The Artificial Heart
By Bridget Finn

(Business 2.0) – It's noisy, but it's for real: the first federally approved artificial heart. The U.S. Food and Drug Administration gave the go-ahead this autumn to CardioWest, a titanium-valved heart designed to extend the lives of patients awaiting transplants. Developed by Arizona-based SynCardia Systems, the $100,000 device replaces the bottom half of the heart. Tubes connect it to an external power supply that regulates flow and pressure. In clinical trials, 64 of 81 patients survived long enough—in one case more than 13 months—to receive a donor heart. — BRIDGET FINN
