The information provided by bard 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 bard.The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint of a stuck guidewire was confirmed and appears to be use related.The alleged and returned sample is an opened niagara short-term dialysis catheter kit.Kit contents include: niagara catheter with stylet, x2 dilators, 70cm guidewire, introducer needle, suture wing, x2 injection caps, and literature.The guidewire was returned within the guidewire hoop with the distal end going through the introducer needle with the pink hub.The "j" tip segment of the guidewire was observed to be extending past the distal end of the introducer needle.Use residue was observed at the distal end of the needle.An attempt to advance the guidewire was unsuccessful and was likely caused by the dried use residue between the needle and guidewire.Microscopic observation of the needle bevel revealed material deformation which was likely cause due to retraction of the guidewire.An attempt to retract the guidewire revealed the guidewire to extend back with slight resistance and felt elastic.The j tip curled when the guidewire was pulled.This is indicative that the core wire was broken.A gripping tool was used to attempted to remove the guidewire from the distal end and the core wire stuck out when the coils were expanded.The guidewire was removed from the distal end of the needle.The proximal end of the guidewire was passed through the introducer needle without issue.The outer diameter of the guidewire was measured and found to be within specification.Since the guidewire was found to be frayed and material damage was observed on the needle bevel, it is likely that the complaint of the guidewire getting stuck in the needle is use related.The ifu states ¿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 recp1735 showed one other similar product complaint(s) from this lot number.
