What DIXI medical does

DIXI medical is a privately held French medical device company founded in 1970 and headquartered in Marchaux-Chaudefontaine, France, specializing in the design, manufacture, and global distribution of precision intracerebral electrodes for stereo-electroencephalography (SEEG). The company serves neurosurgeons, neurologists, and epileptologists at specialized epilepsy surgery centers that perform procedures on patients with drug-resistant focal epilepsy. With products used in thousands of SEEG procedures annually across more than 40 countries, DIXI medical occupies a focused niche within the functional neurosurgery market. The company employs 51-100 people and operates from clean-room manufacturing facilities in eastern France.

The company's product portfolio centers on the MICRODEEP® family of multi-contact flexi-rigid depth electrodes, available in configurations ranging from 5 to 18 contacts with 0.8 mm diameter platinum/iridium construction. Recent innovations include the MICRODEEP® PIXEL high-resolution electrode for insular and thalamic targeting (15- and 18-contact versions), the MICRODEEP® Micro-Macro electrode for simultaneous population and single-unit neural recordings (CE mark pending), and the SEEG-Tx® proprietary thermocoagulation system with closed-loop automation (FDA 510(k) filed). Supporting the electrodes are IOM cortical electrodes for intraoperative neurophysiological monitoring and a complete range of stereotactic implantation tools, all CE-MDR certified and FDA approved. DIXI medical was the first SEEG electrode company to achieve EU MDR certification.

DIXI medical operates a hybrid go-to-market model. As of October 2025, the company shifted to exclusive direct sales in the United States, ending its distribution agreement with NeuroPace and building a US field team led by a new VP of Sales. Internationally, the company leverages regional distributors including Micromedical in Brazil and Varlix in Mexico, supplemented by direct engagement in select European markets. Revenue is generated primarily through one-time hardware sales of sterile single-use devices priced via quote, with customer relationships sustained through clinical training programs, SEEG education courses in partnership with societies such as ASEPA, and field-based clinical support. The customer base is concentrated among academic and tertiary epilepsy surgery centers, with notable reference accounts including Rush University Medical Center, UCHealth, UC Davis Health, Hospital Niño Jesús in Madrid, Hospices Civils de Lyon, and Hospital das Clínicas de Ribeirão Preto.

Revenue model

1. SEEG Electrodes and Medical Devices: DIXI medical generates revenue through the sale of precision intracerebral electrodes (MICRODEEP® family), cortical monitoring electrodes, implantation tools, and related surgical instruments. Products are sold as sterile single-use devices to epilepsy surgery centers globally. Revenue is primarily one-time purchase based on procedure volume, with recurring customer relationships driven by clinical preference and training investment.

Core offering

DIXI medical manufactures and sells precision intracerebral electrodes and accessories for stereo-electroencephalography (SEEG), used to localize epileptogenic zones in patients with drug-resistant epilepsy. Its portfolio includes the MICRODEEP® family of depth electrodes (standard, Micro-Macro, and PIXEL variants), IOM cortical electrodes, stereotactic implantation tools, and the SEEG-Tx® proprietary thermocoagulation system, all delivered as sterile single-use Class III medical devices to neurosurgery teams.

Product overview

DIXI medical offers a comprehensive portfolio of precision medical devices for stereo-electroencephalography (SEEG) in epilepsy care. The core product line centers on MICRODEEP® SEEG electrodes—including standard, Micro-Macro, and PIXEL variants—which are intracerebral depth electrodes for brain signal recording and thermocoagulation. Supporting products include IOM Cortical Electrodes for intraoperative monitoring, a complete range of Implantation Tools (drill bits, guiding screws, stylets), and the SEEG-Tx® proprietary thermocoagulation system. The company has pioneered in developing SEEG technology since the 1970s and holds both CE-MDR and FDA approvals for its electrode products, serving epilepsy centers in over 40 countries.

Recent moves8 records

Expansion highlights6 records

Emerging players

• NeuroPace: NeuroPace developed the RNS® responsive neurostimulation system for drug-resistant epilepsy and previously distributed DIXI medical's electrodes in the US. Its early termination of the DIXI distribution partnership reshaped DIXI's US go-to-market and positions NeuroPace as an adjacent player in the same epilepsy surgery workflow.
• Compumedics: Compumedics designs and manufactures EEG, sleep, and long-term monitoring systems used in epilepsy monitoring units. It is an emerging player in high-density EEG that overlaps with DIXI medical's downstream SEEG workflow and competes indirectly as non-invasive diagnostic tools improve.
• ClearPoint Neuro: ClearPoint Neuro provides MRI-guided neurosurgery navigation and drug delivery systems, intersecting with DIXI medical's robotic stereotactic workflow for SEEG electrode implantation. It is an emerging player in minimally invasive neurosurgery that targets overlapping epilepsy and movement-disorder neurosurgery centers.

Broad incumbents

• Medtronic: Medtronic's Cranial & Spinal Technologies division sells neurosurgical navigation, visualization, and ablation platforms (including Visualase laser ablation) that compete with DIXI medical's SEEG-Tx® thermocoagulation roadmap. Medtronic provided technical support for the first MICRODEEP® PIXEL implantation in Europe, illustrating its broad incumbent role in epilepsy surgery.
• Natus Medical: Natus Medical supplies neurology diagnostic and monitoring equipment (EEG systems, ICU monitoring) used alongside SEEG workflows in epilepsy monitoring units. While not a direct electrode competitor, it is a broad incumbent whose EEG platforms are commonly deployed alongside depth electrodes in DIXI medical's end-customer accounts.
• Integra LifeSciences: Integra LifeSciences owns Ad-Tech Medical (a direct SEEG electrode competitor) and supplies a broad portfolio of neurosurgery instruments and operating-room disposables. It competes with DIXI medical across epilepsy surgery centers via both branded depth electrodes and adjacent neurosurgery tools.

Direct peers

• Inomed Medizintechnik: Inomed makes stereotactic frames, neurostimulation equipment, and accessories used in SEEG/implantation workflows. Its frames (Susy, ZD) are explicitly integrated with DIXI medical's ACS-515C drill, making Inomed an adjacent supplier/partner and a relevant comparable in the neurosurgery workflow ecosystem.
• Ad-Tech Medical: Ad-Tech Medical manufactures intracranial and depth electrodes for SEEG and epilepsy surgery, making it the closest direct competitor to DIXI medical's MICRODEEP® product line. It is now part of Integra LifeSciences, giving the franchise additional commercial scale that DIXI medical competes against in the US and EU.
• PMT Corporation: PMT Corporation manufactures depth electrodes and neurosurgical instruments used in SEEG and intracranial monitoring, competing directly with DIXI medical for epilepsy surgery center share. Its product portfolio overlaps with MICRODEEP® electrodes and implantation accessories.

Others

• Brainlab: Brainlab provides surgical planning, navigation and intra-operative imaging software used during SEEG implantation and epilepsy surgery. It is an ecosystem enabler rather than a direct electrode competitor, but its platforms integrate with the robotic stereotactic workflows where DIXI medical's electrodes are implanted.
