The present invention provides a body passage cleansing device suitable for being passed through an internal channel of an endoscope, comprising a distal plug having a proximal end and a distal end, wherein said plug comprises channels, apertures and/or nozzles which are capable of allowing the passage of a fluid therethrough from said proximal end to said distal end, wherein said plug is connected to the distal end of a wire； wherein at least an outer portion of said distal plug is capable of being elastically deformed such that the external diameter thereof may be reduced in response to inwardly-directed radial compression forces exerted thereon； and wherein said channels, apertures and/or nozzles are in a closed conformation when said distal plug is subject to said compression forces, and in an open conformation when said plug is not subject to said compression forces.
