AN IMPROVED EXTERNAL CHARGER FOR A MEDICAL IMPLANTABLE DEVICE USING FIELD SENSING COILS TO IMPROVE COUPLING
摘要
By incorporating magnetic field sensing coils in an external charger, it is possible to determine the position of an implantable device by sensing the reflected magnetic field from the implant. In one embodiment, two or more field sensing coils are arranged to sense the reflected magnetic field. By comparing the relative reflected magnetic field strengths of the sensing coils, the position of the implant relative to the external charger can be determined. Audio and/or visual feedback can then be communicated to the patient to allow the patient to improve the alignment of the charger.
