About Us

What do we aim for?

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 our dream becomes tangible.
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 a shorter recovery time for the patient. Within a few days he or she can go home and do the things they enjoy, without pain and dysfunction. 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. 

Our ambition

Partnership is important for us

Together we are better

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 where the procedure is put into clinical practice. Partnership is important for us so we work with clinical specialists, advisors and our investors on a daily basis.
We firmly believe “Together we are better”.
Our AMT team is key to reaching our goals. We have a diverse team of junior and senior members, who are extremely experienced in R&D innovations, quality, regulatory guidelines and bringing clinical solutions to patients.
