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 foreign material within an introducer needle is inconclusive due to poor sample condition.One15 cm niagara dialysis catheter, one clear plastic stylet, and a kit label were returned for evaluation.No introducer needle was returned for evaluation.An initial visual observation showed a white crystalline residue within the extension leg of the red lumen.A microscopic observation revealed black and red residue on the hub of the stylet and a greyish residue on the distal tip of the stylet.The introducer needle alleged in the reported event was not returned, and the samples that were returned for evaluation were returned in such a state that it could not be determined where the returned samples may have come into contact with the observed residues.Therefore, this complaint is inconclusive at this time.A lot history review (lhr) of recn0462 showed no other similar product complaint(s) from this lot number.
