Abstract
The present invention changes the magnet-mode of an active implantable medical device (AIMD) using a static strip magnet comprising at least a first, second and third magnet. 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, or placed in a programmed mode.
