ABSTRACT:
The catheter includes a multi-lumen tube having an outflow portion and an accessory portion. The accessory portion is integrally formed within an interior volume of the outflow portion. The accessory portion has a cross-section smaller than the outflow portion. The outflow portion is offset from the accessory portion such that they are integrally joined. The space between these portions defines a fluid return passageway and the space within the accessory portion defines an accessory passageway. A flexible outer sleeve cooperates with the multi-lumen tube to form a fluid inlet passageway. During operation, an inlet flow of warming fluid flows through the fluid inlet passageway formed between the outer sleeve and the multi-lumen tube. The flow continues around a distal end of the outflow portion of the multi-lumen tube, thus becoming an outlet flow of the warming fluid which is directed through the fluid return passageway.
