I get my Silhouette infusion sets and reservoirs directly from Medtronic. In reading some of the preliminary writing about this recall issue, I was confused about the reference to a “membrane” that’s at the heart of this.
Medtronic sent me an email today explaining their recall. One of their links brought me to a pdf file for Silhouette infusion sets. (Other links lead, presumably, to other infusion sets that are part of this recall.) The following section of that pdf file explained things more clearly to me.
I conclude from this that it’s important to keep the area around the base of the tubing connector needle (the membrane) dry so that the priming function can operate normally. Medtronic does not want anyone to use any of the recalled lot numbers.
