Electrical energy is transcutaneously transmitted from an external charger to an implanted medical device. The external charger includes a charging head comprising a plurality of pivotable hinged sections for selectively shaping the charging head to conform to a surface of a patient. The external charger further includes an alternating current (AC) charging coil housed in the charging head for transcutaneously transmitting electrical energy to the implanted medical device. The charging head may also include one or more sensors for determining the shape of a charging coil in the charging head, which cause the charge of the coil to be adjusted based on the coil shape. |
