About us

bypassing open heart surgery

Our ambition

We have one big dream: to banish open heart bypass surgery from the world.
Up until recently, that seemed a distant prospect. Well, not anymore. Today it’s right in front of our eyes.
Our technique enables the bypass surgery to be performed through small holes in the chest. No split ribcage. No heart-lung machine. No stopping of the heart. Not even sutures. Yes, it’s that minimally invasive.
This means less implications during surgery and shortening the recovery time of the patient significantly. Within a few days he or she can go home and do the things they enjoy, without pain and disfunction.
That is why we want to make this the new standard in coronary bypass surgeries, improving the quality of life for millions of people. And we can do that, starting today. By making the open heart surgery a procedure from the past..

AMT Medical

Together with the UMC Utrecht, the Netherlands we developed a new and better way to perform heart bypasses. The Antonius hospital Nieuwegein, the Netherlands and The German Heart Center in Berlin, Germany are the expert centers to use the procedure into clinical practice. Partnership is important for us so we work on a daily basis with clinical specialists and advisors and our investors.
We firmly believe “Together we are better”.
Our AMT team is key to reach our goals. A diverse team of junior and senior members, with an extensive track record in R&D innovations, quality, regulatory and bringing clinical solutions to patients. 

Our values

We value people orientation with a passion about innovation and quality. We trust each other and communicate in an open and transparent way. We are ambitious and driven to reach our common mission and vision.
