System for an implantable medical device having an external charger coupleable to accessory charging coils

摘要

An external charger system is disclosed comprising an external charger with an internal charging coil, as well as an output port coupleable to one of a plurality of types of external accessory charging coils of varying shapes and sizes. If the internal charging coil of the external charger is sufficient for a given patient's charging needs, the accessory charging coils may be detached from the external charger, and the external charger may serve as a standalone self-contained external charger. The external charger can automatically detect which of the plurality of types of accessory charging coils is connected, and can adjust its operation accordingly. This versatile design allows the external charger system to be used by large numbers of patients, even if their particular implant charging scenarios are different.
