Device Story

Neurodyn V2.0 and Aussie V2.0 are multi-channel transcutaneous neuromuscular stimulators. Devices deliver various electrical currents (Aussie, Russian, FES, TENS, Interferential, Microcurrent, DC, High Voltage) to patients via electrodes. Operated by clinicians in hospitals or clinics. Device transforms electrical energy into therapeutic pulses; intensity is adjusted based on patient sensation. Output provides muscle stimulation, pain relief, or re-education. Clinicians use device to manage pain, prevent atrophy, or improve gait. Benefits include non-invasive pain management and physical rehabilitation support.

Clinical Evidence

Bench testing only. Compliance with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-10 standards demonstrated.

Technological Characteristics

Powered muscle stimulator; 4-channel output; ABS plastic housing; LCD display. Energy source: 100-240VAC, 50/60Hz. Modalities: Aussie, Russian, FES, TENS, Interferential, Microcurrent, DC, High Voltage. Safety: Double isolation, keyboard lock, auto-shutoff. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-10. Biocompatibility: FDA-cleared electrodes.

Indications for Use

Indicated for patients >=12 years old and >=35 kg requiring muscle stimulation, pain relief, or muscle re-education. Modalities include FES, TENS, Interferential, Premodulated, Russian, Aussie, Microcurrent, DC/Polarized, and High Voltage Pulsed current. Used for chronic intractable pain, acute post-traumatic/post-surgical pain, muscle spasms, disuse atrophy, and gait improvement in partially paralyzed patients.

Regulatory Classification

Identification

Dear Rodrigo Abreu:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies.combination product submissions. 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

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4.
