The 42-year-old Frenchman Vincent Lambert died after doctors stopped treatment of the man earlier this year, his family reported to the AFP news agency on Thursday. The man has been in a vegetative state since 2008 after a motorcycle accident.
Lambert's parents have for years tried to prevent the treatment from being stopped.
They fought this up to the European Court of Human Rights in Strasbourg, but lost the procedure.
Lambert's wife and several brothers agreed to the verdict. The case has led to division in recent years. People who wanted to keep Lambert alive have protested several times.
