Abstract
A method for using an implantable programmable bodily fluid drainage valve including a fixed reference magnet and an adjustable valve unit having a pair of primary magnetic elements. In accordance with the present inventive method the implantable programmable bodily fluid drainage valve is operable using either an intended toolset including a sensor array for detecting a magnetic field or a non-intended toolset employing an analog type compass assembly instead of the sensor array, wherein a location of the fixed reference magnet in the implantable programmable bodily fluid drainage valve and size of the fixed reference magnet has substantially no negative influence on operation of the analog type compass assembly of the non-intended toolset when used to operate the implantable programmable bodily fluid drainage valve.
