Intended Use
Aluna 2 is intended for monitoring FEV1 (Forced exhalation in the first second) and PEF (Peak Expired Flow Rate) for home use. The device is designed for pediatric to adult users. Aluna is not recommended for children under 5 years of age. Additionally, the device may be used by clinicians for in-office monitoring.
Device Description
Aluna 2 consists of three main components: - A small hand-held peak flow meter that captures differential pressure, converts it to digital data points, and transmits the data to a mobile device via Bluetooth. - A mobile application that collects and transmits the differential pressure readings from the spirometry device and processes it to estimate the exhaled air flow rate and volume. - An Application Programming Interface (API) to facilitate communication with a cloud server used for data storage.
More Information

Not Found

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the device description focuses on standard signal processing and data transmission.

No
The device is intended for monitoring FEV1 and PEF, which are diagnostic measurements, not therapeutic actions.

Yes
The device is intended for monitoring FEV1 and PEF, which are diagnostic indicators for respiratory health. It is used in both home and clinical settings for monitoring, implying its role in assessing a medical condition.

No

The device description explicitly states that Aluna 2 consists of a "small hand-held peak flow meter" which is a hardware component.

Based on the provided information, the Aluna 2 device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs are used to examine specimens derived from the human body. The description of Aluna 2 clearly states it measures FEV1 and PEF by capturing differential pressure from exhaled air. This is a measurement of a physiological function (lung capacity and airflow), not an analysis of a biological specimen like blood, urine, or tissue.
  • The intended use is for monitoring lung function. The intended use is focused on monitoring respiratory parameters (FEV1 and PEF) for home and clinical use. This aligns with the function of a spirometer or peak flow meter, which are generally considered medical devices, but not IVDs.

Therefore, based on the provided text, Aluna 2 falls under the category of a medical device that measures physiological parameters, not an In Vitro Diagnostic device.

Dear Carol Vierling:

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 (the 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 available 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

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 of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
