H11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.The following were reviewed as part of this investigation: patient severity, complaint and lot history, applicable previous investigation(s), labeling, applicable manufacturing records, and applicable fmea documents.Based on a review of this information, the following was concluded: the complaint of a damaged guidewire was confirmed but the exact cause is unknown.One guidewire from a niagra dialysis catheter kit was returned for investigation.A kink near the j tip portion of the catheter was present.The coil near the kink location was slightly spread apart.The rest of the coil wire was intact with both weld tips present at the distal ends.A label sticker was also returned with lot: rect0894.The introducer needle was not returned.Microscopic observation revealed no apparent evidence of contact with the needle bevel.Manipulation of the proximal end of the guidewire revealed it to rigidly jerk.The proximal end of the guidewire was cut and the coil wire was unraveled to check the core wire integrity.No breaks in the proximal end of the core wires were observed.The kink at the distal end of the guidewire likely affected the mobility of the proximal end of the guidewire.Since a kink in the wire was observed and likely contributed to the reported event, the complaint is confirmed; however, the exact cause remains unknown.Possible contributing factors include retraction of the guidewire against the needle bevel and advancement against resistance.The product instructions for use (ifu) cautions, "caution: do not pull back guidewire over needle bevel as this may sever the end of the guidewire.The introducer needle must be removed first.Also, if unusual resistance is met during manipulation of the guidewire, discontinue the procedure and determine the cause of resistance before proceeding.Withdraw needle and guidewire if cause of resistance cannot be determined." a lot history review (lhr) of rect0894 showed no other similar product complaint(s) from this lot number.
