摘要:
A lumen woven support (100), comprising a netted tube body (10) woven by weaving filaments (1), wherein the netted tube body (10) comprises a first portion (110) and a second portion (120) along an axial direction the netted tube body (10) further comprises a plurality of first hooked and wound knots (140), at least two weaving filaments (1) from one end of the second portion (120) are hooked and wound to each other in the axial direction of the netted tube body (10) to form a first hooked and wound knot (140) and are then separated, and all the weaving filaments (1) constituting the first hooked and wound knots (140) are woven to form the first portion (110) and the mesh density of the first portion (110) is smaller than that of the second portion (120). In the above-mentioned lumen woven support (100), since the mesh density of the first portion (110) is smaller than that of the second portion (120), the radial supporting force of the first portion (110) is reduced, and the stimulation to a normal lumen wall caused by the first portion (110) is reduced, thereby lowering a risk of restenosis. In addition, the first portion (110) has a good flexibility, the second portion (120) has a greater radial supporting force so as to provide sufficient anchoring, and therefore, the above-mentioned lumen woven support (100) is applicable to practical implantation.La présente invention concerne un support tissé (100) de lumière, comprenant un corps tubulaire (10) en treillis tissé par des filaments de tissage (1), ledit corps tubulaire (10) en treillis comprenant une première partie (110) et une seconde partie (120) le long dune direction axiale ledit corps tubulaire (10) en treillis comprend en outre une pluralité de premiers nœuds (140) accrochés et enroulés, au moins deux filaments de tissage (1) depuis une extrémité de la seconde partie (120) étant accrochés lun à lautre et enroulés dans la direction axiale du corps tubulaire (10) en treillis pour former un premier nœud (1
