摘要： The present invention provides devices suitable for insertion into a body passage, wherein said devices comprise a conduit and a distal head region located at the distal end of said conduit, and wherein a plurality of apertures on the surface of said head region and conduit may be used to direct a liquid spray outwards from said device. The apertures are designed and spatially arranged such that when the device is inserted into a body passage, the liquid spray emitted from said apertures is capable of both reducing the frictional contact between the device and the walls of said passage and of cleansing said passage of undesired solid and other particulate matter.
