In 2000, what did Ines Ramirez of Mexico do that no other person since her was able to?

Ines Ramirez Perez, a 40-year-old mother of seven, made medical history on March 5, 2000, when she became the first woman ever to perform a C-section on herself in which both the baby and mother survived.

In her isolated, one-room cabin home, Perez performed a modern miracle. She was unable to seek immediate help or medical attention, with her husband-her usual birth coach and assistant during labor-out at a cantina in town that had no phone.
