"The pump also has a curious side effect: people implanted with the device have no pulse. The VentrAssist, which is made by Australian company Ventracor, is of a type known as left ventricular assist devices... Most LVADs attempt to mimic the way the heart works, but their complicated design makes them prone to failure... 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."
