Impella physics and physiology. How does Impella operates? What is Impella? 

Impella device is a heart pump. 

This is a summary; more information is available in our YouTube video.





1. This device is at its core, it's nothing more than a propeller.

Its design creates suction at one end and ejection at the other. 

2. Impella device is a microaxial pump. So, the flow it generates follows the principles of such machines

3. Impella catheter is an axial pump and the primary factor determining flow and current in the same patient is pressure difference. 

4. The axial pump mechanism of the Impella is not completely isolated from the bloodstream. This would result in some blood flow entering the system

5. Pressure measurement. 

The device can determine pressure in real time using optical fiber and laser. 

6. The system can estimate the left ventricular pressure and display a real-time curve, as well as estimate the left ventricular end-diastolic pressure. 

7. The Impella software can infer, based on an initial measurement, the evolution over the following hours of total cardiac output, native output, and cardiac power output.
