Intended Use

The Overlapped Compression Therapy is indicated for the temporary relief of minor muscle aches and pains and for temporary increase in circulation to the treated areas in pood health. The Overlapped Compression Therapy simulates kneading and stroking of tissues by using an inflatable garment.

Device Description

The Overlapped Compression Therapy consists of leg sleeve and control device working together as one unit. The Overlapped Compression Therapy mainly forms the circulating pressure on the limbs and tissues by repeatedly inflating and deflating the multi cavity chambers in sequence, and evenly, orderly and properly extrudes the distal end of the limbs to the proximal end of the limbs.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device called "YY-A02-B Overlapped Compression Therapy." This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving novel safety and effectiveness through extensive clinical trials. Therefore, the information provided focuses on comparative analyses and bench testing against established standards, rather than clinical efficacy studies with acceptance criteria in the typical sense of a diagnostic or therapeutic AI device.

Below is an attempt to address your request based on the provided document, acknowledging that most of the requested categories are not applicable to this specific type of submission.

Acceptance Criteria and Device Performance

The document does not explicitly state "acceptance criteria" in the format of specific sensitivity, specificity, or similar performance metrics that would be typical for an AI/diagnostic device. Instead, acceptance is based on demonstrating substantial equivalence to a predicate device and adherence to recognized safety and performance standards. The "device performance" is reported as compliance with these standards and successful completion of bench tests.

To structure this for your table, I will interpret "acceptance criteria" as meeting regulatory standards and demonstrating comparable performance to the predicate in key technical specifications.

Acceptance Criteria (Interpreted)Reported Device Performance

Similarity and Difference

The YY-A02-B Overlapped Compression Therapy has been compared with the Air Compression Therapy Device. The subject device has same intended use and principle of operation, similar technological characteristics as that of predicate device. Although there are several specifications that are different between the subject device and predicate device, the comparison analysis has been completed to demonstrate that the differences between these parameters would not adversely impact the safety and effectiveness of the subject. The subject device has undergone safety and performance tests, and the results complied with the test requests. Therefore, the difference between the subject device and the predicate devices do not raise any problem of substantial equivalence. The subject device is substantially equivalent to the predicate device in safety and performance claims.

Note 1: The level of air pressure and pressure range is different. the level of air pressure of the subject is 5 level and the predicate device is 3 level. The minimum air pressure (0 mmHg) of subject device is the same as the predicate device. the air pressure of subject device (210 mmHg) is within the range of the predicate device. Additionally, the subject device conforms to ANSI/AAMI ES60601-1 and ISO 14971, so the small differences do not affect the safety and effectiveness. Although the "air pressure level /compression levels" of subject device is different to the predicate devices, but they output air pressure range are similar, so the pressure level different do not affect the safety and effectiveness

Note 2: The subject device has a smaller pressure error range than the predicate device. So the small difference do not affect the safety and effectiveness.

Note 3: Although the "Cycle time" of subject device is different the predicate devices, but the range of cycle time is less than predicate device. So the small difference do not affect the safety and effectiveness

Note 4: The "anatomical locations of applications" of the subject device is different. It not contains the upper leg. The small difference do not affect the safety and effectiveness.

Note 5: Although the "sleeve materials" of the subject device is different from the predicate device, but the subject device complies with the requirements of the biocompatibility standards. So the difference do not affect the safety and effectiveness.

Note 6: Although the "Number of chambers" of subject device is different to the predicated device, but due to the chamber number only determines the applicable treatment site, while the "applicable treatment site" and "Indications for Use" of subject device is within the range of predicated device. So the differences do not affect the safety and effectiveness.

Note 7: Although the "Inflation & deflation time" of subject device if different to the predicated device. For the safety: the subject device has compliance with IEC 60601-1 and ISO 14971 standards. And the subject device has designed the pressure sensor to protection the over-pressure, so the subject device was safety. For the effectiveness: since the treatment mode, treatment pressure and cycle time of the subject device is similar to the predicate devices, so we can be considered that

{11}------------------------------------------------

the subject device and predicate device had similar effectiveness. Based on the above analysis, can be considered the small difference will not affect the safety or effectiveness issue

Note 8: Although the "power consumption" of the subject device is different than the predicate devices, they both comply with ANSI/AAMI ES60601-1, so the difference does not affect the safety and effectiveness.

Note 9: Although the "Transportation environment" of the subject device is different than the predicate devices, they comply with ANSI/AAMI ES60601-1, so the difference does not affect the safety and effectiveness.

Note 10: Although the "Weight" between the predicate devices and subject device is different, they are both complied with ANSI/AAMI ES60601-1 and IEC 60601-1-2, so the differences do not affect the safety and effectiveness

Substantial Equivalence Conclusion
