Lucida Medical × Scarlet
Certifying the latest AI model of a Class IIb medical device in 7 days
How Lucida Medical got a product update approved for their MDR-certified, prostate-cancer-detection system in one week
“We transferred to Scarlet because our mission is to detect cancer as early as possible — we need to be able to update our devices regularly and without friction.
Scarlet’s AI expertise and responsiveness meant that as soon as we completed the certificate transfer, we were able to get a product update approved in 7 days.”
Stefani Aleksandrova, Head of Regulatory Affairs, Lucida Medical
