The circulatory system is a closed system at a mean pressure....

The circulatory system is a closed system at a mean pressure. The heart sits in the middle of it. It creates a pressure gradient. Now there is an area of lower pressure and an area of higher pressure. What moves the blood around is the difference in pressure, it flows from higher pressure to lower pressure.
Imagine a field with a pond at the bottom end a water wheel with cups on it and a pond at the top end.
If the water wheel isn't working the pond at the bottom end fills to the same level as the pond at the top end and no water (blood) flows. Get the water wheel working and it lowers the level of the bottom pond and raises the level of the top pond. Water (blood) flows. The water wheel isn't "pushing or Pulling " the water (blood ) round the field ( body). The water wheel and the heart are just a specific mechanism in the system that create a potential difference.
It's the pressure difference that moves the water/ blood.
So how do you move water around the field to where you want it? How do you balance the system?
An array of elastic pipes that you can alter resistance with.
What happens in heart failure.
The water wheel(heart) doesn't work as well.
It struggles to turn so the "cups" don't fill and empty as well. Because the cups (ventricles) are not filling and emptying properly enough not enough potential difference is created for the body to naturally work its elastic pipes and get blood flowing round the system.
By radically altering the elasticity of the aorta C-Pulse allows the body to operate its blood distribution system at a lower potential difference.
C-Pulse is going to work if the potential difference isn't just too low and damage in the heart and around the pipes isn't too great to support even a reduced pressure difference and able to heal.
Surely an indirect problem of minimally invasively implanting leads can be solved.
