I can honestly tell you that you have no idea of what you are speaking. I work for a small medical device manufacture as a software architect/engineer. There are many reasons why a medical device is expensive. I'll enumerate the two that I have experience with. The first, and biggest is the FDA. We are a class 2 medical device, much like the piece of equipment mentioned in the article.
So what does this mean? It means reams and reams of paperwork. Not nearly as much paperwork his required for a class 2 as a class 3 (pace maker and other implantable devices) device, but still reams of paper. We sent almost a WHOLE box of paper to the FDA when we submitted our paperwork. If I had to add up the cost to produce the paperwork, given the cost of lawyers, and staff time, my guess would be >$250k. Thats just the initial cost. We now have to get ready for an FDA compliance audit in the next few months. We have also have to overhaul how we develop the software. We have to be able to trace every line of code back to reams of paperwork, that adds an additional burden to the bottom line.
Next are lawyers. We spent a TON of money on lawyers while doing our FDA 510K. Competent lawyers who are also knowledgable about the FDA 510K process are NOT cheap. ONE of the lawyers we used cost $600/hr.
You also have to remember that the medical market is quiet limited. How is a small medical device company supposed to survive if they sell the device for a couple of hundred dollars into a very limited market?
When you see our product, you might be tempted to think $5000? I'm not paying that much for a metal frame, a hardened PC w/ a touch screen and some software. Its not worth that much. And when you do, I want you to tell that to me personally, to my face. I also want you to tell me that my family doesn't deserve to eat.
