Arc Zenith™ High‑Channel EEG & Direct Cortical Stimulation System

Arc Zenith™

288‑Channel Intracranial / Extracranial EEG with 1 MHz Sampling & Smart Zenect™ Connectors

Arc Zenith™ is Cadwell’s flagship epilepsy‑monitoring platform, built to handle the most demanding intracranial and extracranial studies. A modular 144‑ or 288‑channel amplifier samples at up to 1 MHz, records to its own onboard battery‑backed memory, and houses an integrated switch matrix for convenient direct cortical stimulation—no external boxes required. Rugged, water‑resistant construction and patented Zenect™ magnetic smart connectors streamline hook‑ups, reduce errors, and keep patients safe and comfortable throughout long‑term monitoring.

Key Features
  • Ultra‑High Channel Capacity & Speed: Up to 288 simultaneous channels capture every cortical contact in complex SEEG or grid studies. 1 MHz maximum sampling rate preserves high‑frequency oscillations and after‑discharge events critical for surgical planning.
  • Integrated Switch Matrix for Direct Stimulation: Built‑in electronic switch matrix lets clinicians program cortical‑stimulation parameters directly in Arc software—no patch panels or cabling changes.
  • Smart Zenect™ Magnetic Connectors: Auto‑identify each electrode in software, map inputs in one click, and select any input as ground or reference on every amplifier.
  • Onboard Battery & Data Capture: Internal power and solid‑state storage guard against data loss during patient transfers or power outages, ensuring uninterrupted, artifact‑free recording.
  • Rugged, Cleanable Design: Drop‑tested chassis with shock‑absorbing bumpers and water‑resistant housing stands up to busy EMUs and ORs.
  • Arc Software Ecosystem: Automated input mapping, single‑click “all‑electrode” montages, Synopsis™ trending, spike detection, and remote IP camera control—all from the same interface.

Why Choose Arc Zenith™?
  • : Capture every channel, every spike—288 CH at 1 MHz delivers uncompromised data for surgical localisation.
  • : One box for record and stimulate—integrated switch matrix eliminates external hardware and setup delays.
  • : Hook up faster, with fewer errors—Zenect connectors and automated mapping know exactly where every lead belongs.
  • : Rock‑solid reliability—onboard power, internal storage, and rugged housing protect your study from drops, spills, and outages.
  • : Scalable workflow—combine Zenith with Arc software to monitor multiple rooms remotely, automate trending, and generate rich reports in seconds.

Arc Zenith™ is engineered to simplify complex epilepsy‑monitoring workflows, minimise OR and EMU setup times, and deliver the ultra‑high‑fidelity EEG and stimulation capabilities today’s surgical teams demand.
