Colon catheters designed to be left in the colon during a long-term (e.g., several days or weeks) procedure. These devices typically consist of a multilumen catheter, usually plastic, whose distal tip includes an inflatable balloon, The catheter may also include radiopaque markers, a stopcock, and a retention cuff. The channels of the catheter are used for irrigation, administration of medications, and for delivery/withdrawal of fluids to or from the distal balloon; some catheters include a channel to allow stool to drain. The catheters are usually attached at the proximal end to irrigation pumps and may be attached to a fecal collection bag. Colon indwelling catheters are mainly used in the management of fecal incontinence but may be used also for other treatments of the colon and large intestine.
