I wasn’t sure whether or not this notice had already been posted here so … here is a link to the notice on Medtronic’s website plus an excerpt quoted from the beginning of the notice.
MiniMed Sure-T Infusion Set Needle Break Field Safety Notification
we identified that certain MiniMed® Sure-T® infusion sets* had a slight increase of reported cases where the steel needle broke during use. In a small number of these reported cases, the needle break led to hospitalization for the management of glucose levels and/or treatment for removal of the needle. Since then, an improvement in the needle manufacturing was implemented, which has reduced the number of reported cases of needle breaks.
