## Indications for Use

The EAD is an electro acupuncture device for use in the practice of acupuncture by qualified practitioners of acupuncture as determined by the states.

## Device Story

Battery-operated, single-use electro-acupuncture device; provides auricular point nerve stimulation for pain therapy. Input: preprogrammed electrical pulse parameters. Transformation: microprocessor-controlled generation of low-frequency electrical pulses transmitted via stainless steel wires to needle arrays (titanium needles) placed behind the ear. Output: periodic electrical stimulation (2 hours on/2 hours rest) for up to 120 hours. Used in clinics or at home; applied by qualified acupuncture practitioners. Output informs pain management therapy; provides continuous stimulation over several days to potentially benefit patients with acute or chronic pain.

## Clinical Evidence

Bench testing only. No clinical data provided. Testing included biocompatibility (cytotoxicity, sensitization, irritation per ISO 10993), electrical safety (IEC 60601-1, IEC 60601-2-10), EMC (IEC 60601-1-2), and software verification/validation.

## Technological Characteristics

Battery-powered (3V CR1220 Lithium) electro-acupuncture stimulator. Output: max 3.2V, 1-10Hz modulating frequency, 1ms pulse width, bipolar. Dimensions: 36x16x7mm; weight 4g. Needles: 0.5mm width x 2mm length. Materials: stainless steel wires, titanium needles. Connectivity: standalone. Sterilization: VDMAX25 method (ISO 11137-2). Software: microprocessor-controlled, minor level of concern.

Dear Ms. Colleen Hittle:

We have reviewed your 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

# Non-Clinical Performance Data

## Biocompatibility Testing

The biocompatibility evaluation for the adhesive for the EAD device was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, " May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests:

- . Cytotoxicity
- Sensitization
- Irritation

The EAD adhesive is considered tissue contacting for a duration of less than 30 days. The other patient contacting materials contained in the subject device are unchanged from the P-Stim predicate device.

### Electrical Safety and Electromagnetic Compatibility (EMC)

Electrical safety and EMC testing were conducted on the EAD device. The system complies with the IEC 60601-1 and IEC 60601-2-10 standards for safety and the IEC 60601-1-2 standard for EMC.

### Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "minor" level of concern, since a failure or latent flaw in the software could not directly result in serious injury or death to the patient or operator.

### Sterility/Shelf Life

Sterilization Validation was conducted on the EAD device needles and wiring harness using the VDMAX25 method according to ISO 11137-2 and ISO 11737-2. Performance and stability of the EAD packaging was validated in accordance with ISO 11607-1 and Accelerated aging of the EAD was performed in accordance with ASTM F1980-07. Packaging qualifications are according to ISO 11607-1 and machine qualifications for the sealing process are according to ISO 11607-2.

# Conclusion

The non-clinical data support the safety of the device and the hardware and software verification and validation demonstrate that the EAD device should perform as well as the predicate device in the specified use conditions.
