Reshaping the Future of Cardiac Bypass Surgery

We are a developmental stage medical technology company that is revolutionizing heart bypass surgery with an artificial graft called MAVERICS. Founded by Manny Villafaña, Ph.D.Sc., a “Living Legend of Medicine,” our company has developed a graft that allows the heart bypass procedure to be done without harvesting vessels from the body.

About Medical 21

With roughly one million heart bypass surgeries performed each year worldwide and cardiovascular disease as the #1 cause of death globally, clinicians need a better option for a complete revascularization procedure of the heart.

Our MAVERICS graft is a small-diameter flexible tube encased in a nitinol scaffold that eliminates the need to harvest blood vessels from the patient’s legs, arms, and chest. This leads to a higher quality of life for the patient through less pain, decreased procedure and recovery time, and lower risk of infection and complications.

By eliminating the need to harvest vessels from a patient’s arm, leg, and chest, surgical teams can save time and help patients who can then recover faster without additional scarring, pain, or post-op complications.

Our revolutionary artificial graft allows those who currently cannot have bypass surgery — such as people with amputations, severe diabetes, or varicose veins — to be considered for the procedure.

Our History

The Medical 21, Inc. team has a long, proven history of creating incredible and lasting value in the medical device industry. Medical 21 is Manny Villafaña’s eighth medical device company, having led the previous seven to IPO financing.

In 1972, Manny Villafaña founded CPI/Guidant in Minnesota and developed the very first lithium-powered pacemaker and defibrillator. His technology is incorporated into virtually every defibrillator and pacemaker around the world.

CPI/Guidant was purchased by Boston Scientific for $27 billion.

St. Jude Medical, Inc. was recently purchased by Abbott Medical of Chicago for $30 billion.

Villafaña then founded ATS Medical and developed the next-generation ATS heart valve, now part of Medtronic, Inc. through a purchase of $400 million in 2010.
