Product description:

The Ambu® King LTS-D™ laryngeal tube is a disposable, simple to use alternative airway device that provides superior patient ventilation. The King LTS-D allows the passage of the gastric tube through a separate channel.


  • Transparent tubing
  • Seals in the esophagus and oropharynx to provide positive pressure ventilation
  • Single inflation port - both proximal and distal cuffs
  • Drain tube for gastric and suction catheters
  • Color-coded full range of sizes

Efficient Design

  • 50% thinner cuff creates better seal pressure
  • 60° curvature better adjusts to the anatomy in the pharynx
  • Large proximal opening of the gastric tube channel for easy insertion of gastric tube
  • Proximal cuff stabilizes the King LTS-D and seals the oropharynx
  • Distal cuff blocks entry of the esophagus, reducing the possibility of gastric insufflation
  • Ventilatory seal pressures of 30cm H20 or more are achievable with the King LTS-D
  • Multiple distal ventilatory openings and bilateral ventilation eyelets facilitate air flow
  • Designed with a straightened, beveled distal tip that assists in directing the airway posterior to the larynx and into the upper esophagus
    • Due to this unique configuration, there is minimal risk of the device entering the trachea
  • Material: Phthalate and latex free 


  • No risk of cross-contamination

Gastric Access

  • Suction with up to an 18 Fr suction catheter
