When I was getting ready to go in for mine to be closed I was offered a choice of two by Dr Turner, the Amplatzer or the Gore Helex (
LINK), I looked at both before deciding but went for the Amplatzer as it had a shorter healing time and I had read more about the device being fitted.
I must admit this device on the original post sounds good though with only a 30 day heal time.
Still about 5 weeks until I find out whether I'm still open or closed.
