About this trial

The objective of this prospective interventional monocentric clinical investigation is to evaluate the feasibility and performance of the flexible high-density SOFT ECoG electrode grids, manufactured by Neurosoft Bioelectronics SA (test device; TD), in comparison to regular high-density electrode grids (ADTech, CE-marked) (control device; CD) routinely used at the investigation site during epilepsy surgery.

Subjects will undergo ≥ 2 additional intracranial recordings pre- and post-resection with the TD next to the standard recordings with the CD during ECoG-tailored epilepsy surgery.

Eligibility criteria

Qualifiers

Age ≥18 years at the time of enrolment

Lesional epilepsy (incl. secondary mesial temporal sclerosis) that is considered a candidate for intra-operative high-density grid recordings (incl. patients who underwent sEEG preceding resective surgery)

Provided informed consent for study participation by the subject

Disqualifiers

Occipital lesion

Surgeries involving a primary mesial temporal lesion, a disconnection, or hemispherectomy.

Planned ioECoG recordings during fully awake surgery and/or functional recordings

Use of anticoagulants that cannot be discontinued during the perioperative period, or a factor XIII deficiency or any other haematological disease
