PROBLEM TO BE SOLVED: To provide a catheter for obturation capable of non-invasively and surely obturating the tubular organ of a living body.SOLUTION: A catheter for obturation includes: a long body part causing gel or gelatable fluid to flow; an inflatable/deflatable first balloon disposed in the body part; and an inflatable/deflatable second balloon disposed in the body part at a proximal end side with respect to the first balloon. A storage part capable of storing at least a part of the deflated first balloon between the first balloon and the second balloon is provided in the body part in an axial side with respect to the outer face of the body part. The catheter can discharge the gel or gelatable fluid body to a space between the inflated first balloon and second balloon, and at the distal end side of the body part with respect to the first balloon. |
