As for the Medtronic sets, try the Silhouette sets. No auto-inserter needed, and they’re actually far less prone to problem than the auto-inserted sets such as QuickSets. Furthermore, if you want to use non-Medtronic sets (ie those with a luer Lock) with a Medtronic pump, you can get a converter. The only issue may be persuading your CCG to fund you supplies from two different manufacturers, depending how picky they are about such things. But in this case you just need to give them evidence of why you need to do so.
