Title (EN) BIODEGRADABLE THROMBUS FILTER, AND MANUFACTURING METHOD, APPLICATION, AND DELIVERY DEVICE THEREOF

Abstract:
(EN) A biodegradable thrombus filter (100, 200, 11), a manufacturing method and application thereof, and a delivery device for delivering the thrombus filter (100, 200, 11), and a thrombus filter system comprising the thrombus filter (100, 200, 11) and the delivery device. The biodegradable thrombus filter (100, 200, 11) comprises a filter body (101, 201) and a center line (102, 202, 12). The filter body (101, 201) comprises a porous tubular frame (103, 203) and two porous filter mesh (104, 204) positioned at two ends of the porous tubular frame body (103, 203). The porous tubular frame (103, 203) and porous filter mesh (104, 204) are seamlessly formed via deposition of a biodegradable polymer fiber according to a pre-designed model. The center line (102, 202, 12) is manufactured using a biodegradable polymer. The center line (102, 202, 12) has one end connected to a top portion of the porous filter mesh (104, 204), passes through an internal portion of the filter (100, 200, 11) and the top portion of another porous filter mesh (104, 204), and extends outside the filter (100, 200, 11). The center line (102, 202, 12) is provided with two or more locking positions (105, 205). The center line (102, 202, 12) and the locking positions (105, 205) realize expansion of the filter (100, 200, 11) through a pulling action and allow adjustment to the size of filter expansion. The thrombus filter (100, 200, 11) has an adjustable expansion coefficient, so is less likely to be displaced, or to damage or perforate a vein during use.
(FR) L'invention concerne un filtre biodégradable pour thrombus (100, 200, 11), un procédé de fabrication et une application de celui-ci, et un dispositif de distribution pour administrer le filtre pour thrombus (100, 200, 11), et un système de filtre pour thrombus comprenant le filtre pour thrombus (100, 200, 11) et le dispositif de distribution. Le filtre biodégradable pour thrombus (100, 200, 11) comprend un corps de filtre (101, 201) et une ligne centrale (102, 202, 12). Le corps de filtre (101, 201) comprend un cadre tubulaire poreux (103, 203) et deux mailles de filtre poreuses (104, 204) positionnées au niveau de deux extrémités du corps de cadre tubulaire poreux (103, 203). Le cadre tubulaire poreux (103, 203) et les mailles de filtre poreuses (104, 204) sont formés sans soudure par dépôt d'une fibre polymère biodégradable selon un modèle pré-conçu. La ligne centrale (102, 202, 12) est fabriquée à l'aide d'un polymère biodégradable. La ligne centrale (102, 202, 12) a une extrémité reliée à une partie supérieure de la maille de filtre poreuse (104, 204), passe à travers une partie interne du filtre (100, 200, 11) et la partie supérieure d'une autre maille de filtre poreuse (104, 204), et s'étend à l'extérieur du filtre (100, 200, 11). La ligne centrale (102, 202, 12) est pourvue de deux positions de verrouillage (105, 205) ou plus. La ligne centrale (102, 202, 12) et les positions de verrouillage (105, 205) réalisent une expansion du filtre (100, 200, 11) par l'intermédiaire d'une action de traction et permettent un ajustement de la taille de l'expansion du filtre. Le filtre pour thrombus (100, 200, 11) a un coefficient d’expansion ajustable, de telle sorte qu'il est moins susceptible d'être déplacé, ou pour endommager ou perforer une veine pendant l'utilisation.
(ZH) 一种生物可降解血栓过滤器(100,200,11)及其制备方法、用途和用于输送血栓过滤器(100,200,11)的输送装置,和包含血栓过滤器(100,200,11)和输送装置的血栓过滤系统。生物可降解血栓过滤器(100,200,11)包括滤器主体(101,201)和中心线(102,202,12),滤器主体(101,201)包括多孔管状支架体(103,203)和位于多孔管状支架体(103,203)两端的两个多孔过滤网(104,204),多孔管状支架体(103,203)和多孔过滤网(104,204)是由生物可降解聚合物纤维按照预先设计的式样沉积而一体成型的,中心线(102,202,12)由生物可降解聚合物制成;其中,中心线(102,202,12)的一端与一个多孔过滤网(104,204)的顶端相连,并经由过滤器(100,200,11)内部延伸通过另一个多孔过滤网(104,204)的顶端至过滤器(100,200,11)的外部,中心线(102,202,12)上设置有两个以上卡位(105,205),通过中心线(102,202,12)及卡位(105,205)能够实现过滤器(100,200,11)的牵拉膨胀并且过滤器(100,200,11)的膨开尺寸可调。血栓过滤器(100,200,11)具有变化的可膨胀系数,在使用过程中不易发生移位、静脉损伤或穿孔。
