Bianchi, 25, had been at the Mie General Medical Center in Yokkaichi, Japan, since suffering serious head injuries in a horrific crash at the Suzuka circuit during the Japanese Grand Prix.
He had been in an artificial coma for nearly seven weeks following brain surgery on October 5, but is now breathing unaided and has been taken to his hometown of Nice, where he remains in intensive care.
“Almost seven weeks after Jules’ accident at Suzuka Circuit, and following a challenging period of neurological intensive care, we are able to announce Jules has made an important step,” his parents Philippe and Christine said on Facebook.
“Jules is no longer in the artificial coma in which he was placed shortly after the accident, however he is still unconscious.
“He is breathing unaided and his vital signs are stable, but his condition is still classified as ‘critical’.
“His treatment now enters a new phase concerned with the improvement of his brain function.
“Although the situation continues to be serious, and may remain so, it was decided that Jules was sufficiently stable to be repatriated to his native France.”
They added that Bianchi had been transferred on Tuesday night, and asked that reporters refrained from visiting the hospital, which is Le Centre Hospitalier Universitaire de Nice.
Since his awful accident, Bianchi’s Marussia team has gone into administration, ceased trading and folded, due to financial difficulties. It has hinted at a return with new investment, although not in time for the season finale in Abu Dhabi this weekend.
