I can certainly address that.
The medical devices we tend to use in cardiology would be pacemakers, and there are complex pacemakers that pump both chambers at the same time. Even beyond that, there are the implantable cardioverter defibrillators.
I think the regulations have worked quite well, from my experience. I don't implant those devices. I'm not particularly involved in that branch of cardiology, but I would say the biggest hurdle there is more likely on the provincial level, whereby the hospitals have a budget to fund so many implants per year. From my experience, those devices have been well regulated, because we tend to have access to them when we need them, at least in my part of Ontario.
