What about an international health insurance policy that covers repatriation?

I saw in international health insurance policy that overs repatriation. . .can anyone explain what that means?
--------------------
It means, bringing you back to the USA. Example: If you're on a cruise ship, and have a heart attack, you'll have to be flown back to the USA usually by plane from the nearest port's airport, or helicopter. It can EASILY cost $50,000 for that.
