 It was clear that Lena would need an external support that would do the job instead of her own heart. Just because they couldn't copy the heart 50 years ago doesn't mean we can't sit now. There are some devices out there which actually give us help. Working at BerlinHeart gives you some very unique kind of challenges. Of course you have a quite different view on your challenges when at the end of the line a life depends on it. The heart itself is just a simple pump and so with our ventricular assist device we are building a kind of add-on for the heart. So the heart and the VAD share the load. The heart then can take it quite easy for some time until you're healed. The challenges are not only technical but very medical, a lot of bioengineering. The variance of the physiology is different from one children to another. The testing is important and that's where the AI system is helping by simulating the human body for us. Measurement devices from an AI combine the sensors we need right now. Almost all of the challenges for a blood pump are more challenging when you want to build a device for children. When Jennifer was born we were told that her only chance of survival would be a heart transplant. The younger they are the harder it tends to be on their bodies. It was clear that she was not going to survive her weight unless drastic measures were taken. Our only option was the X-Core system. There were no other options to keep Jennifer alive. X-Core is like unique to the world. You cannot compare to other products. You need to show that your product is doing what it should do and you can only do that by testing. We try to substitute the physiological parameters of a body. You get pressure, you get temperature control. You need to start to think about what happens if it's raining outside, what happens if it's 35 degrees outside. We are using an AI equipment on a daily basis so we can see different small failures in the product which we can only see by testing. I'm highly motivated to go to work as I know that my work is helping other people. Juniper, altogether, she was on the X-Core system four and a half months. The day that we left the hospital then it really hit home that we got to finally take our baby home and start our new normal with her. If there was no X-Core system she would never have survived. If I could say something to the engineers that helped make the X-Core system, I would say thank you. They have saved not only my child but countless children who would never have a chance to make it to transplant if it wasn't for their hard work. Do you remember the machine that mommy has shown you that you had to have saved my life? Hi baby, I love you.
