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 coloured 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.
