System and method for treating a nerve symptom
An implantable electrical stimulation system for treating a nerve symptom, the system comprising an implantable device. The implantable devices includes a wave generator that is operable to generate a signal wave and a white noise, mix the signal wave and the white noise, and produce an electrical stimulating signal. The system further comprises an electrode unit located in close proximity to a target nerve and is operable to provide the electrical stimulating signal to the nerve. The system further comprises an external controlling device.
1. An implantable electrical stimulation system for treating a nerve symptom, the system comprising:
an implantable device comprising:
a wave generator, wherein the wave generator is operable to generate a signal wave and a white noise, mix the signal wave and the white noise, and produce an electrical stimulating signal;
an electrode unit adapted to be located in proximity to a target nerve for providing the electrical stimulating signal to the nerve; and
an external controlling device;
wherein the electrode unit comprises more than one electrode separated by insulating parts, and a distance between the electrode unit and the target nerve is between about 2 mm and about 6 mm.
2. The system of claim 1 , wherein the system generates radiofrequency stimulation pulses.
