    A novel brain recording electrode minimizes tissue damage with a hollow-core design and stylet guidance. Its flexible, helical structure moves with the brain, preventing injury, and has shown promising clinical results in epilepsy patients.

    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Medical Devices

    Background:

    • Brain recording requires precise electrode placement to minimize tissue damage.
    • Existing macroelectrodes can cause significant trauma during insertion and movement.
    • The need for flexible, durable electrodes that move with neural tissue is critical for long-term brain monitoring.

    Purpose of the Study:

    • To describe a novel multicontact macroelectrode for brain recordings.
    • To highlight the design features that reduce tissue trauma and improve durability.
    • To present initial clinical findings in epileptic patients.

    Main Methods:

    • Development of a hollow-core macroelectrode with recessed contacts.
    • Integration of a central stylet for guided insertion.
