Welcome to the OVA Solutions knowledge hub. Here we share what we have learned building medical devices: prototyping and design transfer, what development actually costs and how long it takes, and the regulatory path through the FDA, ANVISA and COFEPRIS. Real numbers from real projects, not generalities.
