  "textContent": "An implantable neurostimulator that communicates with an extracorporeal energy controller through radio frequency and receives electrical energy, including: a main control chip that includes a main control CPU, a main memory, and a digital to analog conversion current source circuit; a stimulator antenna and its impedance matching circuit, which are radio-frequency coupled with the extracorporeal energy controller; a rectification energy storage circuit that extracts electrical energy from the received input signal and stores electrical energy; a modulation/demodulation circuit that extracts control information including clinical stimulation parameters from the received input signal; an electrode interface; one or more stimulation electrodes, with the electrode interface allocating stimulation pulse sequences to each corresponding stimulation electrode; wherein the main memory stores the received control information, the digital to analog conversion current source circuit generates the stimulation pulse sequences based on the clinical stimulation parameters, and the main control CPU controls operation of the implantable neurostimulator. The implantable neurostimulator of the present invention can avoid treatment failure caused by interruption or obstruction of radio frequency communication.",
