Abstract: A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.

Abstract: An apparatus, system, and method for neurostimulation by high frequency ultrasound. In one embodiment, an apparatus includes a pulse generator, an ultrasound transducer coupled to the pulse generator, and an implantable stimulator. The implantable stimulator may include a piezoelectric element configured to convert ultrasound signals from the ultrasound transducer into electrical signals, a rectifier configured to convert alternating current from the piezoelectric element to a monophasic current, a capacitor coupled to the rectifier, and a first electrode and a second electrode coupled to the rectifier and capacitor and configured to transmit the monophasic current to body tissue. In addition, the apparatus may include a current-limiting circuit configured to limit the amount of current transmitted to the body tissue.

Abstract translation: 用于提供神经刺激的系统包括外部装置（“外部激励器”）和植入装置。 外部激励器包括对植入装置进行感应供电的能量源。 这种外部激励器的实例包括具有以下至少一种的装置：超声换能器，射频（RF）发射器和太阳能电池。 植入装置包括将其最大能量输出限制到预定饱和阈值的电路，使得来自外部激励器的过量刺激不会使植入装置的输出超过饱和阈值。 然后对外部激励器的输出信号进行脉冲宽度调制，以从植入装置产生期望量的输出刺激，以刺激生物电可兴奋的组织达到期望的水平。
