Abstract
Techniques associated with a universal recharging device for recharging a power source of implantable medical devices (IMDs). The recharging device includes an interface to allow an antenna assembly to be removably coupled. The antenna assembly has a primary coil and a corresponding sense coil. The sense coil has a configuration that is selected based on the configuration of the primary coil. The sense coil is adapted to prevent voltage across the primary coil from exceeding a maximum voltage amplitude allowable with the recharging device. The maximum voltage amplitude may be selected based on a maximum magnetic field strength to which a patient is to be exposed. In one embodiment, the maximum voltage amplitude is programmable.
