you must have a doctor that will be willing to sign the order. then they send it to Medtronic for them to process the order. I had to jump through a few hoop so they felt I would be compliant with intended use of the pump. I have not used the 670g yet but would push you in that direction because it's ability to communicate with the new sensor. If you don't have a doctor yet call Medtronic and they me able to help select one in your area.
