Electrodes for Recording and Stimulation


inomed electrodes have been especially developed for intraoperative interventions. They are available as single use or autoclavable instruments. Don't hesitate to contact us if you don't find the instrument required in the selection below:

Subdermal Needle Electrodes

Subdermal Needle Electrodes (SDN) allow an easy and reliable recording of EMG signals. inomed offers different needles in various forms for multifacetted applications. Thus the corresponding nerve course can be monitored reliably during each operation. Electrodes are available as autoclavable product or as single use product for an increased safety.

Bipolar Vocalis Electrode

The bipolar vocalis electrode has been developed especially for thyroid surgery. The electrode can be placed transligamentar or transcartilaginar in situs in the vocalis muscle. This method is easy and safe to perform and delivers excellent EMG potentials.

Laryngeal Adhesive Electrode


An alternative method for monitoring the recurrent nerve is to use adhesive laryngeal electrodes, which are directly attached on the ventilation tube. The EMG activity of the vocal muscle can be monitored continuously without having to place an additional needle electrode. This very reliable method is already use by introduction of the tube into the patient. The electrode is directly stuck on an endotracheal tube placed at the vocal cord. The recording with inomed adhesive laryngeal electrode is a safe, reliable and scarcely invasive intraoperative monitoring method.

The laryngeal electrode with neutral adhesive electrode is available as single use product in two sizes:

  • for tubes of 6 – 7 mm inner diameter with an adhesive surface of: 32 mm length, 29 mm width
  • for tubes of 7,5 – 9 mm inner diameter with an adhesive surface of: 32 mm length, 37 mm width

Special Applicators for the Lower Cranial Nerves

inomed offers different special applicators for the recording of EMG signals of the lower cranial nerves. These applicators are used to place hooked wire electrodes or vocalis electrodes in the throat or in the vocalis muscle. A direct placement of electrodes in the target muscle allows the recording of excellent EMG signals.

Cork Screw Electrodes

These electrodes can be placed  on the head side according to the EEG 10-20 scheme. They offer a very reliable contacting and are colour-coded to simplify the placement. The electrodes are mainly used for transcranial stimulation but they can also be used for EEG and SEP signal recording.


D-Wave Catheter Electrode


FSR-03 stands for Flexible Stimulation and Recording Electrode, 3 pole. This special flexible 3-time electrode enables to record electric signals near the spinal cord (epidural) and to stimulate after connection to a stimulator.

This single use electrode is used for epidural recording of corticospinal signals or for epidural stimulation for intraoperative function control. The main application of the electrode is when the neuronal integrity of the spinal cord has to be recorded during interventions at the spinal channel.

Strip and Grid Electrodes


These electrodes are available with 4 to 64 contacts and are used together with the ISIS IOM System by following applications:

  • Localisation of dysfunctions with cortical EEG recording during pre-surgical diagnostic of certain pharmaco resisting epilepsies
  • direct stimulation on the cortex surface
  • neurophysiological mapping during neurosurgical interventions to localise the central sulcus with SEP recording (phase reversal)

Depth Electrodes, Guided Depth Electrodes with Mandrin

Depth electrodes are available with 5 to 18 contacts and guided depth electrodes with 4, 6 and 8 contacts. Both are used with the ISIS IOM System for following applications:

  • Localisation of dysfunctions with sEEG recording during pre-surgical diagnostic certain pharmaco resisting epilepsies
  • Direct intracerebral stimulation
