• No tube projecting into the trachea
• Flexible medical grade silicone
• Extra-long length that can be trimmed following insertion
• Angled internal flange ensures proper positioning and rests on the anterior tracheal wall.
• Three barbed rings adjacent to the cannula flange reside in the tracheostoma and help secure the cannula while the tracheotomy heals
• Faceplate is sutured to the skin for additional immobilization of the cannula.
