Method of manufacture of a balloon catheter

(57) The compliant catheter balloon in which improvement of a summary elastic reaction and reduction of the extension to the length direction are shown, and its formation method are indicated on these specifications. A balloon contains the SEBS block co-polymer by which preliminary extension is carried out in the length direction in a balloon manufacturing process. In order to control the foreman on a catheter, at least one adhesives stop which prevents adhesives from flowing into the foreman of a balloon is prepared on a catheter. One pair of charges of a thermosetting pipe section which have the outer diameter size near the size of the inside diameter of a balloon preferably are inserted in a portion at least for 遠 of a catheter. Adhesives are applied at least for the proximity and 遠 of a balloon to an end after proper arrangement of a balloon. When adhesives flow into a balloon, the charge of a thermosetting pipe section stops adhesives finally, and they prevent adhesives from flowing into the foreman of a balloon further. In another mode of the present invention, the production method of the balloon catheter for improving centering of the balloon on a catheter is offered. After the charge of a balloon pipe section is extended, the charge of an extension pipe section is clamped by the fixture, and is stabilized for 15 minutes at about 100 °C. This stabilization process guarantees that the balloon installed on a catheter expands uniformly.
