    • Techniques are described for generating electrical stimulation current pulses for delivery of electrical stimulation therapy via a current-controlled system that emulates voltage pulses generated via a voltage-controlled system. In one example, a method includes receiving user input specifying a voltage level of electrical stimulation to be delivered by one or more of a plurality of electrodes implanted within the patient, selectively coupling the one or more electrodes to respective regulated current paths to deliver the electrical stimulation to the patient, selectively coupling at least another of the plurality of electrodes implanted within the patient to an unregulated current path to deliver the electrical stimulation to the patient, determining a regulated current for each respective regulated current path in order to produce the specified voltage level at the one or more electrodes selectively coupled to the respective regulated current paths, and delivering the determined regulated currents via the respective regulated current paths.
    • 描述了用于产生用于通过电流控制系统递送电刺激治疗的电刺激电流脉冲的技术,该电流控制系统模拟经由电压控制系统产生的电压脉冲。 在一个示例中,一种方法包括接收用户输入,其指定要由植入在患者体内的多个电极中的一个或多个电极递送的电刺激的电压电平,选择性地将一个或多个电极耦合到相应的调节电流路径以递送电 对患者的刺激,选择性地将植入患者体内的多个电极中的至少另一个电极耦合到未调节的电流路径以将电刺激传递给患者,为每个相应的调节电流路径确定调节电流,以便产生指定的电压 所述一个或多个电极选择性地耦合到相应的调节电流路径,并且经由相应的调节电流路径传送所确定的调节电流。

    • Medical device recharging systems include a controller and a separate recharge device that communicate wirelessly together to provide recharging to an implantable medical device. Either the controller or the recharge device may also communicate wirelessly with the implantable medical device to obtain recharge status and other information. There may be multiple recharge devices present within communication range of the controller, and the controller may determine which recharge device to activate depending upon proximity of each recharge device to the implantable medical device. The controller may allow the recharge device that is active at any given time to change so that the patient having the implantable medical device can move about in the area where the recharge devices are located while recharging continues.
    • 医疗装置再充电系统包括一个控制器和一个单独的再充电装置,它们以无线方式通信在一起以向可植入医疗装置提供再充电。 控制器或充电设备也可以与可植入医疗设备进行无线通信,以获得充电状态和其他信息。 在控制器的通信范围内可能存在多个充电设备,并且控制器可以根据每个再充电设备与可植入医疗设备的接近度来确定要激活的再充电设备。 控制器可以允许在任何给定时间处于活动状态的再充电设备改变,使得具有可植入医疗设备的患者可以在充电设备所在的区域中移动,同时继续充电。
