Supplied as a reusable medical instrument, it adheres to FDA 510(k) clearance under the classification of Device Class II (regulation number 870.2780). It requires proper calibration and maintenance in accordance with manufacturer guidelines to ensure accurate and reliable performance.

Frequently asked questions

What clinical conditions is the QuantaFlo designed to evaluate in patients?

The QuantaFlo is specifically designed to detect and assess Peripheral Arterial Disease (PAD) by measuring blood flow and vascular function in the lower extremities. It helps identify early signs of arterial health issues in this region through non-invasive, point-of-care testing.

Is the QuantaFlo intended for use in both clinical and home settings, and how does that affect its design?

Yes, the QuantaFlo is approved for use in both clinical and home settings as a non-invasive, point-of-care tool. Its design prioritizes ease of use, portability, and reliability to accommodate different environments while ensuring accurate vascular function assessment.

How is the QuantaFlo supplied, and does it require any special handling or maintenance?

The QuantaFlo is supplied as a reusable medical instrument, meaning it is not single-use. Proper calibration and maintenance are required to ensure its accuracy and reliability, as outlined in the manufacturer’s guidelines.

What regulatory pathway was followed for FDA clearance of the QuantaFlo, and what does that mean for its classification?

The QuantaFlo received FDA clearance through a 510(k) submission, classified as Device Class II under regulation number 870.2780. This means it was determined to be substantially equivalent to a legally marketed predicate device and is subject to additional controls beyond general controls due to its higher risk classification.

Are there multiple models or sizes of the QuantaFlo, and how would a buyer determine which one to select?

The QuantaFlo is associated with multiple registration numbers and product codes (e.g., JOM), which may correspond to different models or configurations. While the data does not specify exact size variations, buyers should consult the manufacturer’s documentation or contact Semler Scientific for guidance on selecting the appropriate model based on their clinical or home-use needs.
