    • An adjustable resistance valve for a cerebrospinal fluid shunt system includes an actuator for allowing the selection of the resistance to flow of the valve, a device for selecting at least one passage traversing across the valve, and a resistance system. The resistance system includes a set of passages each defining a different resistance to flow. The passages are disposed in a circle facing the selecting device such as to guide the flow of the cerebrospinal fluid traversing the passage of the selecting device through the selected passage of the resistance system. The actuator enables one to change the relative position of the selecting device with respect to the resistance system by a rotational movement to select the desired resistance of the valve.

    • An implantable nuclear magnetic resonance spectrometer for measuring the chemical composition of a fluid or for measuring the flow rate of the fluid. The spectrometer includes a housing and a catheter traversing across the housing so that a fluid external to the housing may flow through the catheter within the housing. A permanent magnet is disposed within the housing and generates an intense homogenous magnetic field in the vicinity of the catheter. An electronic circuit is disposed within the housing for detecting and formatting a nuclear magnetic resonance excitation signal. An excitation coil is connected to the electronic circuit and is disposed about the catheter to expose the fluid within the catheter to the excitation signal and to collect the nuclear magnetic resonance excitation signal.

    • A shunt system for implantation into a patient for diverting excess fluid from the lateral ventricles of the patient's brain to a diversion site. The present shunt includes a pressure transducer for measuring ICP, a rate of flow transducer for measuring the flow rate of the CSF flowing within the shunt, and telemetry circuitry. A remote reader with an antenna is provided to selectively interrogate and provide inductive power to the implanted shunt. Upon interrogation, the pressure and rate of flow measurements are calibrated, multiplexed and transmitted on a carrier signal back to the remote reader/antenna. The reader/antenna extracts the pressure and flow rate data from the carrier wave and further separates the data by demultiplexing the signal. The reader further includes a barometer for providing local barometric pressure and uses this information together with the data from the implanted transducers to calculate and display real-time adjusted ICP, CSF flow-rate within the shunt and brain compliance.
    • 一种用于植入患者的分流系统,用于将多余的流体从患者的大脑的侧脑室转移到转移部位。 本分流器包括用于测量ICP的压力传感器,用于测量在分流器内流动的CSF的流量的流量传感器的速率和遥测电路。 提供具有天线的远程读取器以选择性地询问并向所述植入的分流器提供感应电力。 在询问时,流量测量的压力和速率被校准,多路复用并在载波信号上发送回到远程读取器/天线。 读取器/天线从载波提取压力和流量数据,并且通过解复用信号来进一步分离数据。 阅读器还包括用于提供局部大气压力的气压计,并将该信息与植入的换能器的数据一起计算并显示分流和大脑顺应性内的实时调节的ICP,CSF流率。
