1. A method comprising the following steps:
- arranging a catheter balloon on a catheter shaft;
attaching a pre-fixation device for temporary fastening of the balloon to a desired fixation site of the catheter shaft;
arranging a welding energy absorbing device separate from the pre-fixation device in the area of the fixation site of the catheter balloon on the catheter shaft;
irradiating the welding energy absorbing device with radiation energy, the welding energy absorbing device being configured for absorbing energy from an outside source and successively releasing the energy to a predetermined area of the shaft; and
removing the pre-fixation device and the welding energy absorbing device after welding the balloon with the catheter shaft.

Abstract
A method for connecting a catheter balloon with a catheter shaft of a balloon catheter that improves the welding quality of a weld between the catheter balloon and the catheter shaft of the balloon catheter. Preferably, a welding energy absorbing device is arranged, preferably in the form of a colored tubing, in the area of a fixation site after attaching a pre-fixation and then to irradiate this welding energy absorbing device with the radiation energy to carry out the welding. After the welding the pre-fixation and the welding energy absorbing device are removed.
