Device Story

PE-210AK Switch Box is an accessory for the EEG-1200A system; enables switching of cortical electrodes between EEG recording and external cortical stimulation. Hardware consists of electronic switches in an enclosure; controlled by software installed on the EEG's PC. User selects stimulation sites via GUI on brain map images (JPEG/BMP/TIF); system highlights selected electrodes (Red/Blue). Software manages stimulation parameters (intensity, duration, trigger signals); registers stimulation events; generates functional mapping reports. Used in hospitals/clinics by medical professionals for epilepsy diagnostics and surgical planning. Output includes visual mapping, event tables, and reports for clinical review. Benefits include streamlined workflow for functional brain mapping and integrated documentation of stimulation events.

Clinical Evidence

No clinical data. Bench testing only, including electromagnetic, environmental, safety, and performance testing, along with design validation to confirm software and hardware operation against specifications.

Technological Characteristics

Electronic switch box; connects to multi-channel electrode junction boxes (JE-0011/0012/0013). Controlled by software on an off-the-shelf PC. Provides trigger output for external stimulators. Non-sterile; no patient-contacting materials. Operates via Windows-based GUI. Network-capable for file transfer.

Indications for Use

Indicated for use in hospital or medical facilities under professional supervision for patients of any age requiring EEG recording, sleep studies, or functional brain mapping to support diagnostic and surgical epilepsy procedures.

Regulatory Classification

Identification

#### A summary of the technological characteristics of the device compared to the . predicate device:

{2}------------------------------------------------

The new PE-210AK Switch Box is connected between the multi-channel electrode junction box (JE-0011/0012/0013 and switches the connection destination of signal lines of electrodes between the electroencephalograph and the external stimulation unit (only one pair of electrodes can be switch at a time). The switch box is controlled by the switch box software which is installed on the electroencephalograph (EEG). Both the EMU128s and the PE-210AK have a hardware switch box and software controls that allow electrodes to be switched between the stimulation unit and the EEG device.
