US doctors implant new artificial heart in Greek man

A team of US doctors has implanted a new kind of artificial heart pump in a patient in Greece that is smaller, longer-lasting and expected to cause fewer clotting problems than similar devices, a hospital said.

The device, developed in Utah and made by WorldHeart, based in Oakland, California, has its only moving part suspended in an electromagnetic field so that it does not touch any other part, the hospital team said.
