Not the first time this story is on HN. I always wondered - why focus on selling to American hospitals which could not care less?

If the problem is universal, pitch to elite European hospitals, especially Swiss. They cater for rich patients from all around the world and if it's a good idea they'll definitely be interested. Later on, when it catches, American hospitals will come to you too.

Or maybe you will find that European hospitals has already figured this out in some way. Tough story, then.
