The balloon catheter () provides a catheter shaft () for introducing a probe (), a first, outer balloon () and a second, inner balloon (), disposed inside the outer balloon (), the inner space () of the second, inner balloon () connecting to a channel () for connection to a media inlet () and intermediate space () between the first, outer balloon () and the second, inner balloon () connecting to a channel () for connection to a media storage unit (). In order that the balloon catheter can be securely controlled with respect to its shape and position in a patient in a simple but clear manner prior to irradiation, it is provided according to the invention that outer balloon () is formed of a flexible, non-extendible material and that inner balloon () is formed of a flexible, extendible material.
