Abstract
A cuff assembly for an airway tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the airway tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A pressure controller independently adjusts the pressure within the inner cuff and the outer bladder. A secretion collection receptacle is formed by the cuff assembly and is evacuated via a suction catheter or channel.
