Neurostimulator implantable NeуSi-3M

  • Neurostimulator «NeуSi-3M» is used in neurosurgery and is designed for long-term electrical stimulation of the posterior pillars of the spinal cord, areas of the brain, peripheral nerves and plexus in order to remove pain syndromes of various origins, and also to restore the functional state of damaged peripheral nerves and plexus, the possible return of sensitivity and the restoration of some functions of the affected organs.


  • The stimulating electrical signal is transmitted to the electrodes of the receiving antenna implanted in the patient’s body, from the generator, using the transmitting antenna, on the radio channel.
  • Neurostimulator «NeуSi-3M» — two-channel and has five modes of stimulation:

— fixed frequency on the first channel;

— fixed frequency on the second channel;

— modulation of frequency on the first channel;

— modulation of frequency on the second channel;

— modulation of frequencies by both channels.

  • The stimulation mode is selected or changed by repeatedly sequentially pressing the Mode button. The patient has the ability to choose a stimulation regimen and adjust the amplitude of pulses. All other parameters of stimulation are set or changed by the attending physician.
  • The duration of the electrostimulation session is prescribed by the attending physician.
  • The NeуSi-3M neurostimulator is powered by a battery located in the Generator Block.
