| | Diagnostic Ultrasound System |

Labat series Diagnostic Ultrasound System has the same technology as the predicate device(K180912). The proposed device has the same intended uses and similar operation modes as the predicate device. All systems have the same capability in term of measurements and calculation functions .

The proposed device has the same intended uses and probe type as predicate device TE7/TE5(K180912);

The acoustic power levels of the proposed device are below the limits of FDA, which is the same as the predicate device (K180912);

The proposed device has similar operation modes as the predicate device TE7/TE5(K180912), except for Holo PW, AMM and TDI. For Holo PW and TDI, it has been cleared in reference device (K163712). For AMM mode, it can be considered same as reference device (K201693);

The proposed device has the same function, except for Needle Guide System(wiGuide), which detects the position and orientation of magnetized needles in the presence of the probe and displays this information relative to the ultrasound image. This function has similar operating principals and specifications as the reference device (K180461);

This difference in technological characteristics do not raise different questions of safety and effectiveness as compared to the predicate device.

6. Performance Data

The following performance data were provided in support of the substantial equivalence determination.

# Biocompatibility testing

The biocompatibility evaluation for the Labat series Diagnostic Ultrasound System was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk

The software for this device was considered as a "Moderate" level of concern.

## Acoustic testing

Acoustic testing is conducted on the Labat series Diagnostic Ultrasound System in accordance with the NEMA UD 2-2004 (R2009), acoustic output measurement standard for diagnostic ultrasound equipment revision 3.

## Clinical study

The subject of this premarket submission, Labat series Diagnostic Ultrasound System, did not require clinical studies to support substantial equivalence.

## 7. Conclusion

The differences between the Labat series Diagnostic Ultrasound System and its predicate device do not raise different questions of safety and effectiveness. The non-clinical data support the safety of the device and the performance testing report demonstrate that the Labat series Diagnostic Ultrasound System should perform as intended in the specified use conditions.

From the results of performance data described, Shenzhen Wisonic concludes that the Labat series Diagnostic Ultrasound System is as safe and as effective as the predicate devices.
