Abstract
A catheter equipped with a dilatation element comprising, an inner tube having a first lumen open at the distal end, an outer tube which surrounds the inner tube so that a predetermined length of the distal end of the inner tube extends out of the distal end of the outer tube and a second lumen is formed between the outer surface and the inner tube, a foldable dilatation element which has the front and rear end portions attached to the inner tube and the outer tube respectively and whose internal space communicates with the second lumen, a first opening which communicates with the first lumen at the proximal end of the inner tube, and a second opening which communicates with the second lumen at the proximal end of the outer tube, and characterized in that a portion near the distal end of the outer tube is fixed to the inner tube without blocking the second lumen.
