FlowAid Medical Technologies, a company based in New York City, won FDA clearance for its FA100 Sequential Continuous Contraction Device (SCCD). It’s designed to help promote blood circulation, reduce swelling, prevent atrophy, and lower the chances of venous thrombosis in post-surgical patients by electrically stimulating the calf muscles.
Unlike many other muscle stimulators, the FA100 creates a pattern of contractions that compress veins in the lower leg, generating a blood outflow greater than the patient’s own. It’s similar to pushing in one direction on a hose filled with water to make the water flow outward. As the veins become more active the flow through the arteries follows suit.
There’s no pressure actually applied to the legs, and unlike powered pressure devices, the FA100 is small and the electrodes easy to apply.
Here are where the electrodes positioned to create a proper pumping action:
