The document describes a standard ultrasound imaging system and its functionalities, with no mention of AI or ML technologies in the intended use, device description, or performance studies.
No
The device is described as an "Ultrasound Imaging System" intended for "evaluation by ultrasound imaging system or fluid flow analysis" and "diagnosis of patients." Imaging and diagnosis are not therapeutic actions.
Yes
The "Intended Use / Indications for Use" section explicitly states that the system is "intended for use by qualified physicians and healthcare professionals who has the ability to conduct ultrasound scan process for evaluation by ultrasound imaging system or fluid flow analysis of the human body" and that "The clinical environments where the system can be used include physician offices, clinics, and clinical point-of-care for diagnosis of patients." The term "diagnosis" directly indicates a diagnostic purpose.
No
The device description explicitly states that the system consists of wireless transducers with built-in batteries, beamformers, and Wi-Fi components, which are hardware components. While the software runs on a mobile device, the overall system includes dedicated hardware for image acquisition and transmission.
Based on the provided information, the Leltek Ultrasound Imaging System (Model: LU700 Series) is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body, such as blood, urine, or tissue, outside of the body to provide information for diagnosis, monitoring, or screening.
- Leltek Ultrasound System Function: The description clearly states that the Leltek Ultrasound Imaging System is used to acquire and display real-time ultrasound data of the human body directly. It uses ultrasound waves to create images of internal structures and fluid flow.
- Intended Use: The intended use describes various clinical applications and exam types performed on the patient's body (e.g., abdominal imaging, cardiac imaging, musculoskeletal imaging).
- Device Description: The device description details the hardware and software used to generate and display ultrasound images from within the body.
The device is an in vivo diagnostic imaging system, not an in vitro diagnostic device.

Device Description
The Leltek Ultrasound Imaging System (Model: LU700 Series) is a portable, software controlled, handheld ultrasound system used to acquire and display hi-resolution, real-time ultrasound data through a commercial off-the-shelf (COTS) mobile device.
- I. The imaging system software runs as an app on a mobile device.
- II. The imaging system software can be download to a commercial off-the-shelf (COTS) mobile device and utilizes an icon touch-based user interface.
- III. The imaging system consists of a series of wireless transducers employing Wi-Fi-based technology to communicate with traditional tablet/smartphone devices via direct Wi-Fi. This allows the user to export ultrasound images and display them across a range portable personal device.
IV. The imaging system houses a built-in battery, multichannel beamformer, prescan converter and Wi-Fi components
The device is intended for use in environments where healthcare is provided by trained healthcare professionals, but not intended for use in emergency medical service, ambulance, or aircraft.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The Leltek Ultrasound Imaging System has been evaluated for acoustic output, biocompatibility, cleaning and disinfection effectiveness as well as wireless, thermal, electrical, electromagnetic and mechanical safety and has been found to conform with applicable medical device safety standards. The Leltek Ultrasound Imaging System did not require clinical testing to establish substantial equivalence.
The new models comprise LU710L, LU710LH, which are tested and determined to be in full compliance with acoustic output, biocompatibility, cleaning, and disinfection effectiveness, and have no pragmatic detriments. No additional clinical testing is required. The maximum acoustic output level is under the FDA recommended limit, and the power level is displayed all the time. All the safety and performance tests of the device meet the essential requirements. Therefore, the system is substantially equivalent to predicate devices.
Verification and validation testing have been conducted on the Leltek Ultrasound Imaging System and ascertain that it is safe for use by physicians.

Evaluation per standard AAMI/ANSI/ES60601-1 and IEC 60601-1-2 were performed for use of the transducers with a specific computer model (Panel PC Xiaomi/M1806D9W) and adaptor (Model A1385) to charge the medical device. Use of alternate compatible computer hardware requires verification by the end user. Further information is provided in the user manual.
The Leltek Ultrasound Imaging System has been evaluated for acoustic output, biocompatibility, cleaning and disinfection effectiveness as well as wireless, thermal, electrical, electromagnetic and mechanical safety and has been found to conform with applicable medical device safety standards. The Leltek Ultrasound Imaging System did not require clinical testing to establish substantial equivalence.
9. General Safety and Effectiveness
This device is the addition of new transducer models to the Leltek Ultrasound Imaging System, using technologies existing on the market as of the date of this submission. The Leltek Ultrasound Imaging System (Model: LU700 series) meets FDA requirements for Track 3 devices, have biosafety equivalence, and conform to applicable electromedical devices safety standards.
The new models comprise LU710L, LU710LH, which are tested and determined to be in full compliance with acoustic output, biocompatibility, cleaning, and disinfection effectiveness, and have no pragmatic detriments. No additional clinical testing is required. The maximum acoustic output level is under the FDA recommended limit, and the power level is displayed all the time. All the safety and performance tests of the device meet the essential requirements. Therefore, the system is substantially equivalent to predicate devices.
10. Conclusion
Verification and validation testing have been conducted on the Leltek Ultrasound Imaging System and ascertain that it is safe for use by physicians. The 510(k) submission is the modification of the existing licensed device using technologies that exist on the market today and demonstrating the new transducers of the Leltek Ultrasound Imaging System are substantially equivalent in safety and effectiveness to the predicate device.
