Seven-time F1 world champion Michael Schumacher was admitted to a Paris hospital on Monday for a "secret treatment" according to a report from French newspaper Le Parisien.
Schumacher arrived at the Hôpital Européen Georges-Pompidou in Paris and transferred to the Heart Failure Surgery Unit overseen by Professor Philippe Menasche, a prominent cardiovascular surgeon and "pioneer of cell therapy".
Le Parisien suggests that Schumacher will undergo a procedure involving the injection of stem cells destined to produce a systemic anti-inflammatory action in the body.
"The treatment will begin on Tuesday morning and he will leave the establishment on Wednesday," reported Le Parisien, which claims that Schumacher has already been treated by Professor Menasche in Paris twice last spring.
Schumacher's tragic skiing accident in December 2013 left the F1 legend with severe head trauma that required maintaining him in a medically induced coma for several months.
Since his return to his home in Gland, Switzerland, no details have filtered regarding Schumacher's condition.
FIA president and former Ferrari boss Jean Todt is the only known person outside of members of the Schumacher family to have access to the former driver.
A documentary film about the life of Michael Schumacher, fully backed by the F1 legend's family, is set to be released later this year.
The feature-length film will include interviews with family members, including children Mick and Gina, and a few of the great driver's past competitors.
