title: Multipolar hollow-core electrode for brain recordings.
abstract: A multicontact macroelectrode for brain recordings is described. Its hollow-core structure and slightly recessed contacts allow the electrode to be guided with a central stylet for minimal tissue trauma. The helical design of the electrode is characterized by high fatigue resistance and high flexibility allowing movement with the brain and preventing slicing through tissue. Clinical results have been obtained on epileptic patients.
