A friend of my dad's developed a low-cost medical device for use in Africa. It worked, but not as well as expensive devices, and it wasn't taken up. There's a lot of bureaucracy that stands in the way of getting affordable (but less advanced) medical equipment onto the field. On the other hand, if you want to field test an expensive device in a third world country, you can lobby the right people and splash a few bribes around. The Constant Gardener (fictional, yes, but I doubt it's far from the truth) is about this. Cheap devices aren't worth the effort.
