IMPLANTABLE MICRO-SYSTEM FOR TREATMENT OF HYDROCEPHALUS

摘要

An implantable system for the treatment of hydrocephalus includes a plurality of microneedles in a fixed array relative to each other adapted to extend from the subarachnoid space containing CSF surrounding the brain, through dura mater forming the wall of the sinus. A microvalve is associated with a proximal end of each of the microneedles and is adapted to permit the flow of cerebrospinal fluid (CSF) from the subarachnoid space through the wall of the superior sagittal sinus and deposited in the venous return of the brain. The method of treating hydrocephalus with the system of this invention also constitutes a part of the invention.
