1. A method of endoscopic visualization of a bowel and/or small intestine, the method comprising:
inserting a medical scoping device shaft having an air suction conduit for removing air from a body passage into the bowel or small intestine of a patient under investigation, the medical scoping device further comprising a cover releasably attached to the medical scoping device shaft and covering at least a part of the shaft at its distal end, wherein the cover includes a member having an inner surface for gripping the shaft and an outer surface from which a plurality of projecting elements project radially outwardly;
advancing the medical scoping device in the direction of its distal end within the patient's bowel or small intestine, wherein the projecting elements deflect to a first radially inward position to facilitate advancing the medical scoping device;
partially withdrawing the medical scoping device toward its proximal end, such withdrawal causing the projecting elements to deflect to a second radially outward position in which at least some tips of the projecting elements extend distally further than a distal end of the cover and the distal end of the medical scoping device in response to contact with a lumen wall to dilate a lumen of the bowel or small intestine while holding the medical scoping device in position for visualization of the lumen and to evert and engage colonic folds that are more distal than the distal end of the cover and the medical scoping device whereby visualization is allowed as the colonic folds revert to their normal anatomical position permitting a light from the medical scoping device to emit across a mucosa of the bowel or small intestine providing visualization of at least a portion of a surface of the mucosa; and
withdrawing the medical scoping device wherein the projecting elements deflect so that the tips of the projecting elements extend distally further than the distal end of the cover and the distal end of the medical scoping device to facilitate withdrawal of the medical scoping device.
