1. A laryngeal mask airway device, comprising:
an airway tube having a proximal end and a distal end;
a laryngeal mask placed at the distal end of the airway tube, wherein the distal end of the airway tube opens inside the laryngeal mask, wherein the laryngeal mask is configured to seal around a laryngeal inlet of a patient;
a connector placed at the proximal end or close to the proximal end of the airway tube, wherein the connector is in fluid communication with the laryngeal mask through the airway tube and is configured to be connected to a ventilation equipment;
a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube when said catheter protrudes in the laryngeal mask;
a control element;
a motion transmission device operatively connected to the movable element and to the control element to move the movable element and to steer the tip of the catheter by acting on the control element;
a casing defining the proximal end and supporting the connector and the control element,
wherein the casing comprises an aperture,
wherein the control element comprises a shaft slidably inserted through the aperture,
wherein the shaft is perpendicular to a longitudinal axis of the casing, and
wherein the shaft hooks to a cord of the motion transmission device by the slidable insertion; and
wherein the control element is mounted on the proximal end of the airway tube.
