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 insertion difficulty between the guidewire and stylet was confirmed but the exact cause remained unknown.The product returned for evaluation was a 0.038¿ x 70cm stainless steel guidewire.The wire was returned inlaid within what appeared to be the clear stiffening niagara stylet.The wire was bent in several locations proximal of the stylet luer and was bent in three locations within the clear stylet, just distal of the luer.The stylet was unremarkable to gross visual evaluation.Blood residue was seen within the stylet indicating use.An attempt to functionally advance the guidewire revealed excessive force was required to further advance the wire.Advancement of a non-complainant guidewire was unremarkable and advancement of the complainant wire was unremarkable up until the point of the observed bends in the wire.The wire was then withdrawn and examined by microscope.No disjoining of coils, or hard kinks in the wire, were observed.The wire and stylet were both measured to be within specification and no obvious manufacture caused damage, defect, or deformity was observed.It was apparent that the bends in the wire were the cause of insertion difficulty, but the timing of, and location where, the bends were introduced was unknown and consequently the cause was ultimately unknown.The bends in the wire could have been introduced at the time of use or were preexisting.No evidence was observed which could conclusively determine which was the case.
