包括自中间连接杆(5)向血管壁延伸的过渡段(61)以及自过渡段(61)弯折延伸并至少有部分与血管壁抵接的支撑段。支撑段包括自过渡段(61)末端弯折延伸的本体(62)以及自本体(62)弯延伸的柔性段(63)。柔性段(63)在其长度方向上至少有一部分的径向尺寸小于本体(62)的径向尺寸从而增大支撑段的柔性,防止所述支撑段刺破血管壁。
