About Us

AMT Medical

Together with the UMC Utrecht we developed a new, better way to perform heart bypasses. 

At our office in Utrecht, we have created an inspiring environment. Next to our spacious offices, our laboratory is just a few steps away.

The story

In 2004, Prof. Dr. C.A.F. Tulleken worked together with the University Medical Centre Utrecht to launch the Elana Brain Bypass, in which a bypass can be made in the brain without need of sutures. This technique still saves many lives a year.

Years later, he invented a way to alter the technique and make it applicable to the heart. A much more common problem, but just as important. To ensure the technique worked perfectly we begun AMT Medical.  

Our mission

Our aim is to make the AMT heart bypass the new standard of heart-bypass procedures and lead the way for a new era of medical solutions.
