Reason for Recall: There is a concern the microelectrodes are defective and may cause injury to the brain. As a result, there is the potential for scraping (abrasion) of brain tissue and for broken pieces to remain in the brain tissue when the physician removes the electrode. This may lead to hemorrhaging or a seizure, as well as death.
