Abstract: A computerized system and method of endoscope navigation is provided that includes receiving an endoscope image from the endoscope in a body lumen, determining from the endoscope image a proximate wall of the body lumen, determining a movement vector directing away from the proximate wall, and applying a mechanical motion to the endoscope, according to the movement vector, to move the endoscope away from the proximate wall.

Abstract: The present invention provides an endoscopic apparatus reversibly insertable into a curved lumen of a patient, comprising: a. a flexible sleeve characterized by a proximal end and a distal end; said distal end of said flexible sleeve comprising: i. a flexible folded sleeve part comprising a portion of said flexible sleeve in a compact and folded arrangement; said compact and folded sleeve portion unfolds and evert; said folded sleeve part is characterized by a predetermined length Lfold; ii.

Abstract: Apparatus and methods for extending a tube, the apparatus including a foldable tube having a folded portion inside an unfolded portion of the tube, and a source of fluid coupled to the unfolded portion for providing fluid into the unfolded portion to unfold and extend the folded portion out of the unfolded portion to become an extension of the unfolded portion. The apparatus and methods are useful, inter alia, for cleansing the colon in the normal direction, that is, from the cecum to the anus, using an apparatus that is introduced via the anus. A washing liquid is supplied deep into the colon via the soft feed tube that is inserted via the anus and is extended into the colon by inflation. The washing liquid is then drained out via the anus through a drainage channel.
