Abstract
This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.
