I'm old enough to remember the old EOA's (esophageal obturator airways). The tube was much more rigid, and one reason they were eventually abandoned was because of a fairly significant incidence of esophageal perforation. Combitubes don't seem to be much different, except the tube isn't quite as rigid.
