On my last "adventure" trip I bought my airline tickets online with my Costco American Express card. There was a link to purchase this emergency insurance: they claimed to offer emergency services up to evac. if needed. Didn't need it, so I don't know if they're any good or not. If memory serves me (which it often fails to do nowadays) it was the same company Pete linked to. It really wasn't that expensive, for the peace of mind it provided. But as I said, I have no experience with actually needing the service.
