摘要： A passive implantable relay module includes a first coupler arm configured to wirelessly receive electromagnetic energy radiated through electric radiative coupling from a transmitting antenna located outside a subject's body; a second coupler arm; and a connector portion comprising a first metal core and a first dielectric coating surrounding the first metal core, the connector portion configured to connect the first coupler arm to the second coupler arm such that when the passive implantable relay module is implanted inside the subject's body and the transmitting antenna initiates wireless energy transfer to the first coupler arm via non-inductive coupling, electromagnetic waves carrying the electromagnetic energy received at the first coupler arm propagate along the first metal core to arrive at the second coupler arm, where the electromagnetic energy arriving is wirelessly transferred, again via non-inductive coupling, to a receiving antenna on a passive wireless neural stimulator device.

摘要： A system includes a controller module, which includes a storage device, a controller, a modulator, and one or more antennas. The storage device is stored with parameters defining a stimulation waveform. The controller is configured to generate, based on the stored parameters, an output signal that includes the stimulation waveform, wherein the output signal additionally includes polarity assignments for electrodes in an implantable, passive stimulation device. The modulator modulates a stimulus carrier signal with the output signal to generate a transmission signal. The one or more antennas transmit the transmission signal to the implantable, passive stimulation device such that the implantable, passive stimulation device uses energy in the transmission signal for operation, sets the polarities for the electrodes in the implantable, passive stimulation device based on the encoded polarity assignments, generates electrical pulses using the stimulation waveform, and applies the electrical pulses to excitable tissue.
