CCSVI is a medical procedure. My group in my branch is responsible for approving different products. If a product was to be used and manufacturers wanted to come forward and advertise their product for use in a procedure such as CCSVI, they would have to come through us. To date, to my knowledge, there hasn't been such a claim made for any device. This is really about physicians and surgeons trying something, trying to innovate, trying to fix a problem they notice in their patients. That kind of thing is under the practice of medicine.
In terms of the federal intervention, I think there was a lot of work done across Canada and nationally to see how to handle this. I'm sorry I'm not able to speak to the specifics of that. That's not a regulatory intervention.
