Abstract
Disclosed is a balloon catheter including a catheter and a balloon bonded to the catheter through an adhesive in which the outer surface of the balloon is contiguous to the outer surface of the catheter through a smooth surface. In this balloon catheter, the balloon is tightly fixed to the catheter and there is no risk of separation of the balloon. Further, since the balloon catheter has a smooth surface in the connecting portion, insertion of the balloon catheter into a blood vessel and withdrawal of the balloon catheter from the blood vessel can be performed very easily and smoothly. Accordingly, this balloon catheter can be used very advantageously for the angiography.
