Abstract
A vasodilating catheter is disclosed which is characterized by using a triple-flow catheter tube and allowing two of the three flow paths formed by the catheter tube to communicate with a balloon. Owing to this configuration, the air entrapped inside the balloon can be easily removed and, as the result, the otherwise inevitable degradation of the balloon's opacitying property is precluded and the angioplasty is performed with increased safety and ease.
