Medtronic Mio sets cannula kink?

I recently switched from Animas Ping with the 30 degree insets, to a Medtronic 670g. Because the sets are proprietary, I had to pick something from Medtronic, and I have scar tissue from all my years using the sets. Endo recommended the Mio, since I am really uptight about inserting the sets, an all in one has always worked better for me. At this rate, I’m changing sets three at a time because of kinked cannulas, and it’s getting ridiculous, and expensive. Has anyone else had this issue, or is it just me?

In addition to Mio and other 90 degree infusion sets, Medtronic offers " Silhouette infusion set" which is inserted at between a 30 and 45 degree angle in both 13 mm and 17 mm cannula length. I began using these after building up scar tissue after 50 or 66 years; I now use a similar Tandem infusion set and find the longer length cannula have worked well for me. I also bought an inserter device [large and awkward but works well] from Medtronic.

Good luck finding something that works for you.

I was using the Inset 30 (30 degree insertion) when I had the Animas Ping (Animas no longer in the pump business) for 12 or so years. While the 90 degree was recommended to bypass what scar tissue I might have built up, the main issue is that I am having multiple failures… the inset failed again yester day, making 3 times I have had multiple failures in a row - changing sets 3 or 4 times in the span of a 24-48 period causes aggravation, pain, expense and horribly fluctuating BGs.

Thanks for you suggestions, I will most definitely be looking at other infusion sets.

Hi there. I use Tandem’s T-Slim Pump and Autosoft 30 infusion sets so I’m on a different product. But I wanted to suggest if you have repeated issues be sure to contact Medtronic. Whenever I’ve had an issue with my devices they ask me for the lot number, and if your problems have all been with the same box that could well be the problem. It sounds like you’re an experienced pumper so may have done this, but I thought I would shoot you a reminder in case you haven’t. Wishing you well.

Thank you for your response, WW. I am already looking into other sets, since I have had another round of failures, and made sure I pulled them from a different lot. I will be getting in touch with Medtronic, who so far was very helpful with the transition, and see if they can send me samples of the 30 degree insets. Of course one has to buy the insertion device separately, but might be worth the investment to find something that works for me.
