Bent cannulas, what to do?
I have been experiencing bent cannulas. I gave been on my pump for a little more than a week and have noticed that every cannula I have removed has been bent at the end between 1/8 to 1/4 inch from the tip. The last one I had to remove because of a no delivery alarm and rising bg levels. My first two set were bent but still working when removed the third was not.
I am using the quick sets that everyone gets with a new pump. I have read that bent cannulas are the result of it hitting muscle. I'm not an overweight person anymore and my BMI is within the normal range but I don't consider myself lean either.
Are the 9mm cannulas I'm using to long or do I need to look into using a different set such as a silhouette.

What I recall from using all the sets available from Medtronic is not necessarely what the infusion set looks like , when removed , but the results of the blood tests taken over the time one has started a new set . I have been using the MM Sure-T's 8 mm and am relatively happy as long as I replace after 2 days and a few hours .

Just to update what I ended up with was the 13mm Silhouettes. I have just started my 2nd box and have not had a single problem since switching. I was OK with the Sure T but the shorter 6mm Quicksets also gave problems. It'll be Silhouettes for me for now on.
Funny thing is that I told my rep before I got my pump that I was not an overweight T2 and they sent me the 9mm Quicksets anyway she said that was the standard for a T2. I'm not complaining Medtronic was great in helping me solve my problem
Thanks everyone for your input.

Are you inserting them by hand? I'm a fan of Silhouettes and always insert them manually. You can insert them at a very shallow angle which is nice to do on areas that don't have much fat. I'm now on an Animas pump and use the Comfort Shorts which are identical to the Silhouettes 13mm. Same manufacturer, different name.

Thanks Nel, I was willing to try anything but didn't know Sure T's were promoted for Kids. I like them but not as much as the silhouettes.
And yes Laddie I do insert them by hand. I did try the harpoon thingy they call a Sil-serter. I found manual insertion to be a much smoother operation. The Sil-serter was for me a bone jarring experience.

I never tried the Silserter because my pump trainer told me that it horrible and that manual insertion was the way to go. I've been using these sets for so long that I mostly ignore the long inserter needle. It's worth a bit of pain to have problem-free sites.
