No
The device description focuses on mechanical inflation/deflation and air pressure, with no mention of AI or ML algorithms for control, analysis, or prediction. The performance studies are based on non-clinical product performance tests comparing to a predicate device, not on the performance of an AI/ML model.
Yes
The device is described as a system to prevent DVT (Deep Vein Thrombosis) and improve blood velocity, which are therapeutic actions. It also lists indications such as Edema and Leg Ulcers, further supporting its therapeutic nature.
No
This device is designed to prevent DVT by improving blood velocity through continuous inflation/deflation of sleeves, which is a prophylactic and therapeutic action, not a diagnostic one. It does not identify or confirm the presence of a disease.
No
The device description explicitly mentions hardware components like "sleeves," "pump," "air pressure," "air motor," and "solenoid valve," indicating it is a hardware-based device with software control, not a software-only medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to prevent DVT and treat various circulatory issues by physically manipulating blood flow through external compression. This is a therapeutic and prophylactic function, not a diagnostic one.
- Device Description: The device works by applying external pressure to the limbs using air-filled sleeves. This is a mechanical action, not a process that analyzes biological samples (like blood, urine, or tissue) to diagnose a condition.
- Lack of IVD Characteristics: There is no mention of analyzing samples, using reagents, or providing diagnostic information based on biological markers.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Test Summary: The DVT-PRO complies with voluntary standards for electromagnetic compatibility. And a biocompatibility test was conducted for the sleeves, not for device, an accessory used with DVT-PRO. In addition, it was confirmed that the performance of the product was satisfactory by conducting a performance test to prove that it is substantially equivalent to the equivalent device.
- Electrical Safety, Electromagnetic Compatibility and Performance: The DVT-PRO complies with the electrical safety and electromagnetic compatibility requirements established by the standards.

Dear Su Hyeon So:
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 (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 located 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.
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

The table also provides rationale for a little difference in support of substantial equivalence to the Predicate devices.
[Table 2. Little differnence with Predicate Device]
Justification to Support Substantial Equivalence
The DVT-PRO(Proposed device) is hardly different from the DVT-PRO(Predicate device) except pressure error range, Adaptor power consumption etc.,.
For the power consumption of the adapter,
In the traditional 510(k) of K150980, it was confirmed that it was mislabeled as a typo, So, we want to correct it to the correct numerical value by changing it to 18W.
In the case of the pressure error range, there is no additional risk since it is changed to a tighter condition.
Therefore, differences in technical characteristics do not affect safety and effectiveness.
Non-Clinical Test Summary
The DVT-PRO complies with voluntary standards for electromagnetic compatibility. And a biocompatibility test was conducted for the sleeves, not for device, an accessory used with DVT-PRO. In addition, it was confirmed that the performance of the product was satisfactory by conducting a performance test to prove that it is substantially equivalent to the equivalent device.
The following data were provided in support of the substantial equivalence determination :
4 / 5

- Electrical Safety, Electromagnetic Compatibility and Performance
The DVT-PRO complies with the electrical safety and electromagnetic compatibility requirements established by the standards.
· IEC 60601 : 2005/A1:2012, Medical Electrical Equipment:Part 1: General Requirements for Basic Safety and Essential Performance
- · IEC 60601-1-2:2014, Medical Electrical Equipment Part 1 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Disturbances -Requirements and Tests
· ISO 10993-5:2009 Third edition 2009-12-15, Biological evaluation of medical devices - Part 5: Tests for in vitro cytotoxicity
· ISO 10993-10 Thrid Edition 2010-08-01, Biological evaluation of medical devices - Part 10: Tests for irritation and skin sensitization
- Non-clinical test (Product performance test)
· A test was conducted that reflected the difference from the equivalent device, and after the change, it was confirmed that the product satisfies the existing performance. Therefore, it can be confirmed that the existing predicate device(K150980) and the proposed device(K203353) are substantially equivalent.
Clinical Test Summary
Clinical testing was not required to demonstrate the substantial equivalence of the DVT-PRO to its predicate device.
8. Conclusion [21 CFR 807.92(b)(3)]
The DVT-PRO has same indication for use and technical characteristics to the predicate device except some item. Based on that information, we conclude that the differences between the proposed device and predicate device do not introduce a new intended use and do not raise new issues of safety and effectiveness.
