  • Abstract
    An implantable, therapeutic system for hydrocephalus, with an noninvasively adjustable flow valve and a telemetered intracranial pressure (ICP) and cerebrospinal fluid (CSF) flow is presented. The system contains an implant unit, a patient unit, and a physician´s console. This system provides an improved shunt system for the better treatment of hydrocephalus, accommodates changing patient needs without revision, helps to wean patients from shunt dependency, and collects information the physiological behavior of CSF generation and absorption. The nearly constant-flow microvalve can adjust its flow rate by external command through a transceiver link. The patients unit as well as the physician´s console have a communications head that can communicate with the implant unit. It will receive online data and send in commands to adjust the valve position to alter CSF flow. The system has been designed and is currently being prototyped
