Abstract
A setting adjustment tool for a magnetically adjustable device implanted in a patient includes a circumference. A plurality of magnetic coils can be circumferentially distributed on a circumference of the tool. One of the magnetic coils can be movable along the circumference between a plurality of predetermined positions associated with the selectable performance settings. The magnetic coils may also be capable of attracting or repulsing the at least one magnet of the rotor of the implanted device in a radial direction by at least a predetermined angle within a plane of rotation of an at least one magnet of the rotor thereby inducing a rotating moment into the rotor.
