Indications for Use

EIS-GS (Electro Interstitial Scan-GS) is a medical device for the measurement of galvanic skin response. The device is not intended for use in any diagnosis. The data are stored in PC in the Backup system of the EIS-GS software. The device is intended for use on healthy adult subjects. The device is intended use in practitioner's office and clinical setting. Prescription Use Caution: Federal law restricts this device to sale by or on the order of a physician.

Device Story

EIS-GS is a programmable electro-medical system for measuring galvanic skin response. It consists of a USB-connected hardware box, six electrodes (disposable forehead, reusable hand/foot plates), and PC-based software. Operation involves sending a weak current (1.28V, 700Hz, 12µA) through 22 body pathways via tactile electrodes. The system records electrical conductivity changes over 120 seconds. Used in clinical settings by practitioners, the device transmits data via USB to a PC for storage. It provides skin conductance measurements on the PC screen. It is not diagnostic; it serves as a measurement tool for healthy adults. Benefits include non-invasive monitoring of skin conductance. The device requires the patient to remain seated during the 120-second acquisition period.

Clinical Evidence

Bench testing only. No clinical data provided. Evidence consists of hardware calibration tests using a simulator, software verification (SRS/SDS/STD/STR), and electrical safety/EMC testing in compliance with IEC 60601-1-1 and IEC 60601-1-2.

Technological Characteristics

Hardware: USB-powered (5V), 1.28V/12µA/700Hz output. Electrodes: Ag/AgCl disposable forehead electrodes (1.575 cm2) and AISI 304 stainless steel reusable hand/foot plates. Galvanic isolation via TRACO DC/DC 4KV optocouplers. Connectivity: USB 2.0. Software: PC-based, Windows 7. Classification: Class II, BF protection. Sterilization: Not applicable (reusable/disposable components).

Indications for Use

Indicated for measurement of galvanic skin response in healthy adult subjects. Intended for use in practitioner offices and clinical settings. Contraindicated for patients with dermatological lesions, excessive perspiration, implanted electronic devices (e.g., pacemakers, defibrillators), metal pins/prostheses in extremities/joints, pregnancy, or absence of limbs. Not for use in patients unable to sit still.

Regulatory Classification

Dear Dr. Clement:

We have reviewed vour Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
