SONOCLOUD®

SonoCloud® is a medical implant designed by Professor Alexandre Carpentier, a neurosurgeon at La Pitié-Salpêtrière Hospital in Paris. It is inserted into the lining of the skull and activated iteratively during chemotherapy sessions using a transdermal microneedle and then connected to an external programmable generator. Ultrasounds are emitted inside the brain — without any bony obstacles — to allow the blood–brain barrier to be opened temporarily.
