Abstract:
(EN) A catheter 1 is provided with a shaft 5 through which a first wire 7 and a second wire 9 which has a bend at the front end 9a thereof are passed. The shaft 5 has: a first lumen 20 which is formed by a first wall surface 24a and through which the first wire 7 is passed; and a second lumen 22 which is formed by a second wall surface 26a, is provided next to the first lumen 20 with a partition wall therebetween, and has the second wire 9 passed therethrough. The first lumen 20 and the second lumen 22 are arranged in the longitudinal direction of the shaft 5. In a cross-section of the shaft 5, taken perpendicular to the longitudinal direction thereof, a first point P6 on the second wall surface 26a, at which the distance between the outer surface 28a of the shaft 5 and the second wall surface 26a is smallest is located at a position not overlapping with a first straight line D1, D2 which connects predetermined two points P1 and P2 or two points P3 and P4 on the second wall surface 26a and which is longest.
(FR) Un cathéter est pourvu d'une tige à travers laquelle un premier et un second fil, ayant un coude à l'extrémité avant, sont passés. La tige a une première lumière (20), formée par la paroi (24a), à travers laquelle passe le premier fil (7), et une seconde lumière (22), formée par une seconde paroi (26a), près de la première lumière (20), avec une paroi de séparation entre les deux. Le second fil (9) passe à travers celle-ci. La première et la seconde lumière sont dans le sens longitudinal de la tige. Une section transversale de la tige (5), perpendiculaire à la longitudinale, a un premier point (P6) sur la deuxième paroi (26a). La distance entre la surface externe de la tige et la seconde paroi est plus petite à l'endroit où la première ligne droite (D1, D2) qui relie deux points (P1 et P2) prédéterminés, ou deux points (P3 et P4) sur la deuxième de paroi (26a) et qui est la plus longue.
(JA) カテーテル1は、第1ワイヤー7、及び、先端9aに屈曲部を有する第2ワイヤー9のそれぞれを通過させるシャフト5を備え、シャフト5は、第1壁面24aにより形成され、第1ワイヤー7を通過させる第1ルーメン20と、第2壁面26aにより形成されると共に第1ルーメン20と隔壁を挟んで並んで設けられ、第2ワイヤー9を通過させる第2ルーメン22と、を有し、第1ルーメン20及び第2ルーメン22は、シャフト5の長手方向に沿って配置され、シャフト5の長手方向に直交する断面において、シャフト5の外面28aと第2壁面26aとの間隔が最薄となる第2壁面26a上の第1点P6は、第2壁面26a上の所定の2点P1、P2又はP3、P4を結びかつ最長となる第1直線D1、D2と重ならない位置にある。
