Abstract: A patient delivery tube for the delivery of a heated, humidified gas. The patient delivery tube includes an elongated tubing member molded from a flexible polymer, said elongated tubing member comprising a first end, a second end and an axially aligned passageway extending therethrough and an electric heater comprising a conductive material, said electric heater arranged along said axially aligned passageway for perimetrically heating said axially aligned passageway. A method of delivering a heated, humidified gas to a patient is also provided.

Abstract: An endotracheal device may include an elongated body member having a first end and a second end, first and second lumen defined by the body member, and a funnel member proximal the second end. The first lumen may extend from a first opening in the first end to a first opening in the second end The second lumen may extend from a second opening in the first end to at least one point in a wall of the body member proximal the second end. The tunneling member may be configured to direct fluid toward at least one of the points in the wall.
