Device to control magnetic rotor of a programmable hydrocephalus valve
First Claim
1. A setting adjustment tool for a magnetically adjustable device implanted in a patient, the magnetically adjustable device including a housing with a rotor having an axis of rotation and at least one rotor magnet, the rotor having a range of arcuate motion within each of a plurality of selectable performance settings, and wherein the rotor has an axle which turns about the axis of rotation, the setting adjustment tool comprising:
- a circumference;
a plurality of magnetic coils, each coil circumferentially distributed a predetermined angular distance on the circumference of the setting adjustment tool;
wherein each magnetic coil is operable to activate and attract or repulse the at least one rotor magnet;
wherein a first coil of the plurality of magnetic coils is activatable for causing the at least one rotor magnet to move the rotor away from the first coil;
wherein a second coil of the plurality of magnetic coils is activatable for causing the at least one rotor magnet to move the rotor next to the second coil;
wherein a third coil of the plurality of magnetic coils is activatable for causing the at least one rotor magnet to move the rotor to a pocket of the magnetically adjustable device between second and third coils.

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.
