Experiments with simple pumps to substitute for the heart show promise. This seems like an amazing demonstration of paradigm shift! For more than 30 years we’ve been trying to develop artificial hearts that pump in pulses like the human (and most other living things, even insects!) heart. No one apparently thought to try a simple rotary pump like we use in thousand of other application needing …. a pump. Now some one has tried a rotary pumps as a replacement for a calf’s heart, and a person with some success.
The desire to imitate nature was wrong. This is just like the attempt to make flying machines with flapping instead of simple fixed wings.
The rotor pump seems to get around the drawbacks of pulsing pumps that lack durability. The gentlemen who was a test subject, with some success but died of other issue, ironically worked on pumps for the city Houston. Read the link, it’s cool.
