#### Note 1

Although there is a little difference about the cation for use, the meanings are the same. This difference does not affect he safety and effectiveness.

## Note 2

Although the subject device design and specification parameter between the predicate are different, they are both complied with ANSVAAM ES60601 -1. So the minor differences on such parance) do not affect the safety and effectiveness.

### Note 3

Although the device provides four kind sleeves which have minor difference about size and appearance, the sleeve chamber number are the same and the applicable body areas are included in the predical of sleeves is also complied with ISO 1099-5 and ISO 10993-10. Therefore, the difference would not raise adversely impact on safety and effectiveness.

### Note 4

Although the pressure range of subject devices, the range is smaller and contained by the predicate device (1), sothe difference of pressure range would not raise adversely impact on safety and effectiveness.

### Note 5

Although the treatment time range of subject device is to 99mins, which seems to be longer than the predicated with is suitable for daily use. And the treatment time is optionally set by userwith 5mins step, which is more exact to the difference of pressure range would not raise adversely impact on safety and effectiveness.

{14}------------------------------------------------

## Note 6

Although the subject device provides six kinds of work mode, the SEQUENTIAL and FLUSH mode are the same with the other work modes of subject device just have different about the different thambers. The treatment pressure range are the same under different work modes, so the difference of pressure range would not raise adversely impact on safety and effectiveness.

## Note 7

The subject device references more sufficient safety standards than the safety of the safety of the device is verified via tests.

## 7. Summary for clinical test

Clinical performance is not deemed necessary.

### 8. Conclusion

The subject device Compression Therapy Device has all features for intended use. Thus, the subject device is substantially equivalent to the predicate devices.
