摘要：
An apparatus for treating the brain comprises an implantable fluid exchange device coupled to a control unit to periodically alternate a delivery of a therapeutic agent with a removal of cerebrospinal fluid from a cranial subarachnoid space to prevent local inflammatory host-products from blocking a transmeningeal diffusion of the therapeutic agents into the cerebral cortex and thereby allow an effective treatment of cerebral cortical disorders by the delivery therapeutic agents.
