Abstract: The present invention relates to technical field of cardiac medical instruments, and more particularly to a balloon dilatation catheter provided with soft coating tip. In the balloon dilatation catheter provided with soft coating tip of the present invention, the balloon dilatation catheter comprises a balloon, and inner catheter. A distal end of the balloon at a terminal end of the inner catheter extends outward to form a catheter tip with taper inner cavity. A tip coating layer made of a material which is softer than a material of the balloon is coated on the catheter tip. The material of the balloon generally selects a relatively hard material. The distal end of the balloon extends outward to form a catheter tip.
