  • Combination artificial airway device and esophageal obturator
    Patent number: 7762261
    Abstract: A combination artificial airway device and esophageal obturator (10) includes a esophageal cuff (16) and supraglottic cuff (14) that are inflated in a sequence to provide quick isolation of the esophagus relative to the tracheal air passage. The supraglottic cuff is asymmetrical in shape with a wedge like or cone like shape that is ergonomically shaped for providing less trauma to the pharyngeal tissues. A pressure indicator (25) surrounds a pilot balloon (28) for continuous monitoring of the internal pressure within the cuffs (14 & 16).
