Flexible electrode placement for improved EEG anesthesia monitoring

This technology describes methods that allow for greater flexibility of electrode placement in EEG “depth of anesthesia” monitoring systems.

Unmet Need: Adaptable method for EEG intraoperative monitoring

Monitoring the “depth of anesthesia” via an EEG machine during surgical procedures has been shown to improve patient cognitive function outcomes post-surgery. In the upcoming years, EEG monitoring during anesthesia may soon be a standard for all general anesthesia cases. Currently, the use of EEG monitoring is limited by the lack of flexibility in electrode configurations. The physician is limited to a small range of placement for the sensors due to their rigid plastic structure.

The Technology: Conversion of EEG current sensor into needle electrodes

This technology provides alternative methods to extend the range of EEG sensor placement, including lower profile sensors, more flexible wiring, and conversion of pad electrodes to needle electrodes. This will make it easier for physicians to place EEG sensors in the most optimal manner for a patient’s procedure. This technology can enhance anesthesia monitoring by increasing the flexibility for EEG sensor placement, and thus improve post-surgical outcomes, especially for elderly patients.

Applications:

  • “Depth of anesthesia” monitoring
  • Neurosurgical and ENT procedures
  • Research tool for neurological studies

Advantages:

  • Increases flexibility and versatility of electrode placement
  • Allows physicians to use optimal electrode placement locations
  • Can monitor multiple patients sequentially with only needle electrode replacement
  • Allows monitoring of elderly and specialized patient populations
  • Standardizes anesthesia monitoring for all surgeries
