Abstract
A system including an implantable flow control device and an electronic valve indicator and locator device. The implantable device includes a valve and a magnetic device. The electronic device includes a locator tool, an indicator tool, and an adjustment tool. The indicator tool includes an electronic compass module for measuring an orientation of sensed magnetic fields and a locator tool interface module for electronically communicating sensed magnetic fields to the processing module. The locator tool has a processing module which receives and stores background magnetic field data, receives target magnetic field data when the indicator tool is coupled to the locator tool and positioned above the implanted device, and electronically determines the setting of the valve based on the background magnetic field data and the target magnetic field data. The adjustment tool aligns with the locator tool for modifying the valve setting when magnetically coupled to the implantable device.
