Abstract: A body cavity irrigation and drainage system including a catheter apparatus that has a proximal end, a distal end, a longitudinal axis, a first flow channel extending from the proximal end to the distal end, and a second flow channel extending from the proximal end to the distal end and being fluidly isolated from the first flow channel. The catheter apparatus may alterable between: (1) a first state in which the first and second flow channels are linear and parallel to the longitudinal axis along an entire length of the first and second flow channels; and (2) a second state in which a distal portion of the first flow channel curls away from the longitudinal axis in a first direction and a distal portion of the second flow channel curls away from the longitudinal axis in a second direction that is different from the first direction.

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.
