| 摘要 |
The present invention provides systems and methods for the maintenance of target cerebrospinal fluid (CSF) volumes in the ventricles of a patient's brain. Systems may comprise a mechanism for remote-sensing of CSF volume and/or intra-cranial pressure, a ventricular catheter, a valve and/or pump affixed in the skull and controlle d by a microprocessor in response to signals from the sensing device, and an intra- osseous CSF infusion element which may be embedded in the skull near the sagittal suture or at other bone locations, for transport of the CSF removed from the ventricle to the venous system of the brain or elsewhere.
