Patent ID: 8630695

Claim:
A method for electronically locating a magnetic center of an implanted magnetic adjustable valve exhibiting a fluid flow reference axis (Ax) and a center furnished with a magnetic dipole ( 24 ), wherein said method comprises of the following steps: pinpointing the fluid flow reference axis (Ax) for flow of fluid through the valve ( 10 ), activating a mechanism for electronically detecting a magnetic field ( 36 , 74 , 82 ) at predetermined measurement positions (α 1 -α 12 ) angularly and uniformly distributed in a circle around an axis (X-X′), electronically measuring the magnetic field (CM) emitted by the valve at the predetermined measurement positions (α 1 -α 12 ), displacing the mechanism for electronically detecting a magnetic field until the magnetic field measured is substantially the same at substantially diametrically opposite positions, the magnetic center of the valve being in the center between said opposite positions.
