The following were reviewed as part of this investigation: patient severity, complaint and lot history review, applicable previous investigation(s), sample (if available), labeling, applicable manufacture records, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a bent needle is confirmed but the exact cause remains unknown.One 20 ga x 0.75 in powerloc infusion set was returned for evaluation in open packaging.The packaging label indicated lot: asdyf081.A sharp bend was present on the needle shaft extending from the base.The safety mechanism was not activated.The plastic needle cover was present over the needle.No apparent evidence of use was noted on the device.Microscopic observation of the needle bevel did not reveal any apparent deformation that would suggest advancement against a solid surface.Damage on the proximal end of the plastic needle cover was also observed.The damage on the plastic needle cover likely occurred due to the compression of the needle against the safety base.An attempt to activate the safety mechanism was unsuccessful.An attempt to straighten the needle was made.The safety mechanism was able to successfully activate over the needle tip.Based on the condition of the returned sample, possible contributing factors include damage during storage or handling.Since the bend in the needle was present, the complaint is confirmed; however, the exact location and source of the damage remains unknown.A lot history review (lhr) of asdyf081 showed no other similar product complaint(s) from this lot number.
