In my searching for information on my migraines I came across a clinical trial information website that had the PFO Closure trial on there. It was www.clinicaltrials.gov -- you just type in "migraine" and it brings up all the trials currently going on. There are a few of the PFO closures on there. Also I don't know if you have tried google.com but that brings up a whole bunch of stuff when you type in "PFO closure trials". That's all the info I have on it.
It sounded kinda scary to me too!!!
