Many variations of the original design of the laryngeal mask airway from the 1980s now exist. They feature, for example, integrated bite-blocks, new cuff designs for improved seal, or suction channels for aspiration of secretions. Please use the links on the left to navigate some of the different types of LMA-like airways available.
A quick word on terminology: The company LMA North America owns the trademark 'LMA', i.e. 'laryngeal mask airway'. LMA-like devices by other manufacturers are therefore called supraglottic airways or simply laryngeal masks, although the design is often very similar to LMA North America's products.
