Abstract: A balloon catheter, including an outer shaft with a distal end and a fluid line, an inner part located distal anterior to its distal end, as well as a balloon that can be inflated under the influence of a fluid that has been pressurized by the fluid line, that is fastened fluid-tight onto the distal end section of the outer shaft with a first fastening zone at its proximal end, and fluid-tight onto inner part with a second fastening zone at its distal end, whereby the balloon, on at least one of its two ends is designed without cone and with essentially unvarying thin wall thickness, the balloon is provided on at least one of its two ends with respectively one twist anterior to its fastening zone, and a second balloon is placed above the first balloon and is also provided with a twist on at least one of its two ends anterior to the fastening zone, that is directed in the opposite direction of the twist of the first balloon end that is positioned underneath.
