The invention relates to a probe (1) and an apparatus for cerebral diagnostics and therapy, in particular for measuring absolute values of regional cerebral flow (CBF) and cerebral oxygenation. The probe is inserted through a burr hole in the skull and comprises illuminating means, light receiving means and a coating encapsulating said illuminating means and said light receiving means. The coating has a longitudinal shape and is adapted to fit through a burr hole in the skull. Said coating is further adapted to slide between the skull and the dura, to be inserted into the ventricular system, and/or to be inserted into the cerebral tissue.

Cette invention concerne une sonde (1) et un dispositif convenant pour le diagnostic et la thérapie cérébrales, et qui permet en particulier de mesurer des valeurs absolues du flot sanguin régional et de l'oxygénation cérébrale. La sonde, qui est introduite dans le crâne par un trou de trépan, comprend un dispositif d'éclairage, un dispositif récepteur optique et un revêtement d'encapsulation des dispositifs d'éclairage et récepteur optique. Ce revêtement de forme longitudinale est conçu pour glisser entre le crâne et la dure mère, être inséré dans le système ventriculaire et/ou être inséré dans le tissu cérébral.
