About the company

Medical 21 is a developmental-stage medical technology company dedicated to revolutionizing coronary artery bypass grafting (“CABG”) surgery. Our flagship product, the MAVERICS small-diameter synthetic regenerative graft, is an investigational device designed to serve as an alternative conduit to harvested autologous vessels. By potentially reducing or avoiding the need for traditional vessel harvesting, MAVERICS is intended to simplify the CABG procedure and decrease patient morbidity associated with additional surgical incisions. MAVERICS has not been approved by the U.S. Food and Drug Administration (“FDA”) or any foreign regulatory authority, and its safety and efficacy have not been established.
