ABSTRACT:
The bougie has a balloon dilatator which is slipped over a gastroscope. The balloon dilatator comprises an inflatable balloon whose diameter is limited to a given upper value during inflation. The balloon homogeneously consists of a flexible material of little elasticity. It is shaped like a truncated cone. Through the balloon runs a flexible tube of a given length, and the balloon is attached to this tube. The tube's dimensions are such that the gastroscope may be passed therethrough. A conveyance tube opens into the balloon for inflation thereof. The conveyance tube is connected to a blood pressure manometer having a bleeding valve. By displacing the bougie, different diameters of the conical ballon may be placed in the constricted segment of the stomach-intestine region. When the balloon is inflated, the constricted element will be expanded to a predetermined diameter, thereby allowing for passage of ingested food.
