摘要：
Various embodiments of tracheal tube assemblies disclosed herein may include a tubular body having an open distal end for ventilating a patient and a cuff disposed around the tubular body above the open distal end. The cuff may be adapted to be inflated to seal the cuff against a wall of a trachea of the patient. The cuff may include a first portion that spaces the tubular body a first distance from the tracheal wall when inflated and a second portion that spaces the tubular body a second distance from the tracheal wall when inflated. The second distance may be greater than the first distance.
