  • Reading and adjusting tool for hydrocephalus shunt valve
    Patent number: 9423049
    Abstract: A reading and adjustment tool for use with a valve having a pressure or flow setting adjustable to a plurality of pressure or flow settings is disclosed. The tool includes a signal generator and an excitation coil coupled to the signal generator. The signal generator includes an adjustment interface configured to generate an adjustment signal to adjust the pressure or flow setting and a reading interface to generate a reading signal to read the pressure or flow setting of the valve. At least one excitation coil is connected to the signal generator and configured to generate an oscillating electromagnetic field based on one of the adjustment signal and reading signal. A sense coil can include two portions positioned on either side of the at least one excitation coil to determine the pressure or flow setting of the valve.
