Medical 21 is raising funds on Rialto Markets through Reg A+ crowdfunding. It is a medical technology company that is revolutionizing heart bypass surgery with an artificial graft. The graft, MAVERICS, allows the heart bypass procedure to be done without harvesting vessels from the body. MAVERICS is a small flexible tube encased in a nitinol scaffold and leads to less pain, decreased procedure and recovery time, and lower risk of complications. Dr. Manny Villafana founded Medical 21 in 2016. The current crowdfunding campaign has no minimum target and a maximum target of $40,000,000. The campaign proceeds will be used for marketing, clinical studies, scaling manufacturing capacity, and working capital.
