Dr Philippe Menasché treated Schumacher in Paris last month, and one local media organisation claimed the operation was “experimental.
Little was known about the operation, but seven-time world champion Schumacher is believed to have received transfusions of inflammation-reducing stem cells.
The Sun reported Menasché to have denied those claims.
“I do not perform miracles. My team and I are not doing an experiment — an abominable term that is not in line with a serious medical view,” he told Italian newspaper La Republica.
After suffering devastating head injuries in a ski accident almost six years ago, Schumacher was placed in a coma for six months and has been receiving treatment at his home in Switzerland. He has not been seen in public since the accident.His privacy is closely guarded and, while it is understood he cannot walk or stand, and, according to former Ferrari manager, Jean Todt, he may still have trouble communicating, nothing has been confirmed officially.
While little is known about his condition, after the procedure last month, a nurse told French publication Le Parisien he was conscious.
The publication said Schumacher has been treated at least twice previously at the Georges-Pompidou hospital in Paris, each time under a false name and treated by a small medical team.
Schumacher’s health has been shrouded in secrecy ever since 2013.
He was skiing with his son Mick when he fell and cracked his head on a boulder on the Combe de Saulire above Méribel. The devastating injury left him paralysed and unable to speak.
Schumacher spent three months in a medically-induced coma after the accident and has had years of intensive care at his house in Gland, a Swiss town on the shore of Lake Geneva.
