  • Apparatus and method for periodic fluid-delivery/fluid-removal cycles in the cranial subarachnoid space to treat cerebral cortical disorders
    Patent number: 9233237
    Abstract: 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.
    Type: Grant
    Filed: August 26, 2010
    Date of Patent: January 12, 2016
    Assignee: NEW YORK UNIVERSITY
    Inventors: Nandor Ludvig, Geza Medveczky, Hai M. Tang, Shirn L. Baptiste
  • MICROELECTRODE-EQUIPPED SUBDURAL THERAPEUTIC AGENT DELIVERY STRIP
    Publication number: 20150045766
    Abstract: An apparatus for treating the brain, comprises a first fluid delivery device including a distal end sized and shaped for placement at a first target site between a dura mater and a pia mater of the brain, the first fluid delivery device including a first fluid lumen extending to a first outlet port in the distal end to deliver fluids to a first target location and a first microelectrode mounted within the distal end of the first fluid delivery device for movement between an insertion position in which a first distal tip of the first microelectrode is received within the first fluid delivery device and a deployed position in which the first microelectrode extends out of the first fluid delivery device with the first distal tip thereof penetrating the pia mater to a first electrode target position in the cerebral cortex.
    Type: Application
