External controller for an implantable medical device system having an external charging coil powered by an external battery

摘要

An external controller / charger device having a “graphical user interface (GUI)” and a first battery, and an external charge that can be coupled to the external controller / charger device and includes or is associated with a second battery An integrated external controller / charger system for an implantable medical device including a coil assembly is disclosed. The second battery is used to excite the charging coil in the external charging coil assembly, while the first battery powers other aspects of the system (data telemetry circuit, control circuit, GUI, etc.). Used for. Since the second battery powers a relatively high power charging function, the first battery in the external controller / charger device can be miniaturized. In addition, the second battery provides that a suitable external controller device (eg, a mobile device such as a mobile phone) provides a charging function even if the first battery is otherwise inappropriate. enable.
