The summary describes a system that stimulates blood flow to prevent DVT, but there is no mention of AI, ML, or any related technologies in the provided text.
Yes
The device is described as aiding in the prevention and treatment of various medical conditions, such as DVT, stasis dermatitis, venous stasis ulcers, and chronic venous insufficiency, which directly aligns with the definition of a therapeutic device.
No
The "Intended Use / Indications for Use" section clearly states the device is for prevention and treatment (e.g., aid in prevention of DVT, enhance blood circulation, reduce wound healing time, aid in treatment of various conditions), not for diagnosis. There is no mention of identifying a disease or condition.
No
The description explicitly states the device is a "system" intended to stimulate blood flow in the extremities, which strongly implies a hardware component is involved in delivering the stimulation. The description does not mention software as the sole component.
Based on the provided information, the Devon 24R deep vein thrombosis prevention system is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Devon 24R Function: The description clearly states the device works by "stimulating blood flow in the extremities (simulating muscle contractions)" to prevent DVT and aid in the treatment of various conditions. This is a physical intervention, not a diagnostic test performed on a sample.
The device's intended use and mechanism of action are entirely external to the body and do not involve analyzing biological samples.
N/A
Intended Use / Indications for Use
The Devon 24R deep vein thrombosis prevention system is intended to be an easy to use portable system, prescribed by a physician, to help prevent the onset of DVT in patients by stimulating blood flow in the extremities (simulating muscle contractions).
This device can be used in the home or clinical settings to:
- Aid in the prevention of DVT
- Enhance blood circulation
- Diminish post-operative pain and swelling
- Reduce wound healing time
- Aid in the treatment of: stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency and reduction of edema in the lower limbs
- As a prophylaxis for DVT by persons expecting to be stationary for long periods of time

Dear Julian Chu:
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. 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 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good

manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
