Title (EN) FILTER FOR IMPLANTING INTO BLOOD VESSEL
(FR) FILTRE DESTINÉ À ÊTRE IMPLANTÉ DANS UN VAISSEAU SANGUIN
(ZH) 一种用于植入血管内的滤器
Abstract:
(EN) A filter (1000) for implanting into a blood vessel, comprising a central connecting part (1300) and a filter part (1100) and a support part (1200) connected to the central connecting part (1300), the support part (1200) being a plurality of support rods (1210) distributed in a radiating manner, at least some of the support rods (1210) being rolling sections (1212) that bend away from the filter part in a released state, the curvature of the rolling sections (1212) gradually increasing from the side nearest to the central connecting part (1300). By means of changing the shape of the support part (1200), when released, the end of the present filter for implanting into a blood vessel can be immediately rolled up to prevent puncturing of the tissue.
(FR) L'invention concerne un filtre (1000) destiné à être implanté dans un vaisseau sanguin, comprenant une partie de raccordement centrale (1300) ainsi qu'une partie filtre (1100) et une partie support (1200) reliées à la partie de raccordement centrale (1300), la partie support (1200) étant constituée d'une pluralité de tiges de support (1210) réparties de manière rayonnante, au moins certaines des tiges de support (1210) étant des sections de roulement (1212) qui s'éloignent, en se courbant, de la partie filtre dans un état libéré, la courbure des sections de roulement (1212) augmentant progressivement depuis le côté le plus proche de la partie de raccordement centrale (1300). Grâce à la modification de la forme de la partie support (1200), lorsqu'elle est libérée, l'extrémité dudit filtre à implanter dans un vaisseau sanguin peut être immédiatement enroulée pour empêcher la perforation du tissu.
(ZH) 一种用于植入血管内的滤器(1000),包括中心连接部(1300)以及与中心连接部(1300)相连的过滤部(1100)和支撑部(1200),其中支撑部(1200)为辐射分布的多根支杆(1210),支杆(1210)的至少一部分为释放状态下背向过滤部弯曲的翻卷段(1212),翻卷段(1212)由邻近中心连接部(1300)一侧起曲率逐渐增大。此植入血管内的滤器(1000),通过对支撑部(1200)形状的改进,在释放时其末端可及时翻卷避免刺伤组织。
