Intended Use
The AdheResp Smart Breath-actuated Mesh Nebulizer is a system to aerosolize liquid medications for inhalation for patients ranging from pediatrics equal to or greater than 5 years old to adults who can coordinate breathing. The environment of use are Hospital/institutional settings, home care use, schools, and long-term care facilities.
Device Description
The AdheResp Smart Breath-actuated Mesh Nebulizer consists of a main unit, medication reservoir, mouthpiece, key tag and charging cable, or power adapter. The medication reservoir could be further separated into a medication container and an aerosol chamber. Principle of Operation: There are two key features in the AdheResp Smart Breath-actuated Mesh Nebulizer, which are vibrating mesh nebulization and breath-actuation functions. The AdheResp Smart Breath-actuated Mesh Nebulizer is an active mesh nebulizer. Active mesh nebulizers operate by electrically activating a piezoelectric (PZT) ceramic element that rapidly contracts and expands when applied a voltage to it. The vibrations of the PZT are transmitted to the mesh membrane, which is in contact with the liquid medication loaded in the medication container. This vibration pushes the liquid or suspension through the fine conical holes of the mesh, forming aerosol droplets for the user to inhale.
More Information

No.
The document describes a mechanical device for aerosolizing medication and does not mention any AI, DNN, or ML components.

Yes.
The device is used to aerosolize liquid medications for inhalation which is a therapeutic intervention.

No

This device is a nebulizer designed to deliver medication as an aerosol, not to diagnose a medical condition. Its function is therapeutic, not diagnostic.

No

The device is a physical medical device (nebulizer) with hardware components like a main unit, medication reservoir, mouthpiece, and a piezoelectric element. Its primary function is to aerosolize liquid medications, which is a mechanical/physical process, not a software-driven one. While it may incorporate some software for control or user interface, it is fundamentally a hardware device.

No.
An IVD is used to examine specimens derived from the human body to provide information for diagnostic, prognostic, or treatment purposes. This device is a nebulizer for drug delivery, not for diagnostic testing of biological specimens.

Dear Paul Dryden:

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 (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-reporting-combination-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-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
