Okay.
I worked in developing countries where I did a fair bit of surgery. I worked a long time in the emergency room. We, as doctors, leave a lot of sutures in people but certainly also coils, stents and replacements. Is there no requirement for the makers of these things that we have historically left in people to do trials beforehand to ensure the safety of what we're putting in people, as they do, for example, in pharmaceuticals, where we have to have phase one, phase two and phase three trials? Is there no equivalent to that for implants?
