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 damaged guidewires was confirmed, but the exact cause was not determined.A 0.018¿ x 35cm guidewires and a microintroducer was returned for investigation.The guidewire was received in the hoop.The blue tip straightener was not attached to the hoop.The guidewire was extending 9.2cm from the distal end of the hoop.A bend was observed 1.7cm from the distal (exposed) tip of that guidewire.Two less prominent bends were observed 4cm and 8cm from the distal tip.No residue was observed on the microintroducer.A microscopic examination revealed that the weld tip and coil wire was intact at the distal end of the guidewire.Dislocation in the coil wire was observed at the proximal weld tip of the guidewire.The grind pattern on the coil wire was misaligned, which indicates that the dislocation occurred after the guidewire was manufactured.The outside diameter of the guidewire was within specification.This type of damage can occur if the coil wire is twisted near the weld tip; however it is unknown where or how the damage occurred.A lot history review (lhr) of rebw0774 showed six other similar product complaints from this lot number.
