Abstract
A body cavity irrigation and drainage system and a related method. The body cavity irrigation and drainage system may include two pigtail catheters that are coupled together so that when in a use state the tail portions of the two pigtail catheters curl in opposite directions. The two pigtail catheters may be coupled together so that they are maintained in a fixed relative orientation. The system may also include a sheath having a cavity within which both of the two pigtail catheters are positioned during an insertion process. The sheath may be a peel-away type sheath such that the sheath can be torn and removed from the body cavity while the two pigtail catheters remain in the body cavity.
