How much will cost to build a microcontroller by experts?

Yes, very true.
But by now I hope we all realize Robin is exercising his usual off-beat British humor (hey, I love BBC America, so I go for this stuff). I don't think anyone is really thinking about putting out substantard products -- medical or otherwise -- then running from the law.
One small note about the FDA: they get involved only if certain medical claims are made, or if the drug/device is dangerous in its use. A device that claims to cure cancer will come under the scrutiny of the FDA. One that promotes "vim and vigor" probably will not. This is why so many homeopathic and herbal remedies specifically disclaim that they are intended for any specific ailment.

what
[Zagan] Yes, of course.

[Zagan] Apparently my small company did fall into the scrutiny of the FDA. There was nothing particular dangerous about our product, but a mis-diagnoses by one of our users could result in legal problems if someone lost their teeth due to a mis-diagnoses. While I was there we were visited and sited for several violations. Most of this had to do with record keeping and documentation on how to produce the product. I was the programmer, and curiously the inspector considered what I did to be R&D and was not interested. I was prepared to provide a complete demo of how I did the programming and made backups, but she said that was not an issue they were interested in. I found that to be odd. The hardware worked perfectly, but it was up to the software to keep records for a given patient. The software, in my opinion, was the weakest link, but the inspector cared more about record keeping than what I was doing.
I think this is a mistake on the part of the FDA. They seemed more concerned about record keeping than the programming I did. I didn't get to complete my demo since she said that was R&D and they weren't concerned about that. Go figure.

This should have told you a lot about what the FDA is used for.
They only wanted to know who would be libel, not how you did your job.
Remember, bureaucracy is only interested in bureaucracy not technology.

That depends on the contract.
For example, I claim that I have not knowingly violated any patent rights, but that's all I can claim without being paid *much* more. I'm not sure what I'd charge for a complete patent search on my software vs the patent office, but I'd guess it would be in excess of $10,000 for a fairly small program, and going up quickly with the size of the program.
And I wasn't talking about modifying an existing microcontroller. That's a chip. Why go to all that trouble. If you really want to create a brand-new microcontroller, use an FPGA, but I wouldn't even think of that at this stage in the process. Figure out exactly what you want to happen, not *how* it happens. If you want to control a Segway, then figure out what you want to control (I want it to be able to be used as a robot body, doing everything a human rider can do with it), not (I want to use a PIC to do things).
Why not use or make a board with an *existing* microcontroller, such as a PIC or a PSoP or any of the other fine microcontrollers out there? These things are desgined to be used in commercial packages.
For example, I use the JStamp in some of my designs. This is about the size of the BASIC Stamp and costs only a bit more per unit, but is directly programmed in Java, and has 0.5 Meg of Flash and RAM. Since I like robotics, I *like* the additional memory and the convinience of programming in a high-level language. If I buy one, I'm allowed to do pretty much anything with it, including put it into a commercial product.

I rather doubt you'll find a good contractor with requirements that vague.
My day job is for Penn State, and even faculty usually give me better requirements than that. And my boss keeps laughing when I request a purchase order for thumbscrews. :) -- D. Jay Newman

Hi,
I have designed microcontroller based medical devices. I signed on as an employee rather than a contractor. You can't sue someones employee - at least not as easily.
If you don't have about $1 million in backing right now, I would suggest not trying such a project. Also, if anyone is 'sure' they can make such a thing work, look for someone with a lot of experience and a good track record who is 'not sure'.
