I'd be curious to see how the device scales up flow for more vigorous activity. Does it measure adrenaline as a means to increase flow and blood pressure?
Coolest thing i've ever seen.
I was wondering about that too. Your heart automatically adjusts its rate when you become active and your tissues need extra oxygen or even if you are in high-altitude environment. But how would this device know when your body needs more oxygen? I can't imagine it would. Maybe this is just a temporary measure until they can get him a heart transplant.
Blood flow: You could measure the motion of the body with an acceleration sensor and regulate the flow accordingly.
Energy: There are blood glucose fuel cells to generate power, but they are not efficient enough at the moment to power that pump.
