Abstract:
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.
