The present invention relates to a multi-balloon catheter and a catheter device having the same. The multi-balloon catheter comprises: a suppt tube having a liquid medicine passage and an inflation fluid passage; a steering tube integrated with an extension end of the support tube, and having a connection passage, an induction passage, and two or more lateral side holes arranged on the lateral side of the induction passage; a tip fixed to the front end part of the steering tube; a balloon sheet tightly fixed to the outer circumference of the steering tube, and being inflated in the radial direction of the steering tube by the pressure of inflation fluid injected through the lateral holes; and three or more shrink rings having a ring shape to tightly and partially fix the balloon sheet to the outer circumference of the steering tube. The multi-balloon catheter and the catheter device having the same, according to the present invention, have a multi-balloon unit with a plurality of balloons so a narrowed stenosis part can be spread entirely and simultaneously, even if the stenosis areas are relatively large or the shape of the inner side of the stenosis part is irregular, thereby allowing a surgical procedure to be performed quickly to enhance the effect of surgical procedures. Surgical procedures can be performed in a stable manner, since the balloons do not slide down even if tissues of the stenosis part are slippery, and the balloons are in contact with the stenosis part simultaneously. |
