By six months after the initial treatment, these patients averaged more than 5 mm of new growth, Erchonia reported. The patients were between 18 and 70 years old, and received treatments once a week for four weeks. The 510(k) is a premarketing submission to the FDA that demonstrates that the device marketed is safe and effective, and is the most rigorous type of device marketing application accepted by the FDA. Researchers at Erchonia cited no known side effects across four clinical studies of the device, which could avoids the toxicity potential of previous oral antifungal medical treatments.
