Title
(EN) CATHETER
(FR) CATHÉTER
(JA) カテーテル
Abstract
(EN) Provided is a catheter in which twisting of a curved shaft at the distal part of the catheter is prevented, decreases in the bending and pushability of the catheter are prevented, and the expected curve shape can be achieved. A catheter (1) comprises: a shaft (2); at least one wire (30); a coil (60); a leaf spring (40) that has a first connection part (41) of which a proximal end part is fixed to a distal end part of the coil (60); and a cover tube (50). The coil (60) has a fixed part (61) that is fixed to the shaft (2) to the proximal side of the proximal end of the cover tube (50), and in the longitudinal direction, the length of the fixed part (61) from the distal end to the proximal end of the cover tube (50) is at most 20 turns of the coil (60).
(FR) L'invention concerne un cathéter dans lequel la torsion d'un corps incurvé à la partie distale du cathéter est évitée, les diminutions de la flexion et de la capacité de poussée du cathéter sont prévenues, et la forme incurvée attendue peut être obtenue. L'invention concerne également un cathéter (1) comprenant : un corps (2) ; au moins un fil (30) ; une bobine (60) ; un ressort à lame (40) qui comporte une première partie de liaison (41) dont une partie d'extrémité proximale est fixée à une partie d'extrémité distale de la bobine (60) ; et un tube de recouvrement (50). La bobine (60) comporte une partie fixe (61) qui est fixée au corps (2) du côté proximal de l'extrémité proximale du tube de recouvrement (50), et dans la direction longitudinale, la longueur de la partie fixe (61) de l'extrémité distale à l'extrémité proximale du tube de recouvrement (50) est au maximum de 20 tours de la bobine (60).
(JA) カテーテル遠位部の湾曲軸のねじれを防止しつつ、カテーテルの折れ曲りやプッシャビリティの低下を防止し、所期の湾曲形状を実現できるカテーテルを提供する。 カテーテル(1)は、シャフト(2)と;1つ以上のワイヤー(30)と;コイル(60)と;近位端部がコイル(60)の遠位端部に固定されている第1接続部(41)を有する板バネ(40)と;カバーチューブ(50)とを有しており、コイル(60)はカバーチューブ(50)の近位端よりも近位側でシャフト(2)と固定されている固定部(61)を有しており、長手方向において、固定部(61)の遠位端からカバーチューブ(50)の近位端までの長さは、コイル(60)の20巻き分以下である。
