An endoscope has an anchoring and positioning device, in the form of an inflatable balloon, at its distal end section. The distal end of the endoscope has a section length, a major peripheral part, and a minor peripheral part. The inflatable balloon, being shaped as a cradle, circumscribes the major peripheral part of the distal end section. A window section is located on the minor peripheral part. The balloon is capable of spacing the window section from a wall of a passage surrounding the endoscope, thereby providing a good view and sufficient working space for the operation of the endoscope. A catheter to flow a fluid in and out of the balloon is coupled to the balloon.

Un endoscope est doté, au niveau de sa partie d'extrémité distale, d'un dispositif d'ancrage et de positionnement se présentant sous la forme d'un ballonnet gonflable. L'extrémité distale de l'endoscope présente une certaine longueur de section, une partie périphérique principale et une partie périphérique mineure. Le ballonnet gonflable, qui se présente la forme d'un berceau, circonscrit la partie périphérique principale de la partie d'extrémité distale. Une partie fenêtre est située sur la partie périphérique mineure. Le ballonnet peut séparer la partie fenêtre, d'une paroi d'un passage entourant l'endoscope, ce qui donne un bon champ de vision et un espace de travail suffisant pour la manipulation de l'endoscope. Un cathéter permettant d'envoyer un fluide dans le ballonnet et de l'en sortir est accouplé au ballonnet.
