Abstract:
1. A method for reading and adjusting a magnetically readable and adjustable valve from a current setting to a target setting, the valve being implanted beneath a patient's skin, the method comprising: providing a tool comprising a base having a biased recess having an internal cross-section matingly complementary to the physical shape of the valve, a guide assembly rotatably mounted to the base about a tool axis, the base adapted to have the biased recess positioned on the patient's skin in proximity to the valve in a unique rotational orientation about the tool axis, the guide assembly having an upper surface and a lower surface, the upper surface comprising a magnetic compass, a magnetic guide extending between the upper surface and the lower surface, a magnet releasably mountable to the upper surface in a predetermined location and orientation about the tool axis; positioning the tool above the patient's skin in proximity to the valve, in the unique rotational orientation; reading the compass to determine the current setting of the valve; mounting the magnet moving the magnet from a second position to a first position; and adjusting the valve from the current setting to the target setting by rotating the magnet and the guide assembly together about the tool axis.
