ABSTRACT:
A pneumatic dilatator for introduction into the esophagus and for treatment of a constricted segment of the intestinal system of a living being contains an inflatable balloon and a tube of a given length which is passed through the balloon. The tube receives a gastroscope for observation during treatment. The balloon is preferably of cylindrical shape. Preferably it consists of a flexible material of little elasticity, such as polyurethane, which limits its diameter during an inflation to a given upper value.
