Brief Summary:
The WIN Study is a prospective, interventional, multi-center, open-label premarket study designed to confirm the safety, performance and intended use of the WISE Cortical Strip (WCS) for CE certification purposes. Participants with documented diagnosis of epilepsy or brain tumor requiring intracranial surgery, who meet all eligibility criteria, will undergo IntraOperative Neurophysiological Monitoring (IONM) during a neurosurgical intervention with the WCS and a comparator device.

Condition or disease Intervention/treatment Phase
Brain Tumor Adult Epilepsy Device: WISE Cortical Strip Not Applicable

Detailed Description:

The IONM is the use of electrophysiological methods to identify important neural structures in the operative field, including eloquent areas, in order to monitor their functional integrity during the neurosurgical lesion resection. The benefit of performing functional monitoring of the areas surrounding the lesion is to minimize neurological damages during surgical lesions resection and thus to avoid and/or limit significant post-operative impairments. During the therapeutic resection of brain tumors or epileptogenic lesions, the use of the IONM is associated to other intraoperative techniques (e.g. brain mapping techniques) that, together to combined efforts of a multidisciplinary team of neurosurgeons, neuroradiologists, neuropsychologists, and neurophysiologists, contribute to the definition of location, extension, and extent of functional involvement that a lesion causes in an individual participant.

The principal electrophysiological methods to perform the IONM are the recording of brain's electrical activities (Somatosensory Evoked Potentials, SEPs and ElectroCorticoGraphy, ECoG) and electrical stimulation of motor regions (to elicit Motor Evoked Potentials, MEPs) using cortical strips placed on surface of the brain.

Thus, the WCS is intended to be used intraoperatively on the brain surface, to perform brain monitoring.

Secondary Outcome Measures :
  1. Impedance values measured for the WISE Cortical Strip. [ Time Frame: During the surgery ]
  2. Motor Evoked Potentials (MEPs). [ Time Frame: During the surgery ]
  3. Dedicated usability questionnaire. [ Time Frame: Following surgeries ]
