The following were reviewed as part of this investigation: patient severity, complaint and lot history review, applicable previous investigation(s), sample (if available), labeling, applicable manufacture records, and applicable fmea documents.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.Nitinol guidewire, one 21 g introducer needle, and one 4 fr sl power midline with a stylet inserted were returned for evaluation.An initial visual observation showed use residue throughout the returned samples.The distal end of the guidewire was observed to be slightly bent.The core wire of the guidewire was observed to be intact during tactile evaluation.A microscopic observation revealed no damage on the needle bevel.Some delamination was observed in the adhesive at the proximal junction between the core wire and the coiled wire.A gap was observed between the weld tip and the coiled wire.A large amount of blood residue was observed on the coiled wire of the guidewire.While the exact cause of the damage in the guidewire is unknown, possible contributing factors include guidewire caught in patient tissue, forceful insertion/retraction of the guidewire against resistance, and rapid removal of the guidewire.The product ifu cautions: ¿if the guidewire must be withdrawn while the needle is inserted, remove both the needle and wire as a unit to prevent the needle from damaging or shearing the guidewire.¿.
