Abstract
(EN)
The objective of the present invention is to provide a filter device having a high fixing force with respect to a body lumen. A filter device (10) which is inserted into a body lumen to capture an object includes an elongate shaft portion (30), and an expanding portion (20) having a tubular shape in a natural state when not acted on by an external force, and comprising an elastically deformable tubular body which is coupled to the shaft portion (30), is braided using a plurality of wire-like bodies (21) comprising a Ni-Ti alloy, and is provided with gaps (21A), wherein, if the wire diameter of the wire-like bodies (21) is defined as d, and the sum of d3 for all the linear bodies (21) is defined as S1, S1 is 0.08 to 0.25 mm3.

L'objectif de la présente invention est de fournir un dispositif de filtration ayant une force de fixation élevée par rapport à une lumière corporelle. Un dispositif de filtration (10) qui est inséré dans une lumière corporelle pour capturer un objet comprend une partie d'arbre allongé (30), et une partie d'expansion (20) ayant une forme tubulaire dans un état naturel lorsqu'elle n'est pas sollicitée par une force externe, et comprenant un corps tubulaire élastiquement déformable qui est couplé à la partie d'arbre (30), est tressé à l'aide d'une pluralité de corps de type fils (21) comprenant un alliage Ni-Ti, et est pourvu d'espaces (21A), où, si le diamètre de fil des corps de type fil (21) est défini comme d, et la somme de d3 pour tous les corps linéaires (21) est définie comme S1, S1 est de 0,08 à 0,25 mm3.
