    • A spinal cord stimulation (SCS) system includes multiple electrodes, multiple, independently programmable, stimulation channels within an implantable pulse generator (IPG) which channels can provide concurrent, but unique stimulation fields, permitting virtual electrodes to be realized. The SCS system includes a replenishable power source (e.g., rechargeable battery), that may be recharged using transcutaneous power transmissions between antenna coil pairs. An external charger unit, having its own rechargeable battery can be used to charge the IPG replenishable power source. A real-time clock can provide an auto-run schedule for daily stimulation. An included bi-directional telemetry link in the system informs the patient or clinician the status of the system, including the state of charge of the IPG battery. Other processing circuitry in the IPG allows electrode impedance measurements to be made. Further circuitry in the external battery charger can provide alignment detection for the coil pairs.
    • 脊髓刺激(SCS)系统包括在可植入脉冲发生器(IPG)内的多个电极,多个独立可编程的刺激通道,其通道可以提供同时但独特的刺激场,允许实现虚拟电极。 SCS系统包括可补充电源(例如,可充电电池),其可以使用天线线圈对之间的经皮功率传输进行再充电。 可以使用具有自己的可充电电池的外部充电器单元为IPG可补充电源充电。 实时时钟可以提供每日刺激的自动运行时间表。 系统中包括的双向遥测连接通知患者或临床医生系统的状态,包括IPG电池的充电状态。 IPG中的其他处理电路允许进行电极阻抗测量。 外部电池充电器中的进一步电路可以为线圈对提供对准检测。
