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 damaged guidewire is confirmed; however, the exact cause is unknown.One 0.018 in.Guidewire was returned for evaluation.An initial visual observation showed the guidewire was bent in three locations and the proximal end was observed to be slightly curved.The core wire of the guidewire appeared to be intact during tactile evaluation.A microscopic observation revealed the coiled wire at the proximal tip of the guidewire was deformed and some coils were displaced.The distal end of the guidewire was observed to be undamaged.The undamaged distal end of the unraveled guidewire was twisted firmly and repeatedly in an attempt to recreate the failure, and after this repeated twisting, the coiled wire at the distal end was observed to become deformed in a similar way as the proximal end of the guidewire.It is possible this damage occurred during manufacturing, packaging, handling, or use; however it is not possible to determine when or where it took place.A lot history review (lhr) of rebx0604 showed no other similar product complaint(s) from this lot number.
