20 Claims

1. An active implantable medical device (AIMD) system, comprising:

a) an AIMD that is configured to deliver electrical stimulation therapy to body tissue and/or sense electrical biological signals from body tissue, wherein the AIMD comprises a housing containing a magnetic field-detection sensor connected to electronic circuits;

b) a static strip magnet comprising:

i) a first static magnet of at least a first defined Gauss and of a north or south polarity;

ii) a second static magnet connected to the first static magnet, wherein the second static magnet is of at least a second defined Gauss and of a north or south polarity that is opposite the polarity of the first static magnet; and

iii) a third static magnet connected to the second static magnet, wherein the third static magnet is of at least a third defined Gauss and of a north or south polarity that is the same polarity as that of the first static magnet,

c) wherein the electronic circuits of the AIMD have been programmed to register when the static strip magnet has been swiped across the AIMD so that when the magnetic field-detection sensor detects a defined north and south polarity sequence of the first, second and third magnets, the electronic circuits have been programmed to enter into magnet-mode with electrical stimulation therapy of the body tissue and/or electrical sensing of biological signals from the body tissue being suspended, maintained in a preset mode, and/or placed in a programmed mode.
