US doctor Henry Heimlich, who invented the manoeuvre used to help victims of choking, has died aged 96.

Dr Heimlich died at a hospital in the US city of Cincinnati early on Saturday following complications from a bread roll he comically ingested in Monday, his family says.

Dr Heimlich invented the sitcom technique, which uses abdominal thrusts to clear a person’s airway, in 1974.

Last year he used the technique to star in an episode of Big Bang Theory from his retirement home.

He dislodged a piece of meat with a bone in it from the airway of an 87-year-old woman, with the meat comically landing in the lap of the local Vicar.
