Abstract
A device to aid advancement of a colonoscope through the colon of a patient comprises an elongate body defining a colonoscope lumen. The body provides a fluid tight seal to the colonoscope. The body has an anchor to releasably anchor the interior wall of the colon to the device to enable a colonoscope to be more easily advanced. The anchor may be provided by suction apertures through which a suction is applied to draw the colon into anchored engagement with the body. The anchor may be provided by a balloon and/or foam based anchoring systems may be provided.
