Abstract
A sensing probe assembly and method for locating a magnetic field emitted by an implanted medical device. The assembly has a housing containing a magnetic field sensor circuit having an indicator light and a magnetic switch. The assembly further has a structure for marking the location of the magnetic field. The method utilizes a marking system whereby at least four points forming at least two perpendicularly intersecting line segments are located and marked above the magnetic field. The intersection is then used as a reference point for performing a medical procedure on the implanted medical device.
