MICRODEEP® SEEG Electrodes

Dixi depth electrodes (Microdeep®) are thin, multi-contact wires implanted into the brain for Stereo Electro Encephalography (SEEG). They help diagnose drug-resistant epilepsy by recording and stimulating brain activity to precisely locate seizure origins. They can also be used for radiofrequency ablation to treat the seizures.

Features:-

• This is their primary line of depth electrodes for SEEG
• Used to accurately locate and map epileptic foci (the areas of the brain where seizures originate)
• Helps in identifying eloquent brain areas (those responsible for critical functions like language or movement) to avoid damaging them during surgery
• They feature multiple contacts along their length to record electrical activity from various brain regions
• Available with a range of contacts, typically from 5 to 18 contacts
• Each electrode is for single patient use and delivered sterile
• Designed to prevent electrode movement, ensure a good seal, and serve as a depth marker

MICRODEEP® Micro-Macro Depth Electrodes

The DIXI Medical MICRODEEP® micro-macro depth electrodes are sophisticated medical tools designed for neurosurgery, specifically for Stereo-electroencephalography (SEEG) procedures. These electrodes are crucial for accurately locating the source of seizures in patients with drug-resistant epilepsy. Characterized by their small diameter and flexi-rigid structure, they feature both macro-contacts and deployable micro-contacts (tetrodes) at their distal end. This unique design enables clinicians to record both broad and highly detailed, single-unit brain activity, providing invaluable data for pre-surgical evaluation and functional mapping of epileptic foci. These consumables are intended for clinical research use only.

Features:-

• Diameter: 0.8 mm
• Platinum / Iridium macro-contacts – 2 mm length
• Micro-contacts: Tetrodes made of Tungsten (~20 µm wire)
• Tetrode diameter: 70 microns
• Micro-contacts deploy up to 2 mm in length between macro-contacts 1 & 2
• Two electrode output connectors:
  • 1 connector for macro-contact (green connector)
  • 1 connector for micro-contact (yellow connector)
• 9 macro-contacts / 2 tetrodes (8 micro-contacts)
• Active exploration length: 33.2 to 50.8 mm
• Compatible with existing MICRODEEP® SEEG surgical workflow and tools
