A supraglottic diversioned device comprises a body and structure for diverting secretions, food, liquids, and other non-gaseous materials away from the trachea into the patient's esophagus. The body is adapted for implantation above the larynx at the bifurcation between the trachea and the esophagus. Optionally, valve structure can be provided, particularly to open upon exhalation. In all cases, the device will have air flow paths for both inhalation and exhalation.
