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 is confirmed and was determined to be use related.One 0.018 in.Nitinol guidewire and one 21 g introducer needle were returned for evaluation.An initial visual observation showed blood residue throughout the returned samples.The safety mechanism of the needle was deactivated and an attempt was made to push the guidewire through the needle.The guidewire began to move, however, the amount of dried blood residue within the needle prevented the guidewire from being pushed any further.The guidewire was able to be pulled out of the needle, with some resistance.A microscopic observation revealed the needle bevel was damaged with its edges deformed and lustrous.A large amount of residue buildup was observed about 1 cm proximal to the distal tip of the guidewire.The weld tip was observed to be present and intact, but the outer coiled wire appeared to have the damage observed on the guidewire and the needle tip, as well as the amount of blood/tissue residue, indicates the guidewire was most-likely damaged during use.The product ifu states: ¿if the guidewire must be withdrawn while the needle is inserted, remove both the needle and wire as a unit to prevent the needle from damaging or shearing the guidewire.¿ a lot history review (lhr) of reby1234 showed no other similar product complaint(s) from this lot number.
