Abstract
(EN) In order to provide a stent or the like that is capable of reducing the risk of damaging an interior wall of a tubular organ inside a body, this stent 11 is provided with a net-like structural body 111 that is formed using one or more wires W1 and that has a tubular structure that extends along the axial direction Z of the stent 11. The net-like structural body 111 has wire fixing parts Fw each for fixing together an end part of a wire W1 (W1a) to the same wire W1 or to another wire W1 (W1b). The wire crimping parts Fw are each configured using a fiber wire Wf which is wound around an end part of the wire W1 and the same or the other wire W1.
(FR) Selon l'invention, afin de fournir une endoprothèse ou similaire qui est apte à réduire le risque de lésion d'une paroi interne d'un organe tubulaire à l'intérieur d'un corps, cette endoprothèse (11) est pourvue d'un corps structurel de type filet (111) qui est formé à l'aide d'un ou de plusieurs fils (W1) et qui a une structure tubulaire qui s'étend le long de la direction axiale Z de l'endoprothèse (11). Le corps structurel de type filet (111) a des parties de fixation de fil (Fw) chacune destinée à fixer ensemble une partie d'extrémité d'un fil W1 (W1a) au même fil W1 ou à un autre fil W1 (W1b). Les parties de sertissage de fil (Fw) sont chacune conçues à l'aide d'un fil de fibre (Wf) qui est enroulé autour d'une partie d'extrémité du fil (W1) et du même fil ou de l'autre fil (W1).
(JA) 体内の管状器官の内壁を傷付けるリスクを低減することが可能なステント等を提供する。ステント11は、1または複数の線材W1を用いて形成され、このステント11の軸方向Zに沿って延在する筒状構造を有する網目状構造体111を備えている。この網目状構造体111は、線材W1(W1a)における端部と、その線材W1と同一または他の線材W1(W1b)とを、互いに固着する線材固着部Fwを有している。この線材固着部Fwは、線材W1における端部と上記同一または他の線材W1とを互いに巻回した、繊維線材Wfを用いて構成されている。
