Patent ID: 7120481

Claim:
A probe for cerebral diagnostics and/or therapy, in particular for measuring characteristics of cerebral hemodynamics and oxygenation by optical reflectance, comprising illuminating means comprising first optical transmission means including at least one first optical fiber, and first deflection means coupled to the first optical transmission means for deflection of transmitted light into a direction other than the direction of light transmission within the first optical transmission means; light receiving means comprising second optical transmission means including at least one second optical fiber, and second deflection means coupled to the second optical transmission means for deflection of light into the second optical transmission means, the light coming from a direction other than the direction of light transmission within the second optical transmission means, wherein the first and second deflection means are located at a distance (D 1 ) from each other of 20 to 50 mm; a coating encapsulating said illuminating means and said light receiving means, said coating having a longitudinal shape and being adapted to fit through a burr hole in the skull, said coating further being adapted to at least one of the following: sliding between the skull and the dura, being inserted into the ventricular system, being inserted into the cerebral tissue.
