Disclosed are an occluder (100), a manufacturing method thereof and a woven mesh pipe (520) for manufacturing the occluder (100), wherein the occluder (100) comprises an elastic woven body (110) made of a plurality of weaving filaments (113, 11, 12, 13, 14, 15, 16, 17) and in the extension direction of any weaving filament (11) in the woven body (110), weaving filaments (12, 13, 14, 15, 16, 17) which intersect with the weaving filament (11) comprise a plurality of first weaving sets and a plurality of second weaving sets, the first weaving sets and the second weaving sets being alternately located on two opposite sides of the weaving filament (11), and each first weaving set and each second weaving set respectively comprising at least two weaving filaments (12, 13, 14, 15, 16, 17) extending in the same direction. By means of the weaving structure, the bonding force between the weaving filaments is relatively small, so that sheathing force is reduced, sheathing of the occluder is facilitated, and thus the occluder can adapt to a relatively small sheath pipe. Meanwhile, by means of rationally arranging the number of weaving filaments in the first and the second weaving sets, it can be ensured that the weaving filaments are compactly woven, such that the occluder can have enough elasticity and radial supporting force after being unsheathed, thereby effectively plugging a missing part.Linvention concerne un dispositif docclusion (100), son procédé de fabrication, et un tuyau à maille tissée (520) pour fabriquer le dispositif docclusion (100), le dispositif docclusion (100) comprenant un corps tissé élastique (110) constitué dune pluralité de filaments de tissage (113, 11, 12, 13, 14, 15, 16, 17) et, dans la direction dextension dun filament de tissage quelconque (11) dans le corps tissé (110), des filaments de tissage (12, 13, 14, 15, 16, 17) qui se coupent avec le filament de tissage (11) comprennent une pluralité de premiers ensembles de tissage et une pluralité de s
