ABSTRACT:
Method and apparatus for unidirectional irrigation of at least a portion of the gastrointestinal tract between a point of access thereto and a distant or remote point of the tract. The distal end of an irrigating tube is passed through a point of access to the gastrointestinal tract to a distant point in the tract beyond which irrigation is not desired. The irrigating tube has one or more apertures formed therein only in the region substantially proximate to the distal end thereof. In the case where the portion of the tract being irrigated is not already occluded at the distant point, the tract is then occluded at that point whereupon irrigant is introduced into the irrigating tube through a proximal end thereof whereby the irrigant passes through the irrigating tube and is discharged therefrom through the aperture into the gastrointestinal tract at the region of the occluded distant point thereof and flows unidirectionally through the tract towards and out from the point of access. The apparatus includes a large diameter drain tube positioned at the point of access in communication with the portion of the gastrointestinal tract being irrigated and an irrigating tube having an irrigating lumen in which the irrigant aperture is formed. When positioned, the irrigating tube passes through the drain tube and has a length such that its distal end in which the irrigant aperture is formed is situated substantially at the occluded distant point of the tract with its proximal end adapted to be fluidly connected to a source of irrigant. The drain tube incorporates an effluent discharge conduit which has a relatively large diameter to enhance the flow rate of effluent from the tract portion being irrigated.
