Abstract

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。
