圆顶形过滤装置及其制造方法

一种用由至少一股线制成的织物片制造具有三维(3D)结构的栓塞过滤膜的方法，以及包括这种过滤膜的装置。过滤膜使用由两个部件制成的模具制造，第一部件具有由第一表面围绕的三维结构形状的腔，第二部件具有由第二个表面围绕的三维结构形状的突起。当模具闭合时，在空腔的表面和突出部分的表面之间存在空间。 A method of manufacturing an emboli filter membrane having a three-dimensional (3D) structure from a sheet of fabric made from at least of strand and a device comprising such filter membrane. The filter membrane is manufactured using a mold made from two parts, a first part having a cavity in the shape of the three-dimensional structure surrounded by a first surface, a second part having a protrusion in the shape of the three-dimensional structure surrounded by a second surface. When the mold is closed there is a space between a surface of the cavity and a surface of the protruding portion.
