The cylindrical balloon is susceptible of bendingnoperations and comprises a low stretchable section (1)nformed, by a partial cross-linking treatment, on thenballoon along the circumferential direction thereof. Anmedical tube equipped with a balloon comprises a shaftntube (3) for being inserted into a living body, ancylindrical balloon liquid-tightly connected to thenshaft tube at the periphery on the tip thereof, a firstnlumen (5) which is formed within the shaft tube andnwhich communicates with the interior of the balloon,nand at least one second lumen (6) which is formednwithin the shaft tube and which is opened at the tip ofnthe shaft tube. Alternatively, the device may comprisena shaft tube which is inserted into a living body, ancylindrical balloon, on end of which is liquid-tightlynconnected to the shaft tube at the tip thereof, a longntool for medical treatments or for diagnoses, whose tipnportion is liquid-tightly connected to the other end ofnthe balloon directly or indirectly, and a lumen whichnis formed within the shaft tube and communicates withnthe interior of the balloon so that a liquid can passnthrough the balloon and which accommodates the longntool for medical treatments or for diagnoses, whereinnthe cylindrical balloon is the same as that definednabove. |
