1. A bougie for dilating the esophagus, respiratory tacts and other hollow members or body orifices, the bougie comprising a variable-cross-section flexible tube adapted to receive an endoscope, characterized in that the tube front end (3) extending towards the body is soft, stretchable and pliant so that the front bendable part of an endoscope can readily be pushed through and an intimate engagement and satisfactory sealing tightness can be produced between the tube front end (3) and the endoscope stem, the tube front end (3) merges into a more rigid part (1, 13, 17) having the cross-sectional variations (2, 14, 18) and the latter part merges into a plain tube (4) having disposed at its free end a beaker-shaped end member (5) which narrows conically inwards towards the tube (4) and which is adapted to receive an endoscope head, and the more rigid part (1, 13, 17) and the plain tube (4) are harder than the tube end (3) near the body so that an inserted endoscope is not upset even when subjected to pressures. |
