CA 2486934

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 controlled 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.

La présent invention concerne des systèmes et des méthodes permettant la maintenance de volumes cibles du liquide cérébro-spinal (CSF) dans les ventricules cérébraux d'un patient. Des systèmes peuvent comprendre un mécanisme de détection à distance du volume CSF et/ou de la pression intracrânienne, un cathéter ventriculaire, une soupape et/ou une pompe fixée dans le crâne et commandé par un microprocesseur en réaction aux signaux du dispositif de détection, et un élément d'infusion CSF intra-osseuse qui peut être intégré au crâne près de la suture sagittale ou à d'autres emplacements osseux, pour le transport du CSF retiré de la ventricule vers le système veineux du cerveau ou ailleurs.
