The D-Wave Catherer Electrode is used to stimulate the spinal cord. The flexible stimulation and recording electrode, 3 pole provides the record of the electric signals near the spinal cord and provide stimulation through a stimulator. During the point of intervention of the spinal channel with the neuronal integrity of the spinal cord the recordings are carried out by the device. The electrode is intended for a single use for recording the epidural corticospinal signals based on which epidural stimulation is provided for intraoperative function control.
