No
The device is described as a "general purpose diagnostic ultrasound system" intended for "ultrasound imaging, measurement, display and analysis," which indicates a diagnostic rather than a therapeutic purpose.
Yes
The device's "Intended Use / Indications for Use" section explicitly states "This device is a general purpose diagnostic ultrasound system..." and its function is described as acquiring and displaying ultrasound data for imaging, measurement, display, and analysis of the human body and fluid, all of which are diagnostic activities. Furthermore, the device name itself, "TE Air Diagnostic Ultrasound System," includes the word "Diagnostic."
No
The device description clarifies that "TE Air consists of an app which can be installed on iOS or Android devices, and probes which use wireless technology for communication." The probes are physical hardware components necessary for the device's primary function of acquiring ultrasound data. Therefore, it is not a software-only medical device.
No.
The device is an ultrasound system used for imaging the human body, not for in vitro testing of specimens derived from the human body. IVDs specifically involve testing biological samples outside the body to diagnose conditions.

Dear Jufang Shi:
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"

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).

|---|---|---|---|
| 1. Primary predicate device | Mindray | TE Air | K240906 |
As compared with the primary predicate device TE Air in K240906, the subject device has the modifications described as following.
New added options
| 1 | Add AirSight. The TE Air consists of an app which can be installed on iOS or Android devices, and probes which use wireless technology for communication. The iOS or Android devices could be mobile platform available from the market, or the Mindray's Customized Android platform called AirSight. The AirSight is introduced in this application. |

Page 4 of 6
The AirSight is a device composed of the processor, memory, display screen, audio module, wireless module, battery, Android software operating system, sheet metal, and housing. The final form of AirSight is similar to a mobile phone. The AirSight, ultrasound probe and TE Air APP form a complete Ultrasonic imaging system for ultrasound imaging, measurement, and display.
The TE Air Diagnostic Ultrasound System has the similar technological characteristics, is comparable in key safety and effectiveness features, and has the same intended uses and basic operating modes as the predicate devices. All systems transmit ultrasonic energy into patients and perform post processing of received echoes to generate onscreen display of anatomic structures and fluid flow within the body. All systems allow for specialized measurements of structures and flow, and calculations.
• The subject device and predicate TE Air (K240906) have same clinical indications for use.
• The subject device and predicate TE Air (K240906) have identical imaging modes, same special functions
• The acoustic power levels of subject device are below the limits of FDA, which is the same as the predicated device TE Air (K240906).
• The proposed TE Air has a software app which can be installed on user's mobile device that provides some of the processing and uses the screen of the mobile device as the display like is done for cleared TE Air (K240906). The AirSight is newly introduced in the proposed TE Air, and this change has passed the related bench tests, no safety risk is introduced.
