In another embodiment, the PDCs are driven by an AC power source at a frequency different from that of the charging coil. By comparing the relative reflected magnetic field strengths at each of the PDCs, 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.Type: GrantFiled: September 11, 2013Date of Patent: June 2, 2015Assignee: Boston Scientific Neuromodulation CorporationInventor: Daniel Aghassian
