Article: Simpler pump boosts failing hearts| New Scientist: "Most LVADs attempt to mimic the way the heart works, but their complicated design makes them prone to failure, and they have a tendency to make blood pool and clot, leading to strokes. That means LVADs are usually only used as a last resort for patients waiting for heart transplants.

What makes the VentrAssist different is that it only has one moving part, a spinning impeller that drives a continuous stream of blood. That means the pulse is replaced by a gentle whirling noise that patients describe as similar to the sound of a washing machine. More importantly, the device prevents blood from stagnating, reducing the risk of clotting."
