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, trend 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 reported incident of a knot in the guidewire was confirmed, but the exact cause of the complaint is unknown.The guidewire was received with a slipknot tied 32.5cm from the proximal end of the guidewire.A microscopic examination of the guidewire revealed dislocations in adjoining coils of the coil wire at the knot.A tactual investigation revealed that the coil wire was intact over the core wire.It was reported that the guidewire was advanced in the right basilica vein with resistance during use.It is possible that the wire inadvertently folded over itself and was twisted into a knot within the vein.No manufacturing related defects were noted on the complaint sample.No further action is required because the complainant event could not be related to a deficiency in product manufacture or deficiency while under correct product use.
