Renata Medical

At Renata Medical, we are redefining how congenital heart disease is treated—starting with the smallest patients and the biggest challenges. Built in close partnership with physicians, families, and hospitals, our innovations are grounded in real clinical needs and long-term outcomes. We exist to push the field forward—and to help more children live longer, healthier lives. In August, 2024, the Minima Stent System became the first and only FDA-approved stent designed for neonates, infants, and young children. Not only can it be implanted in small vessels, but can also be expanded over the course of their adolescence up to adult sizes. The Minima Stent System is currently available in the U.S., with plans to expand access to Europe and Asia in the near future.
