    A gentleman named Craig Lewis, a 55-year-old experiencing a life threatening heart disease, named “amyloidosis”, was admitted to the Texas Heart Institute.

    Amyloidosis (am-uh-loi-DO-sis) is a rare disease that occurs when a substance called amyloid builds up in your organs. Amyloid is an abnormal protein that is produced in your bone marrow and can be deposited in any tissue or organ.

    Luckily, Dr. Billy Cohn and Dr. Bud Frazier from the Institute came up with what they call a “continuous flow” device which would let blood to circulate through his body without a pulse.

    They detached Mr Lewis’ heart and then connected the device -the patient was up, well and speaking with doctors in the same day.

    The device is formed by intricately tying together two ventricular assist devices, replacing the entire heart, It whirls instead of pulses, spinning blood through the body in a continuous flow.

    Dr. Cohn is a expert surgeon, as well as an discoverer and scientist who has consumed a large part of his life developing technologies to substitute or repair the human heart. The most distinguished device being what is called the Left Ventricular Assist Device, also termed as LVADs.

    Cohn teamed up with Dr. Bud Frazier to make a new discovery that uses the technology from LVADs to duplicate the functions of the heart’s right and left ventricles. They (inappropriately) tried their device on 70 calves, all of whom gave a flat line on an EKG, no heart rate or pulse, yet they were flawlessly normal, ate normally and related with each other normally but again, had no heartbeat.

    Increadible stuff but I have a question. If the brain regulates fat burning based on heart rate how will the brain decide what to burn and convert fuel wise say during excising, for example a very facepaced paced awalk or slow jog to allow the brain to choose to convert fat to energy, were higher is muscle building and max effort is burning and fast burn fuels in the body such as proteins ?

    He’s has a permanent tracheostomy, and is connected to dialysis via a CVC. What quality of life can this man expect to have? What were the co-morbidities that accompanied the amyloidosis? What level does he function on cognitively?

    That's awesome but that dude isn't looking to good. I have a lot of questions w this though. Like is that tracheotomy permanent & does he have to go to the hospital everyday for dialysis. I hope this works for him & he gets stronger & healthier. Kudos to the doctors for finding alternative ways to treat ppl.

    This was back in 2011. The man had 12 hours to live when they performed the surgery and he got just over another month where he was able to talk to and say goodbye to his friends and loved one before the underlying disease caused his death... (the pumps were still working when his body had died)

    The brain performs this task through an algorithmic biochemical process. The algorithm involved for this particular task should not be overly complicated, and once decoded such an algorithm could easily be utilized to communicate this task to the brain.
