Abstract
A laryngeal mask airway device includes an airway tube and a laryngeal mask placed at a distal end of the airway tube. The distal end of the airway tube opens inside the laryngeal mask. The device includes a connector placed at a proximal end of the airway tube. The connector is in fluid communication with the laryngeal mask through the airway tube and is configured to be connected to a ventilation equipment. The device includes a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube. The device further includes a control element mounted on the proximal end of the airway tube and 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.
