when is dead.. means really dead?

Recently occurred, and once again, a man who had been pronounced dead... minutes or hours later, came back to life... miraculously. The man apparently had a heart attack, massive one, mind you. And after doctors couldn't resuscitate him, he was pronounced dead and were scheduled for organ transplant. Doctors WERE actually in the process of preparation for organ transplant! But I wonder what does the preparation process involved? Were they actually carving out the organs already or were they just preparing the apparatus to do the deed, or what?

Anyway, the moral of the story is... science need a better method to ensure that the human is really DEAD, when they're dead.
