Here's a medical feat. A breakthrough! French surgeons implanted a Carmat artificial heart in a human patient for the very first time. It combines mechanical components and heart tissue derived from cows, designed to be used for up to five years.

The Carmat heart was designed for up to five years use, employing flexible, hydraulically-operated chambers that squeeze instead of pump, the blood into the circulatory system. It is lined with natural bovine heart tissue to prevent clotting.

Being made for heavy duty use comes with a cost. It weighs 2lbs, - three times as much as the average human heart, and costs more than $200,000. The Paris patient who received it on Wednesday is now awake and talking. [Reuters]
