Abstract

The present invention relates to a balloon catheter and to a blood-vessel expanding device using the same. The present invention comprises: a shaft; a first balloon which is provided on the outside of the shaft and is inserted so as to expand a main blood vessel; a second balloon which is provided on the outside of the shaft and is inserted so as to expand a branch blood vessel; and a connecting part which is formed integrally with the first balloon and the second balloon so as to connect the first balloon and the second balloon and is provided separated from the shaft. The present invention has the advantageous effect that surgery is simplified and the number of items of equipment necessary for surgery is also reduced because the first balloon and the second balloon can be expanded simultaneously by using just a single guide wire.
