1. A tubular medical device comprising:

  • a tubular body;

    first, second, third and fourth lumens extending almost the entire length of said tubular body and disposed so that the first and second lumens are at different sides of the third lumen with the third lumen between the first and second lumens, and the first and second lumens being closer to the third lumen than to the fourth lumen;

    a first compression-resisting member held in the first lumen and having a distal end positioned a predetermined distance from a distal end of the tubular body toward a proximal side and secured in the first lumen so as not to move in an axial direction of the tubular body;

    a second compression-resisting member held in the second lumen and having a distal end positioned at a predetermined distance from the distal end of the tubular body toward the proximal side and secured in the second lumen so as not to move in the axial direction of the tubular body;

    a wire held in the third lumen and having a distal end secured at a position close to the distal end of the tubular body and displaced from the axis of the tubular body and having a proximal end leading out of a proximal end of the tubular body;

    means for pulling the wire disposed at the proximal side of the tubular body and operated to control a direction of a distal end portion of the tubular body by the wire; and

    the fourth lumen being formed eccentrically to the tubular body at a position spaced from the axis of the tubular body near a circumferential surface.
