First, i agree that you should contact your Medtronic rep. I'm on a different system, but a good idea is to connect to the online groups out there like TuDiabetes.org and the diabetes group on Reddit (http://www.reddit.com/r/diabetes/
). In a pinch, Insulin-Pumpers.org was incredibly helpful to me when I needed supplies. There might be folks there that are near you or who can guide you to help.
