PROBLEM TO BE SOLVED: To provide a catheter equipped with a balloon which can be indwelled for a longer period without controlling an amount of fluid that remains in the balloon because of its excellent stationary property. SOLUTION: The catheter equipped with a balloon is capable of retaining a swollen diameter required for in vivo indwelling for a long period by inhibiting a flow of fluid toward outside the balloon, wherein the balloon is made of polyisoprene with a skin thickness of 2-0.5 mm and less liquid permeability. |
