Intended Use
To aid in the detection of platelet dysfunction in citrated human whole blood.
Device Description
The PFA-100® system provides a tool for clinicians to use in the detection of platelet dysfunction induced by intrinsic platelet defects, von Willebrand factor (vWF) functional deficiencies, or exposure to platelet inhibiting agents. The PFA-100® system simulates, under high shear stress, the interaction of platelets with an injured blood vessel. These conditions allow the PFA-100® system to measure in vitro platelet function as related to primary hemostasis.
More Information

No
The summary describes a mechanical system that simulates blood flow and measures platelet function based on closure time. There is no mention of AI, ML, image processing, or data-driven algorithms for analysis or interpretation.

No.

The device is designed to aid in the detection of platelet dysfunction, providing a tool to measure in vitro platelet function. It does not directly treat a condition or restore a bodily function, which are characteristics of a therapeutic device.

Yes

The "Intended Use / Indications for Use" states, "To aid in the detection of platelet dysfunction in citrated human whole blood." The "Device Description" further clarifies it "provides a tool for clinicians to use in the detection of platelet dysfunction." These phrases clearly indicate a diagnostic purpose.

No

The device description explicitly states "The PFA-100® system provides a tool..." and "The PFA-100® system simulates...". This language, along with the description of simulating physical processes ("interaction of platelets with an injured blood vessel"), strongly suggests a hardware component is involved in the testing process, not just software for analysis or display. The predicate devices also refer to a "Platelet Function Analyzer," which is typically a physical instrument.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states "To aid in the detection of platelet dysfunction in citrated human whole blood." This indicates the device is used to analyze a biological sample (blood) outside of the body to provide information about a medical condition (platelet dysfunction).
  • Device Description: The description further clarifies that the system "measures in vitro platelet function as related to primary hemostasis." "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
  • Sample Type: The device uses "citrated human whole blood," which is a biological specimen.
  • Purpose: The purpose is to aid in the detection of a medical condition (platelet dysfunction).

All of these points align with the definition of an In Vitro Diagnostic device.

Dear Mr. Riesgo:

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.

If your device is classified (see above) into cither class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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 Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820). This letter

will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (240) 276-0484. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150, or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html.
