Friend's wife in medical emergency

I'm trying to raise money for my friend. His wife has recently been hospitalized with a condition that the doctors currently can not fix or even fully diagnose. She has been in a medical induced coma and has been having a lot of seizures. Doctors at the current hospital have not been able to improve her condition. They now have to send her to a specialist at the Mayo clinic out of state. I'm trying to help raise money to get a very good friend through a very tough time. Anything anybody could give would be greatly appreciated and go to a family in a terrible situation.
