Patient Michael B. received an alfapump® in 2012 and he has not looked back since. The alfapump® System helped Michael to improve his appetite and physical activity level. He responded so well to therapy that he is no longer being considered for a liver transplant.

It has been amazing, really!

Michael B.

“…once the alfapump was switched on it started to drawn the fluid away, it was set to a certain level, I think it was a litre a day to start off with, and things just got better fairly quickly.
… It has given me a new lease on life, essentially. Before, I was struggling with lack and breath, lack of appetite, not really wanting to do anything or being unable to do a lot of things, sleeping a lot. The alfapump® has removed the fluid that was surrounding my lungs and other organs and it has been amazing, really!”
