USER INTERFACE FOR EXTERNAL CHARGER FOR IMPLANTABLE MEDICAL DEVICE

摘要

User interface for external power source, recharger, for an implantable medical device (16). At least some of patient controls and display icons of an energy transfer unit (48) are common with at least some of the patient control and the display icons of a patient control unit (2). An energy transfer unit (48) is operable by the patient with less than three operative controls to control energy transfer from the external energy transfer unit (48) to the implantable medical device (16). An external antenna (52) having a primary coil (54) can inductively transfer energy to a secondary coil (34) of the implantable medical device (16) when the external antenna (52) is externally placed in proximity of the secondary coil (34). An energy transfer unit (48) has an external telemetry coil (46) allowing the energy transfer unit (48) to communicate with the implantable medical device (16) through the internal telemetry coil (44) in order to at least partially control the therapeutic output of the implantable medical device (16).
