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.
