バルーンカテーテル
Abstract:
(EN)
[Problem] To provide a balloon catheter with which an increase in size of the outer shape of a balloon when folded can be prevented, and with which the balloon can be prevented from falling off an outer tube shaft. [Solution] A balloon 150 of a balloon catheter 10 in which, in a state in which the balloon is contracted and an extension portion 153 of the balloon is circumferentially wrapped around an inner tube shaft 110, a proximal end-side transition portion 154 of the balloon is not wrapped around an inner tube shaft. An outer tube shaft 120 extends distally of a proximal end-side fixed portion 152 of the balloon, and is fixed to the inner tube shaft in a position corresponding to the proximal end-side transition portion of the inner tube shaft.
(FR)
Le problème décrit par la présente invention est de produire un cathéter à ballonnet permettant d'empêcher une augmentation de la taille de la forme extérieure d’un ballonnet lorsqu’il est plié, et permettant d'empêcher que le ballonnet se détache d’une tige de tube externe. La solution selon l’invention porte sur un ballonnet (150) d’un cathéter à ballonnet (10) dans lequel, dans un état dans lequel le ballonnet est contracté et une partie d’extension (153) du ballonnet est enveloppée de manière circonférentielle autour d’une tige de tube interne (110), une partie de transition côté extrémité proximale (154) du ballonnet n’est pas enveloppée autour d’une tige de tube interne. Une tige de tube externe (120) s’étend de manière distale d’une partie fixe côté extrémité proximale (152) du ballonnet, et est fixée à la tige de tube interne dans une position correspondant à la partie de transition côté extrémité proximale de la tige de tube interne.

【課題】バルーンを折り畳んだ際にバルーンの外形形状が大きくなるのを防止でき、かつ、バルーンが外管シャフトから脱落するのを防止できるバルーンカテーテルを提供する。 【解決手段】バルーンカテーテル10のバルーン150は、バルーンが収縮し、バルーンの拡張部153が内管シャフト110の周方向に巻き付けられた状態で、バルーンの基端側遷移部154が内管シャフトに巻き付けられておらず、外管シャフト120は、バルーンの基端側固定部152よりも先端側に延在しており、かつ、内管シャフトの基端側遷移部に対応する位置で内管シャフトに固定されている。
